The Lambretta exhaust systems in the test

Before we sent the final sample to Spain, the new box was put through its paces again. Lambretta exhaust test: Another prototype box from our friend Chalky from Replay Scooters and JPP  came directly to the test bench:

  • bgm PRO BigBox Proto
  • JPP box prototype

The following resonance racing exhaust systems competed against the pits:

  • the TSR Evo,
  • the JL3 and
  • in MB3

And all three Reso systems did better against the speakers than we would have expected!

The Lambretta engine

The test engine was constructed as follows:

 

Result & conclusion of the test

Nice and clear to see how good the box is from the start Performancebut also with plenty of torque scores in comparison to the 'racing exhaust systems'.

This is exactly what makes the bgm PRO boxes so nice to drive. There is always enough power available without having to struggle with gear connection problems or having to turn the gas like crazy to get things going.

The moderate consumption values ​​of the engine concepts with the bgm boxes are another advantage, apart from the original look and the pleasant background noise. Another outstanding feature is the protected fastening system with adjustment options in both horizontal and vertical directions. This allows tolerances and, above all, spacers used to be compensated for different strokes and connecting rod lengths.

Comparison of Malossi ROAD BGM

What does the MALOSSI banana bring?

With the Vespa Largeframe have powerful exhaust systems, so-called Box exhaust systems, established in an almost original look. We have with the bgm PRO BigBox Touring and the Big Box Sports 2 optimized BigBoxes in the program.

Scooter Center - home of bgm

This development also applies to the Vespa Smallframe Indent.

Since we are with the bgm PRO BigBox Banana are also working on such an exhaust system, we have them Malossi banana used directly for a comparison.

Bananas among themselves: Malossi VS Road Banana

Here in direct comparison to the previously available road banana.

From a purely visual point of view, the two exhaust systems initially differ in the pressed manifold at Malossi and the manifold made up of segments in the road system.

The test engine for the bananas

For our tests we used a proven engine, like the one in class 5 (K5) of the European Scooter Challenge is used.
With well-known components that can only be plugged together in this class, this motor concept is both simple and durable and can be reproduced at any time. So no exceptional super special professional unit, but down-to-earth home cooking that is fun over the long term and can be easily set up by anyone.

Our test engine therefore consists of the following performance-influencing components:

On the diagram you can see that the Malossi banana is slightly above the road banana.
In the range between 5500 rpm and approx. 6700 rpm, the Malossi exhaust is slightly ahead.

Full of banana!

 

bgm PRO BigBox Banana

Since we are also working on an exhaust for the Smallframe work, the direct comparison with the Malossi banana was of course very exciting.

From top to bottom:

  • Malossi banana
  • Road banana
  • bgm PRO BigBox Banana

For the purpose of better accessibility, we decided to use a position as the separation point for the manifold for the BGM-Banana, which can also be easily reached with the spring-loaded hook on the classic V50 and Primavera and yet is not in the immediate field of vision. The lower holder is designed in such a way that two springs can be hooked in here without any problems.

The super banana: bgm PRO banana brings 2PS

The BGM banana already cuts a fine figure on the test engine. So far we are quite satisfied with the results ...

Between 5700rpm and 8700rpm, the bgm Pro-Banana averages almost 2HP over Malossi.
The torque, which is important for propulsion, is also clearly in this speed range above that of the other test subjects.

Delivery date bgm Pro BigBox Banana

We hope that we will have the exhaust ready for you by the start of the 2018 season.

 

 

Exhaust -BGM PRO BigBox SPORT (BBS) - Vespa PX200, Rally200 Item no. BGM1011SP

Now available again: bgm BigBox Sport exhaust Vespa PX200

Performance like a racing exhaust - optics and acoustics like a series exhaust

The BGM BigBox Sport is a thoroughbred Vespa racing exhaust, in the unsuspicious design of an original exhaust. Just like the original Vespa exhaust, the BigBox is of course double-walled and provided with insulating wool. It positions itself as a clear alternative to eye-catching and mostly loud copies of our original BigBox and large resonance exhaust systems. The high level of motivation clearly sets the bgm BigBox Sport apart from other boxing facilities. Designed for performance-oriented drivers who appreciate the benefits of an inconspicuous vehicle.

Real Vespa racing exhaust

The Sport Box, like everyone else, needs it good racing exhaust, a powerful engine concept to develop your full performance. In the environment of cylinders such as the Polini 210, Malossi MHR and Co., it offers impressive results. It also supports engine outputs above 25PS without any problems and pushes ahead with full torque. Despite its high peak performance, the Sport Box gets in early and also enables comfortable driving.

Due to its consistent design for a high gas throughput, the BigBox Sport is not intended for use with near-series engines or tame tuning cylinders. It needs a clear and powerful outlet impulse to fill the large volume and the thick elbow of the Sport Box with life.

Order your Vespa sport exhaust now

PRO:

  • Original optics
  • Quiet thanks to the double wall and insulation wool like the original exhaust
  • Top performance like a resonance exhaust
  • No performance hole
  • Broad speed range
  • More top speed
  • Very unobtrusive
  • Also fits rally / sprint without modifications
  • Solid construction with clamp on the cylinder
  • Handcrafted in Europe

CONS:

  • Not for vehicles with 8 inch tires (ground clearance too low)
  • Not for near-series engines

Heads-up: Choose the main jet about 4-6 sizes larger than with the original exhaust.

The elbow is attached to the cylinder using a clamp. Compared to loose fastening with an O-ring seal, this results in the best stability and prevents damage to the outlet flange. A long spacer should be used on the rear shock absorber for optimal ground clearance.

And finally ...

Pure understatement. Performance like a racing exhaust, optics and sound similar to an original exhaust.

Vespa T5 big box review SLUK

bgm BigBox Vespa exhaust for T5 is test winner

Our Racing exhaust for Vespa has been tested again. And again it is the test winner with the greatest performance. In that case it became ours BigBox for the Vespa T5 from UK online scooter magazine SLUK tested. Here is a video of the test:

BGM BigBox Touring for Vespa T5

The bgm BigBox Vespa T5 is designed as a replacement for the original sensationally good exhaust system of the Vespa PX special model T5. The T5 engine designed by Morini has some peculiarities due to the adapted powerful 125cc motorcycle cylinder.

The T5 engine reacts very strongly to the exchange of the exhaust system. The BGM BigBox for the T5 is based on the standard exhaust in order to keep the torque in the lower and middle speed range at a similarly high level as the standard exhaust. Depending on the setup, it can turn out a little further.

Nice to see at our customer Nino in Portugal, Original T5 with the bgm BigBox. Seems to be fun:

Conclusion

Nice to see in the diagrams: ours bgm BigBox harmonizes with the original engine as well as with Polini 152 or Malossi 172 tuning cylinders. On revised engines, the larger volume of the BigBox Touring results in a significantly better torque and power curve than with the original exhaust.

La Vespa in Spain

The scooter market in Spain is very strong and has a long tradition. Spain is one of the largest markets for scooters in Europe and in addition to new vehicles there is also a lively market for scooters in Spain used Vespas. Many lovers of classic Vespas are looking for restored or well-preserved older models to revive the charm of bygone times.

Here are some of the parts that will keep Vespas on the road for many years:

Moto Vespa Spain

Motovespa 160GT
The Motovespa 160 is one of the most sought-after vehicles from Spanish production.
The leg shield is vaguely reminiscent of the iconic Vespa SS50 and SS90 and, in conjunction with the trapezoidal headlight, gives the 160GT an elegant, sporty look.
The engine of the 160 and 160GT already shows some technical features similar to the big sister SS180 from Piaggio.
For this engine type, we had bgm reproduce some components that were no longer available or difficult to obtain.

Brake T5 rear 005 (2)

Conversion to adjustable brake cable Vespa PX, Rally, Sprint,

The brake pad wear of the front brake of the PX series up to 1998 and the PK-XL can be easily adjusted without tools using the well-known knurled screw on the brake cable.

On the Vespa PX125T5, this luxury can even be found on the rear brake.
With this model, Piaggio has already seen that the fiddly-to-use adjusting screw in hard-to-reach places is no longer state-of-the-art.

We leave the no longer available Piaggio original part of the T5 in excellent quality reproduce.

Greater braking force with the same pedal force

The brake arm fits almost all Vespa Largeframe Models and is one meaningful improvement especially for all PX before 1984, as well as rally, sprint and co, because the brake arm is longer and a greater braking force is generated with the same pedal force.

Our practical conversion kit

With the Set for retrofitting every PX can be brought up to the state-of-the-art.

The solution for perfectionists with a T5 brake cable

In order to carry out the conversion, a slot must be made in the cable guide of the brake pedal. The T5 brake cable has a cast nipple at each end and can therefore no longer be threaded through the bare hole in the cable guide on the pedal. In addition, the M8 set screw on the PX engine blocks must be removed and drilled to the size of the brake cable abutment.

 

 

The simple adapter solution

Those who shy away from the effort described above can easily fall back on the variant with our adapter for the pulling thread:

If the brake cable is not to be completely replaced, we also offer a fast one Adapter solution

Conversion for Largeframe Our Oldies

For the Vespa Largeframe Models with an external brake pedal, such as Vespa Rally, Sprint, VNA, VNB, etc., can also be converted either with the adapter or with one loose brake cablethat has one end with the matching thread.

The simple installation using a Vespa PX

Here we briefly present the conversion using the example of a Vespa PX.

In order to be able to replace the brake arm, it is necessary to remove the brake cam.
In order to gain access to the cam, the rear wheel and the brake drum are dismantled.

 

cap and Sapwood remove

 

 

Dismantle the rear wheel

 

and then the brake drum remove.
ohne impact wrench is the Holding tool for Vespa and Lambretta brake drums a real help.

 

 

If the brake drum is removed, the brake shoes are freely accessible. Here it is worth taking a look at the position of the brake cam.
If the cam is almost 45 ° inclined to the brake shoes with the brake pedal unloaded, as shown here, this is an indication that the Brake shoes are soon worn out.

 

 

 

In order to be able to pull the brake cam a bit out of the guide, it is necessary to Brake shoes to remove. the Retaining rings can be removed quite easily.
However, care should be taken to secure the little nasty things against jumping away.

 

 

 

 

With a wider one screwdriver the jaws can be spread apart and removed one at a time. Shouldn't the brake shoes
are replaced, it makes sense to mark the installation position on one of the brake shoes. As can be seen in the picture above based on the abrasion,
the approaching brake shoe is subject to a different wear pattern than the decelerating brake shoe. Therefore, it makes sense to remove the brake shoes when reassembling
to put them back in their accustomed place.

 

 

After unhooking the spring for the brake arm is the Safety split pin accessible. Once the split pin has been removed, the Brake cam pulled out
become and gives the Feder and the brake arm free.

 

 

 

The brake cam is provided with a franking in which a Fat storage is introduced for long-term lubrication. Just fill up if necessary.

 

 

If the brake cam has the latest lubricant technology, the brake arm and the spring can be installed.

 

 

Do not forget the cotter pin before attaching the spring.

 

 

In this case, new brake shoes are used. To protect the guides from corrosion and to prevent the brake shoes from seizing up,
will be here copper paste applied.

 

With the main shaft as support, the brake shoes are placed in the guides.

 

 

The Mother the Lusso main shaft with SW24, for example, is fitted with a torque fastened by 110Nm.

 

 

Before cutting the old inner cable to length, check whether the Adjusting screw is on “0”.

 

The required pull length for the adapter can be determined based on the position of the brake arm. The pull should be right right up to the end of the arm
are sufficient. the Cable shears ensures a clean and safe cut without the cable fraying.

 

 

Push the adapter up to the end of the inner cable and secure it with the clamping screw. After the first test braking, check whether the end of the train
is still in the same position. If not, the clamping screw must be checked and retightened.

 

 

So that the adjusting nut on the adapter is easy to move at all times and does not corrode, a little copper paste can also be used here.

 

 

Mount the rear wheel again and the wild ride can go on.

 

Pinasco

Motor housing Vespa T5 from Pinasco

Just got us from Pinasco the news reaches us that the long-announced engine housings for the Vespa T5 should arrive next Thursday.

The engine housings of the rare Vespa PX125T5 have always been few and far between. We are all the more pleased that something is happening again with the products for the T5.

Diaphragm and rotary valve engines for Vespa T5

Pinasco now offers two alternatives. Like the PX motor housings also, it will for the T5

  • a classic Rotary valve (Master) and article number: PN26482024
  • a motor housing with Membran (Slave) give. Item number: PN26482025

In terms of price, the T5 motor housings are slightly higher than the PX variant lie.

More technical details We can only give you this when we have received the first motor housings in the next few days. We keep you here in Scooter Center Blog up to date.

Build T5 engine

The easiest way to complete such an engine is to order the appropriate engine revision kit: Engine revision set Vespa 125T5

Engine revision set -OEM QUALITY- Vespa T5 125cc article no. 3330409

Information about a super suitable Exhaust you find here Vespa T5 exhaust

bigbox-vespa-t5-bgm1012tr4

First pictures of the Pinasco T5 engine

Here are some pictures that Pinasco made available to us.

The motor housings are expected to be delivered with all fixed stud bolts and suitable silent rubbers for the motor cross-member and shock absorber mount.

 

Pinasco engine housing for Vespa

The Pinasco motor housings are very high quality replacement motor housings made of the finest die-cast aluminum. In addition to the very precise processing, they also offer many special features that are particularly interesting for tuners.
In addition to the significantly larger sealing surfaces on the cylinder base and carburetor inlet, Pinasco also offers the housing as a version with a diaphragm inlet. This suction technology, which has long been standard in the automatic sector, also offers large carburettors a good passage to breathe deeply. Further reinforcements in the cast, a larger crankshaft bearing and the great scope of delivery round off the superb overall picture of the Pinasco engine housing perfectly.

The housings are manufactured in two variants:
MASTER = ROTARY VALVE INLET (LIKE FROM THE PIAGGIO FACTORY)
SLAVE = DIAPHRAGM CONTROLLED

The engine internals and ignition components of all 125-200ccm models from 1982 onwards can be taken over. The components built from 1984 onwards are preferable due to the improved and more stable gearbox and the more powerful alternator. The motor of the COSA models is also well suited as a donor motor. Their engine block is outwardly different, but uses the same innards as the PX models from 1992 onwards.

Both versions have the same useful improvements:

  • MATERIAL
    High quality die-cast aluminum with a fine surface
  • SEALING SURFACES
    Very precisely milled sealing surfaces
  • STRONGER
    Reinforcing ribs in the area of ​​the main shaft bearing on the switch latch side and the shock absorber mount
  • SOLID
    Significantly more material in the area of ​​the cylinder base sealing surface and the carburetor inlet
  • OIL SEAL
    The housings are made to accommodate a metal shaft seal (coupling side). Please always use the version for the 200cc versions with a brown sealing lip.
  • FIT
    Two additional fitting bushes = crankshafts with an excessively long stroke can do without the centering edge of the Lima half. Dimensions of fitting bushes AØ = 9,95mm, IØ = 8,40mm, h = 13,80mm
  • RUBBER
    The holes for the large silent rubbers are Ø = 44mm (original Piaggio Ø = 43mm).
    The enclosed silent rubbers are stiffer and offer better guidance of the motor in the frame.
    Piaggio silent rubbers also fit. Solutions with metal bushing or without pre-tensioning usually do not fit if they were manufactured for Piaggio engine housings (Jockey, PLC).
  • NUMBER
    The motor housings do not have an embossed motor number or prefix
  • OIL HOLE
    No drip hole for gear oil = the nonsensical drip hole that shows whether the inner shaft sealing ring is defective has been left out *.

* Our tip: run the sealed bearing and external shaft seal with the appropriate brake drum.


SPECIAL FEATURES ROTARY VALVE VERSION
- Extra large sealing surface over both engine halves, suitable for all intake manifolds
- Can be used as a 1: 1 replacement for an original motor housing
SPECIAL FEATURES OF THE MEMBRANE VERSION
- Central, full-surface membrane inlet
- Incl. Membrane intake, incl. Membrane in RD350 format (hole 58x48mm)
- Suction rubber can be rotated 360 °, connection width carburetor = Ø34mm
- Rubber suitable for Keihin PWK28, Mikuni TMX27 / 30, Dell'Orto PHBH28 / 30, VHS24-30
- No cast-in axis for oil pump control
- No hole for oil pump drive

The enclosed fitting bush for the auxiliary shaft must be inserted by yourself
If transmission components other than those of the PX models from 125cc are to be used, please check the auxiliary shaft axis for compatibility beforehand and change it if necessary.
Please insert all stud bolts with high-strength screw adhesive. The cylinder studs are not oversized on one side, as is the case with the original Piaggio. Therefore, glue in the supplied Pinasco cylinder studs here as well. We recommend cutting all threads and cleaning them with compressed air.
ASSEMBLY NOTE:
The crankshaft bearing NU205 on the alternator side is not seated flush in the engine housing.
It protrudes approx. 1mm towards the crankshaft.

DELIVERY

· ROTARY VALVE
- All studs
- Silent rubbers + washers for silent rubbers
- Housing seals
- Bushing for auxiliary shaft axis

· MEMBRANE
- as above, additionally included:
- Intake manifold including membrane, suction rubber, seal and small parts

Comparison of Malossi ROAD BGM

What does the MALOSSI banana bring?

With the Vespa Largeframe have powerful exhaust systems, so-called Box exhaust systems, established in an almost original look. We have with the bgm PRO BigBox Touring and the Big Box Sports 2 optimized BigBoxes in the program.

Scooter Center - home of bgm

This development also applies to the Vespa Smallframe Indent.

Since we are with the bgm PRO BigBox Banana are also working on such an exhaust system, we have them Malossi banana used directly for a comparison.

Bananas among themselves: Malossi VS Road Banana

Here in direct comparison to the previously available road banana.

From a purely visual point of view, the two exhaust systems initially differ in the pressed manifold at Malossi and the manifold made up of segments in the road system.

The test engine for the bananas

For our tests we used a proven engine, like the one in class 5 (K5) of the European Scooter Challenge is used.
With well-known components that can only be plugged together in this class, this motor concept is both simple and durable and can be reproduced at any time. So no exceptional super special professional unit, but down-to-earth home cooking that is fun over the long term and can be easily set up by anyone.

Our test engine therefore consists of the following performance-influencing components:

On the diagram you can see that the Malossi banana is slightly above the road banana.
In the range between 5500 rpm and approx. 6700 rpm, the Malossi exhaust is slightly ahead.

Full of banana!

 

bgm PRO BigBox Banana

Since we are also working on an exhaust for the Smallframe work, the direct comparison with the Malossi banana was of course very exciting.

From top to bottom:

  • Malossi banana
  • Road banana
  • bgm PRO BigBox Banana

For the purpose of better accessibility, we decided to use a position as the separation point for the manifold for the BGM-Banana, which can also be easily reached with the spring-loaded hook on the classic V50 and Primavera and yet is not in the immediate field of vision. The lower holder is designed in such a way that two springs can be hooked in here without any problems.

The super banana: bgm PRO banana brings 2PS

The BGM banana already cuts a fine figure on the test engine. So far we are quite satisfied with the results ...

Between 5700rpm and 8700rpm, the bgm Pro-Banana averages almost 2HP over Malossi.
The torque, which is important for propulsion, is also clearly in this speed range above that of the other test subjects.

Delivery date bgm Pro BigBox Banana

We hope that we will have the exhaust ready for you by the start of the 2018 season.

 

 

Exhaust -BGM PRO BigBox SPORT (BBS) - Vespa PX200, Rally200 Item no. BGM1011SP

Now available again: bgm BigBox Sport exhaust Vespa PX200

Performance like a racing exhaust - optics and acoustics like a series exhaust

The BGM BigBox Sport is a thoroughbred Vespa racing exhaust, in the unsuspicious design of an original exhaust. Just like the original Vespa exhaust, the BigBox is of course double-walled and provided with insulating wool. It positions itself as a clear alternative to eye-catching and mostly loud copies of our original BigBox and large resonance exhaust systems. The high level of motivation clearly sets the bgm BigBox Sport apart from other boxing facilities. Designed for performance-oriented drivers who appreciate the benefits of an inconspicuous vehicle.

Real Vespa racing exhaust

The Sport Box, like everyone else, needs it good racing exhaust, a powerful engine concept to develop your full performance. In the environment of cylinders such as the Polini 210, Malossi MHR and Co., it offers impressive results. It also supports engine outputs above 25PS without any problems and pushes ahead with full torque. Despite its high peak performance, the Sport Box gets in early and also enables comfortable driving.

Due to its consistent design for a high gas throughput, the BigBox Sport is not intended for use with near-series engines or tame tuning cylinders. It needs a clear and powerful outlet impulse to fill the large volume and the thick elbow of the Sport Box with life.

Order your Vespa sport exhaust now

PRO:

  • Original optics
  • Quiet thanks to the double wall and insulation wool like the original exhaust
  • Top performance like a resonance exhaust
  • No performance hole
  • Broad speed range
  • More top speed
  • Very unobtrusive
  • Also fits rally / sprint without modifications
  • Solid construction with clamp on the cylinder
  • Handcrafted in Europe

CONS:

  • Not for vehicles with 8 inch tires (ground clearance too low)
  • Not for near-series engines

Heads-up: Choose the main jet about 4-6 sizes larger than with the original exhaust.

The elbow is attached to the cylinder using a clamp. Compared to loose fastening with an O-ring seal, this results in the best stability and prevents damage to the outlet flange. A long spacer should be used on the rear shock absorber for optimal ground clearance.

And finally ...

Pure understatement. Performance like a racing exhaust, optics and sound similar to an original exhaust.

Vespa T5 big box review SLUK

bgm BigBox Vespa exhaust for T5 is test winner

Our Racing exhaust for Vespa has been tested again. And again it is the test winner with the greatest performance. In that case it became ours BigBox for the Vespa T5 from UK online scooter magazine SLUK tested. Here is a video of the test:

BGM BigBox Touring for Vespa T5

The bgm BigBox Vespa T5 is designed as a replacement for the original sensationally good exhaust system of the Vespa PX special model T5. The T5 engine designed by Morini has some peculiarities due to the adapted powerful 125cc motorcycle cylinder.

The T5 engine reacts very strongly to the exchange of the exhaust system. The BGM BigBox for the T5 is based on the standard exhaust in order to keep the torque in the lower and middle speed range at a similarly high level as the standard exhaust. Depending on the setup, it can turn out a little further.

Nice to see at our customer Nino in Portugal, Original T5 with the bgm BigBox. Seems to be fun:

Conclusion

Nice to see in the diagrams: ours bgm BigBox harmonizes with the original engine as well as with Polini 152 or Malossi 172 tuning cylinders. On revised engines, the larger volume of the BigBox Touring results in a significantly better torque and power curve than with the original exhaust.

Vespa Spain

La Vespa in Spain

The scooter market in Spain is very strong and has a long tradition. Spain is one of the largest markets for scooters in Europe and in addition to new vehicles there is also a lively market for scooters in Spain used Vespas. Many lovers of classic Vespas are looking for restored or well-preserved older models to revive the charm of bygone times.

Here are some of the parts that will keep Vespas on the road for many years:

Moto Vespa Spain

Motovespa 160GT
The Motovespa 160 is one of the most sought-after vehicles from Spanish production.
The leg shield is vaguely reminiscent of the iconic Vespa SS50 and SS90 and, in conjunction with the trapezoidal headlight, gives the 160GT an elegant, sporty look.
The engine of the 160 and 160GT already shows some technical features similar to the big sister SS180 from Piaggio.
For this engine type, we had bgm reproduce some components that were no longer available or difficult to obtain.

Brake T5 rear 005 (2)

Conversion to adjustable brake cable Vespa PX, Rally, Sprint,

The brake pad wear of the front brake of the PX series up to 1998 and the PK-XL can be easily adjusted without tools using the well-known knurled screw on the brake cable.

On the Vespa PX125T5, this luxury can even be found on the rear brake.
With this model, Piaggio has already seen that the fiddly-to-use adjusting screw in hard-to-reach places is no longer state-of-the-art.

We leave the no longer available Piaggio original part of the T5 in excellent quality reproduce.

Greater braking force with the same pedal force

The brake arm fits almost all Vespa Largeframe Models and is one meaningful improvement especially for all PX before 1984, as well as rally, sprint and co, because the brake arm is longer and a greater braking force is generated with the same pedal force.

Our practical conversion kit

With the Set for retrofitting every PX can be brought up to the state-of-the-art.

The solution for perfectionists with a T5 brake cable

In order to carry out the conversion, a slot must be made in the cable guide of the brake pedal. The T5 brake cable has a cast nipple at each end and can therefore no longer be threaded through the bare hole in the cable guide on the pedal. In addition, the M8 set screw on the PX engine blocks must be removed and drilled to the size of the brake cable abutment.

 

 

The simple adapter solution

Those who shy away from the effort described above can easily fall back on the variant with our adapter for the pulling thread:

If the brake cable is not to be completely replaced, we also offer a fast one Adapter solution

Conversion for Largeframe Our Oldies

For the Vespa Largeframe Models with an external brake pedal, such as Vespa Rally, Sprint, VNA, VNB, etc., can also be converted either with the adapter or with one loose brake cablethat has one end with the matching thread.

The simple installation using a Vespa PX

Here we briefly present the conversion using the example of a Vespa PX.

In order to be able to replace the brake arm, it is necessary to remove the brake cam.
In order to gain access to the cam, the rear wheel and the brake drum are dismantled.

 

cap and Sapwood remove

 

 

Dismantle the rear wheel

 

and then the brake drum remove.
ohne impact wrench is the Holding tool for Vespa and Lambretta brake drums a real help.

 

 

If the brake drum is removed, the brake shoes are freely accessible. Here it is worth taking a look at the position of the brake cam.
If the cam is almost 45 ° inclined to the brake shoes with the brake pedal unloaded, as shown here, this is an indication that the Brake shoes are soon worn out.

 

 

 

In order to be able to pull the brake cam a bit out of the guide, it is necessary to Brake shoes to remove. the Retaining rings can be removed quite easily.
However, care should be taken to secure the little nasty things against jumping away.

 

 

 

 

With a wider one screwdriver the jaws can be spread apart and removed one at a time. Shouldn't the brake shoes
are replaced, it makes sense to mark the installation position on one of the brake shoes. As can be seen in the picture above based on the abrasion,
the approaching brake shoe is subject to a different wear pattern than the decelerating brake shoe. Therefore, it makes sense to remove the brake shoes when reassembling
to put them back in their accustomed place.

 

 

After unhooking the spring for the brake arm is the Safety split pin accessible. Once the split pin has been removed, the Brake cam pulled out
become and gives the Feder and the brake arm free.

 

 

 

The brake cam is provided with a franking in which a Fat storage is introduced for long-term lubrication. Just fill up if necessary.

 

 

If the brake cam has the latest lubricant technology, the brake arm and the spring can be installed.

 

 

Do not forget the cotter pin before attaching the spring.

 

 

In this case, new brake shoes are used. To protect the guides from corrosion and to prevent the brake shoes from seizing up,
will be here copper paste applied.

 

With the main shaft as support, the brake shoes are placed in the guides.

 

 

The Mother the Lusso main shaft with SW24, for example, is fitted with a torque fastened by 110Nm.

 

 

Before cutting the old inner cable to length, check whether the Adjusting screw is on “0”.

 

The required pull length for the adapter can be determined based on the position of the brake arm. The pull should be right right up to the end of the arm
are sufficient. the Cable shears ensures a clean and safe cut without the cable fraying.

 

 

Push the adapter up to the end of the inner cable and secure it with the clamping screw. After the first test braking, check whether the end of the train
is still in the same position. If not, the clamping screw must be checked and retightened.

 

 

So that the adjusting nut on the adapter is easy to move at all times and does not corrode, a little copper paste can also be used here.

 

 

Mount the rear wheel again and the wild ride can go on.

 

Pinasco

Motor housing Vespa T5 from Pinasco

Just got us from Pinasco the news reaches us that the long-announced engine housings for the Vespa T5 should arrive next Thursday.

The engine housings of the rare Vespa PX125T5 have always been few and far between. We are all the more pleased that something is happening again with the products for the T5.

Diaphragm and rotary valve engines for Vespa T5

Pinasco now offers two alternatives. Like the PX motor housings also, it will for the T5

  • a classic Rotary valve (Master) and article number: PN26482024
  • a motor housing with Membran (Slave) give. Item number: PN26482025

In terms of price, the T5 motor housings are slightly higher than the PX variant lie.

More technical details We can only give you this when we have received the first motor housings in the next few days. We keep you here in Scooter Center Blog up to date.

Build T5 engine

The easiest way to complete such an engine is to order the appropriate engine revision kit: Engine revision set Vespa 125T5

Engine revision set -OEM QUALITY- Vespa T5 125cc article no. 3330409

Information about a super suitable Exhaust you find here Vespa T5 exhaust

bigbox-vespa-t5-bgm1012tr4

First pictures of the Pinasco T5 engine

Here are some pictures that Pinasco made available to us.

The motor housings are expected to be delivered with all fixed stud bolts and suitable silent rubbers for the motor cross-member and shock absorber mount.

 

Pinasco engine housing for Vespa

The Pinasco motor housings are very high quality replacement motor housings made of the finest die-cast aluminum. In addition to the very precise processing, they also offer many special features that are particularly interesting for tuners.
In addition to the significantly larger sealing surfaces on the cylinder base and carburetor inlet, Pinasco also offers the housing as a version with a diaphragm inlet. This suction technology, which has long been standard in the automatic sector, also offers large carburettors a good passage to breathe deeply. Further reinforcements in the cast, a larger crankshaft bearing and the great scope of delivery round off the superb overall picture of the Pinasco engine housing perfectly.

The housings are manufactured in two variants:
MASTER = ROTARY VALVE INLET (LIKE FROM THE PIAGGIO FACTORY)
SLAVE = DIAPHRAGM CONTROLLED

The engine internals and ignition components of all 125-200ccm models from 1982 onwards can be taken over. The components built from 1984 onwards are preferable due to the improved and more stable gearbox and the more powerful alternator. The motor of the COSA models is also well suited as a donor motor. Their engine block is outwardly different, but uses the same innards as the PX models from 1992 onwards.

Both versions have the same useful improvements:

  • MATERIAL
    High quality die-cast aluminum with a fine surface
  • SEALING SURFACES
    Very precisely milled sealing surfaces
  • STRONGER
    Reinforcing ribs in the area of ​​the main shaft bearing on the switch latch side and the shock absorber mount
  • SOLID
    Significantly more material in the area of ​​the cylinder base sealing surface and the carburetor inlet
  • OIL SEAL
    The housings are made to accommodate a metal shaft seal (coupling side). Please always use the version for the 200cc versions with a brown sealing lip.
  • FIT
    Two additional fitting bushes = crankshafts with an excessively long stroke can do without the centering edge of the Lima half. Dimensions of fitting bushes AØ = 9,95mm, IØ = 8,40mm, h = 13,80mm
  • RUBBER
    The holes for the large silent rubbers are Ø = 44mm (original Piaggio Ø = 43mm).
    The enclosed silent rubbers are stiffer and offer better guidance of the motor in the frame.
    Piaggio silent rubbers also fit. Solutions with metal bushing or without pre-tensioning usually do not fit if they were manufactured for Piaggio engine housings (Jockey, PLC).
  • NUMBER
    The motor housings do not have an embossed motor number or prefix
  • OIL HOLE
    No drip hole for gear oil = the nonsensical drip hole that shows whether the inner shaft sealing ring is defective has been left out *.

* Our tip: run the sealed bearing and external shaft seal with the appropriate brake drum.


SPECIAL FEATURES ROTARY VALVE VERSION
- Extra large sealing surface over both engine halves, suitable for all intake manifolds
- Can be used as a 1: 1 replacement for an original motor housing
SPECIAL FEATURES OF THE MEMBRANE VERSION
- Central, full-surface membrane inlet
- Incl. Membrane intake, incl. Membrane in RD350 format (hole 58x48mm)
- Suction rubber can be rotated 360 °, connection width carburetor = Ø34mm
- Rubber suitable for Keihin PWK28, Mikuni TMX27 / 30, Dell'Orto PHBH28 / 30, VHS24-30
- No cast-in axis for oil pump control
- No hole for oil pump drive

The enclosed fitting bush for the auxiliary shaft must be inserted by yourself
If transmission components other than those of the PX models from 125cc are to be used, please check the auxiliary shaft axis for compatibility beforehand and change it if necessary.
Please insert all stud bolts with high-strength screw adhesive. The cylinder studs are not oversized on one side, as is the case with the original Piaggio. Therefore, glue in the supplied Pinasco cylinder studs here as well. We recommend cutting all threads and cleaning them with compressed air.
ASSEMBLY NOTE:
The crankshaft bearing NU205 on the alternator side is not seated flush in the engine housing.
It protrudes approx. 1mm towards the crankshaft.

DELIVERY

· ROTARY VALVE
- All studs
- Silent rubbers + washers for silent rubbers
- Housing seals
- Bushing for auxiliary shaft axis

· MEMBRANE
- as above, additionally included:
- Intake manifold including membrane, suction rubber, seal and small parts

Mufflers and exhaust systems

Exhaust systems rear silencers

In our ScootersYou will not only find hop for exhaust systems specially designed for your scooter, but also for individual ones rear silencer and exhaust accessories.

Why is it needed on a scooter?

The silencers on or in the exhaust of your scooter are used to reduce engine noise. Rear silencers are located downstream of a possibly built-in catalytic converter: END silencer -> mounted at the end. Especially with the 2-stroke engine, the exhaust silencer has a decisive influence on the engine characteristics.

Mufflers and exhaust systems

Buy sport exhaust

For a few years now, vehicle manufacturers have been making a little more effort and installing sportier-looking exhaust systems from the factory. Nevertheless: what we scooter drivers usually want is the personal customization of the scooter, which is why sports silencers or entire sports exhaust systems are on popular tuning product.

Typically, these popular plants offer one sportier exhaust sound and higher quality material, quality and better look. You will mostly be using a EC type-approval offered and are therefore often free of registration, but then do not bring more performance. Real sports exhaust systems are different, with the other engine components being adapted accordingly significant increases in performance expected. These are then only for the racetrack or have to be individually approved and entered by the TÜV.

Sports exhaust racing scooter

The BigBox trend has been around here for some time. Real sports exhaust systems in the original look. Here we recommend the bgm PRO BigBox for Vespa as a sport or touring version and the Big Box Lambretta.

Mount the exhaust system / rear silencer on the scooter

The assembly is usually carried out at the original breakpoints on the scooter. The exhaust should match the engine and the desired driving characteristics (e.g. high torque = power for city and travel). Usually the engine has to be adjusted to the new exhaust system. Ignition timing and carburetor adjustment should be checked and adjusted. Ignition adjustment tools such as the WAL (Classic Vespa), the BELUGA (Lambretta) and one are suitable here Ignition gun and Nozzle sets.

Repair dampers / new insulation

If insulating wool is installed, it can dissolve over time. We offer Exhaust insulation wool with which you can re-insulate the rear silencer.

Vespa touring exhaust

The steam hammer

The BGM Big Box Touring is the touring steamer in our program.
Developed for full thrust from the lowest engine speed range.

An early entry into performance As well as the significantly increased torque make the touring version of our BigBox the ideal companion for everyone who likes to travel as a couple or with a lot of luggage. Trailer drivers can also look forward to it. The high available torque makes the otherwise mandatory reduction of the reduction unnecessary!

Vespa touring exhaust

 

On a standard PX200, the touring box gets on 300 rpm earlier than the previous king of all touring riders, the standard exhaust. This exhaust is also in good hands on powerhouses like the Polini or Malossi sport cylinders.
Just like the original Vespa exhaust, the BigBox is natural also double-walled and provided with insulating wool.

Vespa touring exhaust

The BigBox Touring

  • Original optics
  • Quiet thanks to the double wall and insulation wool like the original exhaust
  • High torque
  • No performance hole
  • Speed ​​range like original
  • Very unobtrusive
  • Also fits rally / sprint without modifications
  • Solid construction with clamp on the cylinder
  • Handcrafted in Europe

EASY INSTALLATION

The exhaust is mounted like the original exhaust. The elbow is attached to the cylinder using a clamp. Compared to loose fastening with an O-ring seal, this results in the best stability and prevents damage to the outlet flange. The elbow has spring tabs. To ensure optimum ground clearance, a spacer that is too short should not be used on the rear shock absorber.

Vespa touring exhaust

OUR TIP

With a longer gear ratio, the available speed range can be stretched enormously in each gear. This means that the high torque can also be converted into high speed.
Ideal: just that BGM Superstrong clutch with 24 tooth pinion install (original 23 teeth). Works without otherwise having to change anything on the engine and results a plus of ~ 5km / h.

Motors with an abundance of torque can do the longer BGM primary gear with 64 teeth Use in combination with the 24 tooth clutch (+ 8km / h).

CONCLUSION
A lot of steam at a low speed - yeah!

Vespa exhaust bgm BigBox Sport put to the test

Michel Holden from England, long-time customer of Scooter Center, visited us briefly on his way to the “Ferien im Sauerland” run and seized the opportunity Vespa Aupuff BigBox Sport to test once on the test bench.

05_2015 001

Vespa PX 200 with Malossi 210 and PHBH 30 carburettors

His scooter, a German Vespa PX200, which he bought when he was stationed with the British Forces in Germany.

The engine is quite simple and consists of an "old" Malossi 210 cylinder, DellOrto carburetor PHBH 30, Mazzucchelli racing shaft with 57mm stroke and a Taffspeed MK4.

In England on a Dynojet, Michael tells us, the engine had this configuration before he left 17,8BHP (Brake Horse Power), i.e. performance measured on the rear wheel.

This is a useful reference value for our input measurement, because it allows us to assess whether the engine has lost power and how comparable the measurements are.

The old “two-decade” with the MK 4 also delivers the predicted performance well. Since the value determined on our test bench only deviates by a few tenths, one can say that the measurements on the Dynojet and here in our case are comparable in this case.

 

M. Holden Malossi 210 PHBH30 MK4

The 90s: and Taffspeed MK4 Vespa exhaust

The MK4 was a good one in its time (in 1996 we sold the first systems with TÜV approval in Germany) All-rounder with a useful performance curve in such a way that there is good performance before the actual use of the resonance. In general, it can be said that an engine that develops an output of at least 5000PS in the range of around 10 rpm and increases the output and torque as the speed continues to increase, is perceived as being “easy to drive” on the road. With just under 18Nm in the range just before 6000rpm, the MK4 is also a candidate on this engine, which often prompts the driver to shift down when a little more acceleration is required in fourth gear at less than 90km / h.

The modern racing exhaust: bgm PRO BigBox Sport

At the time of the MK4 the exhaust was the state of the art and no exhaust that was optically close to the original “lunch box” would have come close to such performance values.

For some time now, however, the development has been moving in the right direction efficient exhaust systems, which are optically as close as possible to the original.

The BigBox was also created from this specification:

To combine the performance of a resonance exhaust system with the look of an original exhaust system.bgm tuning

BigBox Sport vs Taffspeed MK4

Here in a direct comparison the BigBox Sport and the Taffspeed MK4.

 

bbs mk4

Compared to the MK4, the BigBox Sport can operate in the range from 4500rpm significantly increase in torque and power. A direct comparison on the road makes the scooter look more drivable because it is simple more torque for acceleration Available. Especially in the range from 5500 rpm, when the scooter is being driven on the expressway or motorway, the additional torque when overtaking has a positive effect.

Michael was so impressed with the BigBox Sport that we weren't even allowed to unscrew our test specimen from the test stand from his scooter and he continued on his way to the Sauerland directly with the BigBox Sport.

New Vespa touring exhaust

Today we have the first Manufacturing sample the BigBox Touring for the 200 Vespa PX engines.

The normal process of a sample test includes, in addition to evaluating the appearance and fit, runs on ours Scooter Center P4 dynamometer.

As we did in an earlier one Contributions to this Vespa exhaust have already noted, the BigBox Touring is significantly more delicate in the manifold area than its big sister, the Big Box Sports.

BigBox P200_2

Without her black, heat-resistant garment the BigBox Touring looks a bit bare. But we also attach great importance to taking a close look at all the connection points without a “top layer” during a sample test.

BigBox P200_3

Test assembly on Vespa Sprint with 200 engine

One of the first tests was assembly on one Vespa VLB (Sprint). In combination with a 200 PX motor, such conversions often lead to space problems. Especially in the area of ​​the main stand, especially the “U's” and the tabs for the stand springs. The stand feet may also collide with the manifold, depending on the routing of the exhaust system.

With the BigBox Touring, we made sure that these bottlenecks are sensibly defused. Even with vehicles with the only two-spring system on the main stand that has been introduced for the German market fits the BigBox and the stand feet are at a safe distance to the hot manifold.

BigBox P200_4

The Big Box Touring Just like its big sister, it is equipped with a solid clamp and additional holders for exhaust springs.

If you want to be on the safe side at this point, then this is ours Retaining plate with 2 exhaust springs exactly the right accessories for your BigBox.

Performance measurement Vespa exhaust

If we like the look, workmanship and fit, then it goes to them Performance measurements.

Our first "test victim" is a Cast iron Polini with 207ccm, SI24 carburetor on a standard Vespa PX200 engine.

 

big box touring 200

Early torque for everyday use and touring

When developing the BigBox Touring, we made sure that the possible torque is available very early and that the exhaust has a lot of pressure from the low revs.

The earlier and more homogeneously a motor delivers its torque, the more pleasant it is Everyday driving. With the BigBox Touring, you can already step in on our test engine with the good, old gray cast iron Polini 3900rpm over 18Nm Forward. Converted to fourth gear, that means a pleasant one Cruising at 50km / h with a very good potential to accelerate through to the top speed.

 

Longer translation possible

Depending on which engine you are using the BigBox Touring on, a longer primary reduction may be required makes perfect sense can be used to drive a little more revs at the same cruising speed. The easiest way to extend the reduction is with a clutch pinion. That bgm clutch pinion for the Cosa type clutches or a durable solution like ours bgm Superstrong clutch are good and loyal companions here. Due to the longer reduction, up to to 5km / h more top speed at the same speed is possible.

Performance like a Vespa racing exhaust - Looks and acoustics almost like a standard exhaust

BGM1011SP (1)

Purebred Vespa racing exhaust

The BGM BigBox Sport is a thoroughbred racing exhaust, in the unsuspicious design of an original exhaust. It positions itself as a clear alternative to eye-catching and mostly loud and large resonance exhaust systems. the high motivation clearly sets it apart from other boxing systems. Designed for performance-oriented drivers who appreciate the benefits of an inconspicuous vehicle.

The performance potential of the BigBox SPORT grows with the engine concept

Like any good racing exhaust, the Sport Box requires a powerful engine concept in order to be able to develop its full performance. Around cylinders like that Polini 210, Malossi MHR and Co. it offers impressive results. See performance diagrams from test runs on our in-house Scooter Center Dynamometer further down.

It also supports engine outputs above 25PS without any problems and pushes ahead with full torque. Despite their high peak performance the Sport Box rises with one early high torque and also enables comfortable driving.

Due to its consistent design for a high gas throughput, the BigBox Sport is not intended for use with near-series engines or tame tuning cylinders. It needs a clear and powerful discharge impulse to get the large volume and the thick elbow to fill the Sport Box with life.

PRO:

  • Original optics
  • Top performance like a resonance exhaust
  • No performance hole
  • Broad speed range
  • More top speed
  • Very unobtrusive
  • Also fits rally / sprint without modifications
  • Solid construction with clamp on the cylinder
  • Handmade in SPAIN

CON:

  • Not for vehicles with 8 inch tires (ground clearance too low)
  • Not for near-series engines

Fixing and assembly

The assembly is easy. The elbow is attached to the cylinder using a clamp. The sealing is done for the different outlet pipe diameters in the 200cc models by insert plates. Compared to a loose fastening with an O-ring seal, this results in the best stability and prevents damage to the outlet flange. A long spacer on the rear shock absorber could be used for even greater ground clearance.

And finally ...

Pure understatement. Performance like a racing exhaust, optics and sound similar to an original exhaust.

Depending on the engine concept, the BigBox, just like a resonance exhaust, can significantly increase performance.

BigBox SPORT on 12PS Vespa PX200

Even as a classy racing exhaust, the BigBox SPORT can mobilize more torque on a 12 HP original Vespa engine in the upper speed range. In comparison here against an old friend, the Sito Plus. But then things really get going on a tuned Polini or Malossi engine. See below.

With main stand

Of course with the PX but even with Vespa Rally, Sprint, GT, GTR models the main stand still fits!

To accommodate the manifold length on the vehicle was not really easy, it took us a few tries to find a course that was as close as possible fits many vehicles and does not collide with the main stand or the footplate.

With the Rally, Sprint, GT, GTR models, the distance to the stand feet is often critical in connection with a 200 engine. With the BigBox Sport, we made sure that there was enough space here and on the main stand.

BigBox Sport 200

Maximale Bodenfreiheit

Although the BigBox lives up to its name due to the design, we also took the appropriate ground clearance into account when laying it.
As usual with the Largeframe Models, as a rule, only have the kick starter screw and the gear shift in contact with the road.

bigbox sport 125 005

However, we have to advise against using the BigBox Sport for the 200 cc on vehicles with 8 ″ tires.

Please check the clearance of the elbow to the footplate and the roadway. In individual cases, you can still correct this with a longer spacer on the rear shock absorber.

We are working on the touring version of the BigBox for those who love engines that deliver their torque at low speeds. This will then also be suitable for the 8 ″ models.

The bgm BigBox Sport is a thoroughbred racing exhaust, in the unsuspicious design of an original exhaust. She positions herself as better alternative to conspicuous and mostly loud and large resonance exhaust systems. The high level of motivation clearly sets it apart from other boxing systems. Designed for performance-oriented drivers who appreciate the benefits of an inconspicuous vehicle.

Around cylinders like that Quattrini M1X and Co. it offers impressive results. It also supports engine outputs above 25PS without any problems and pushes ahead with full torque. Despite its high peak performance, the Sport Box gets in early and also enables comfortable driving.

Not for series or touring engines

Due to its consistent design for a high gas throughput, the BigBox Sport is not intended for use with near-series engines or tame tuning cylinders. It needs a clear and powerful outlet impulse to fill the large volume and the thick elbow of the Sport Box with life.

Due to the significantly increased volume and a new manifold, the BigBox Sport is a powerful companion for engines with sporty characteristics.

Development and test runs

Among other things, an engine with an LML membrane, a 24 SI carburetor and a 60 bgm crankshaft served as a test victim.

In addition to one Polini 177 we also have an unedited one here Quattrini M1x plugged onto this engine.

Despite the small LML membrane with the thick steel plates, the Polini 177, which is known to be rather tame, develops a remarkable curve.

To something more overflow duct and outlet area, the BigBox Sport reacts as expected - here in direct comparison with a Quattrini M1X on the same engine.

When relocating the new large manifold, we looked for the best possible way so that there was enough space for the roadway, frame and main stand, which was not so easy with the dimensions of the new Vespa racing exhaust. We needed some stencils, samples and test systems so that the process now applies to almost all of them Largeframes fits.

The development of the new Vespa exhaust

From the first prototype (left) to the finished, tested and approved exhaust,

bigbox sport 125 006

it was a little further way ...

However, we also made sure that the bgm PRO BigBox Sport, sits correctly despite its dimensions. Especially with the Vespa Rally and Vespa Sprint models
it is quite difficult, due to the chassis geometry, the position and the distance of the main stand to the engine, one good course a DAK Bungalow.

Copy of bigbox Sport 125 002

However, we definitely recommend for Vespa Rally / Vespa Sprint and similar models to check the distance to the road and maybe a little longer distance piecek to be used for the rear shock absorber.

We have to exclude the use on the Vespa models with 8 ″ tires on our part.

Vespa bgm PRO BigBox Touring

Of course we also looked in another direction:

So that you can use an original cylinder from Pinasco, DR or a PX150 can also take a BigBox for a walk, we are currently doing one Touring variant of the BigBox to develop. We have focused on an even earlier performance and torque entry. The BigBox Touring is also available on the Vespa Largeframe Models with 8 ″ tires can be used.

Easy assembly of the Vespa exhaust

For assembly, you should lightly grease the O-ring so that it is not damaged on the edge of the outlet connection. Fig.11 002 With the PX125 cylinders, the top, rectangular cooling rib is ideal to take on the role of the spring holder. Provided with a hole of 4-5mm, you can easily hang the springs here. Fig.11 004 By positioning the springs in this way, you can ensure that the connector is always pulled towards the cylinder and thus seals perfectly. With the T5 variant, assembly is even easier: You can simply hang the springs into the loose flange plate and ... Fig.10 006 then simply screw it together with the socket. Fig.10 009

Vespa exhaust with full power!

With the T5 variant, we have also done a few runs on our test bench for you. Our engine is with one Polini 152cc cylinder equipped. All other components correspond to the series. Here is the direct comparison between a Piaggio T5 exhaust and the BigBox versus power / speed. Fig.12 004 The BigBox also gets on the T5 engines a little more gently and then increases significantly at higher speeds when power and torque are required to overcome the increasing driving resistance. To make things clearer, here is a gear overlap against km / h Fig.12 003 Piaggio exhaust black, aisle 3; green gear 4 BigBox blue, aisle 3; red gear4 It is easy to see that when accelerating in gear 3 from approx. 60km / h more torque and power is available. At the switching point to gear 4, between 80 and 85 km / h, the Bigbox is 2PS and 1,4Nm more available. At 100km / h, 2PS and 2Nm more are available to overcome the driving resistance.

Vespa Big Box with M1X

We saw a very impressive diagram from Moritz for the PX engines. On one Cylinder QUATTRINI M1X 172 cc With significantly higher control angles, the BigBox delivers very good values ​​compared to a real resonance exhaust. Here is the blue curve. Pots

After Andreas had done his “homework”, not only we were very impatient and excited to see the result.

Due to its power delivery, it can be used universally on original as well as heavily tuned engines at home.

First pictures:
Here are the images of the prototype. The exhaust will be available for the following models:
- Vespa PX 200 / Vespa Rally 200
- Vespa PX 125 / Vespa PX150 / Vespa SPRINT etc.

We expect the exhaust from the beginning / middle of summer and are really looking forward to it. The test drives were great.

Test run performance diagrams:
The exhaust systems were made on the professional Scooter Center Ammerschläger P4 test bench tested with laboratory software:
Result: Significantly more power! eg:

  1. + 2PS more on PX200 compared to the original exhaust with significantly improved revving = top speed
  2. + 3PS more on Malossi 210 compared to comparable road exhaust systems
  3. + 5PS more on Malossi 166 (60mm shaft, exhaust made, 28mm carburettor on rotary valve) opposite Vespa Road exhaust

As the Test roller the following candidates were available:

The test runs were all done with the engine warm. The tests were carried out against the existing exhaust systems on the vehicles and against the SIP Road exhaust.
Almost all scooters were then tested for several kilometers on the road in order to really feel the change. That was the very subjective so-called Popometer test ;-)

The conclusion
Awesome part - this is how a Vespa exhaust has to be!
Both for the "laboratory test" with performance diagram and for subjective testing on the road:
The new bgm PRO exhaust puts you in a good mood. The engine turns out much more freely, the Vespa becomes much more flexible and faster and without the consumption or volume increasing noticeably.

Vespa BigBox Vespa exhaust

Development of a new Vespa exhaust system - the Vespa BigBox from Scooter Center

After we and Mark have brought the Lambretta BIG BOX so far that we can only wait for the manufacturer and, at most, issue reminders, we sent a few sets of PX exhaust shells to Doncaster.

Mark has all of his ideas regarding PX BIG BOX implemented directly after the Eurolambretta. On Monday morning the PX 200 BIG BOX was finally here in the store. A few minutes later the test bench computer started and the games could begin.
