It all started with the decision to choose an exhaust for the 1000km trip of our GTS Keyless 2023 and we went for the Malossi.

We took the opportunity to stop off in Bologna to visit Malossi on the way to the Pontedera Vespa World Days, where I was able to see what is behind the brand, and it is impressive, all the scooters were beautifully presented in an enviably clean workshop, and walking around the huge site we even picked up our order on the way to Germany, making us feel at home.

There we were invited to their event, the timing of which coincided perfectly with our return of the VWD to Germany, this time in Modena. The event took place on 21.04.2024 at the Autodromo di Modena and consisted of two main parts:

Miscela Day

Some of the things we found at this meeting were the Dyno, dj set, Contest of ugliness and arrogance where the only rule is to be yourself, a simulator: Moto trainer and a pit walk to make the speed experience closer, the shop, food and drinks, and even a tattoo area with flash designs by Malossi.

It's amazing how the atmosphere of speed and performance is in the air, an event that left us amazed and with a wide participation, from children riding their bikes on the rear wheel, to the most professional on the track, to those who bring their uniqueness scooter designs to show them off to the connoisseurs.

Malossi trophies

in the 37th edition, we had the opportunity to live closely the experience of a scooter race with Joe Shack, all the tension before and after the race, the physical and mental preparation and the support of a great team, which together, will define results in the seconds that these races last.

In the boxes you could also find it Malossi Racing Academy with the Italjet Dragster 200cc.

in short, an event that speed lovers have to experience once in their lives.

Vespa always puts on a colorful and well-done trade fair appearance. The new colors for GTS, Primavera and Sprint fit the picture well. Which can also be customized with a number of decors and color and finish details in the Vespa configurator.

Overall, Piaggio's Centro Stile didn't let up and worked hard on the finish, introduced new materials and tinkered with the details. Especially with the Vespa Primavera and Vespa Sprint S models. Quite obviously on the steering head, which has new handles as well as new switches. The inside of the leg shield is now much easier on the eyes.

The Vespa Primavera comes with a new logo on the fender, so it will be interesting to see whether this catches on.

The tech version of the Primavera also features the keyless start system and the TFT instruments through which the functions of the Vespa MIA multimedia platform can be controlled. In the other versions, the analogue/digital speedometer has also been redesigned and equipped with LED lighting.

Vespa Primavera and Vespa Sprint S are available with state-of-the-art Euro 5+ engines with 50, 125 and 150 cc displacements with three-valve control and electronic injection.

The Vespa Elettrica will be replaced by the electric versions of the Vespa Primavera and Vespa Sprint S. The range is given as 125 km in Eco mode and there is a 45 km/h and a 75 km/h variant.

The new rims are also interesting.

It will be exciting to see whether Vespa has any news up its sleeve that will be presented at the Vespa World Days 2024 in Pontedera.


Andrea Pinasco sold the traditional company to Betella in 1999, but they continue the tradition convincingly. Traditionally, there is a colorful array of new products here every year. Like the PX cylinder with the new and popular displacement class of 244/252 cc. Although the one from last year doesn't seem entirely unfamiliar to us.

It's always nice to meet friends and that was when Scooter Center-Team on the EICMA 2022 the case. Here is some news that caught our attention:

New Vespa models EICMA 2022

Piaggio proudly presented the new 2023 model years, which will win many new fans with some new, visible and invisible features. 
The most prominent model is of course the GTS300.
We can already say in advance: It drives better than ever! Piaggio has finally dedicated itself to the subject of chassis and has now made it much more stable and active. This is accompanied by a new front wheel suspension including a new supplier for the brake components. Nissin from Japan is now on board here and is responsible for a befitting delay. The front shock absorber of the GTS models differs again from the previous models, which brings us to the third stage of evolution. Interestingly, Piaggio has retained the previous fork/brake type for the new GTV models (recognizable by the headlight on the fender). In line with the spirit of the times, a keyless go system has now been rolled out on the GTS/GTV platforms. With that, the conventional key is history. It was replaced by a pure transponder (key fob) that can be used to start and unlock the vehicle when approaching via a rotary knob in the position of the former mechanical steering lock. The engine corresponds to the Euro5 engine which is already known from the previous model years. The models generally known as HPE, which brought a decent increase in performance compared to the Euro4 models, are used unchanged, i.e. with full power (23,8 hp at 8.250 rpm), in the 2023 models. 

Externally, the new GTS models can only be distinguished from last year's models with a trained eye. However, Piaggio has hardly left a part untouched, so that the term facelift at this point would not do justice to Piaggio's effort. The clear identification feature of the GTS300 Bj.2023 are the switch units separated from the handlebars and the slightly exposed license plate light. The well-known division into GTS, GTS Super, GTS SuperSport and GTS SuperTech has been retained. While the first three versions are more to be understood as color variants, the SuperTech models also stand out technically with a large TFT display instead of the classic instrument landscape. In order not to lose touch in times of mandatory constant communication, Piaggio offers its new connectivity system MIA as an option. A concession to activate new target groups and to give the vehicle class further features, away from the purpose of a pure means of transport. Certainly a good idea to be able to place the GTS models even more fully and comprehensively on the market. 

Vespa 946 10° Anniversary

The famous 946 models were also presented in a new guise. Always designed less as a technology and more as an image bearer, the 946 is both extroverted and a homage to the company's own history. The fact that with the 946 models Piaggio has strayed very far from the original idea of ​​the simple but robust everyday vehicle is not at all an issue here. On the contrary, the 946 embodies that archetype scooter that any child would paint. This is more than any marketing department of other manufacturers even dares to dream of. Appropriately, Piaggio has dipped the 946 in a beautiful shade of green that is distantly related to the first paintwork of the models from over 70 years ago. In contrast to the GTS models, the 946 models therefore appeal more to artistic finesse, to whom an individual vehicle concept means more than explicitly good driving performance. For this reason, Piaggio has not yet given the 946 models a keyless go, but still relies on the good old key technology. To compensate, it has a modern LCD display and an LED headlight. The 946 models are offered with 125cc and 150cc.

 Vespa GTV

The new GTV models have undergone major visual changes than their GTS brothers. The handlebar fairing as well as the handlebar itself have been completely redesigned. Together with the sports seat including the new cover made of plastic (screwed/removable) and the decorative stripes, a beautiful nostalgic race look is offered, almost retro sport from the factory. With the front wheel fork, Piaggio stayed with the previously produced type so that the retrofit parts (shock absorbers) already available for these models also fit. However, keyless go is also already on board here and makes the GTV a reliable and easy-to-use commuter with a touch of avant-garde. The USB connection, LED headlights and the digital speedometer round off the picture of the modern oldie perfectly.

GTS Supersport 300 HPE ABS ASR

New SpecialModel: Primavera Color Vibe 

The color vibe special models of the Primavera models impress with a modern appearance that Piaggio has created with a simple but very effective trick. A completely different vehicle line is implied by a horizontally applied decorative color tone, which deliberately contrasts strongly with the rest of the vehicle paintwork. This makes the Primavera models appear much sportier and more pleasing. Attached to the side, the engine displacement is also a nice gimmick. The color vibe models are available in 50cc, 125cc and 150cc versions.

Vespa Primavera Color Vibe 125 i-get ABS 


Pinasco is still busy and always inspires with new products. The latest hit is the 244/252cc cylinder which was designed for a standard engine housing. Undoubtedly, the already legendary Quattrini M244 was the inspiration here, with its huge success in 2015 no one expected would have; Too expensive, too exclusive. Pinasco has now also dared to interpret the topic of maximum cubic capacity for the series housing. Here, too, a cylinder is used that no longer has a cylinder base that has to dip into the motor housing. This allows the size of the cylinder bore to be increased to a whopping 72mm (series 66.5mm) without having to rework the engine housing. However, a crankshaft with a significantly longer connecting rod (130mm vs. 110mm series) is absolutely necessary for this, as the channels are located significantly further up in the cylinder. A big difference to the Quattrini M244 cylinder is the intake control. The Pinasco cylinder has a large cylinder inlet which is fired by an intake manifold with a membrane. This makes you completely independent of an intake control via the engine housing. Pinasco will offer matching crankshafts with 60 and 62mm stroke. The connecting rod length is 130mm. According to Pinasco, if a Pinasco engine housing is used, there is no need to spin the crankcase for the crankshafts. This step would only be necessary for original Piaggio motor housings.

The cylinder with side outlets is also shown here. These are probably omitted in series production.

Pinasco Eureka

A special feature at the Pinasco stand was the E-conversion kit for the Vespa, dubbed Eureka Smallframemodels.
The solution patented by Pinasco envisages replacing only the crankshaft and the cylinder. The cylinder is replaced by an electric motor with a vertical output shaft. The replacement for the crankshaft, on the other hand, absorbs the power of the engine via spur gearing and transmits it conventionally to the clutch. The scooter can be operated as usual (coupling, shifting, accelerating, uhh, giving electricity).


New ECU for GTS 300 Euro 5

Polini offers a new cylinder kit including ECU unit for the GTS300 Euro5 models. With this, the injection quantity/time can be adjusted within a certain framework to the installation situation (modified exhaust, air filter, etc.) by simply adjusting a potentiometer.

New exhaust Vespa Sprint

Polini now also offers their popular 'original box' exhaust system for older engine generations such as the Vespa Sprint. With these models, the exhaust is only fixed to a screw on the engine block. Polini has therefore modified and strengthened the bracket. The end tube was also lengthened. This appears to be smaller than in conventional systems. As soon as we have the new systems in the program, we will mention this detail in the shop. It is also unclear whether the main stand of the Sprint models can fold in unhindered. An often voiced point of criticism of the previous Polini systems which were used on the Sprint/Rally models. Apparently Polini only offers the modified exhaust for the small engine blocks (125-150cc).



New Lambrettas

Lambretta celebrates its 75th anniversary at EICMA 2022. It is presented with a modern range in different shifts and trendy colors.

Sport Scooter Dragster 500 GP

Italjet presented its new GP500 model to the public for the first time at the EICMA 2022 and shows that motorcycles and scooters are getting closer and closer. A full 450ccm with 43 hp and a six-speed foot switch were paired with a squat and very attractive-looking raw frame including scooter-typical fairing and, for the range of services, rather small tires. According to Italjet, the GP500 should be fast at a whopping 185km/h. For us a real cracker that could certainly take on the legacy of the Gilera Runner 180.

 and some more italjet beauties

The next date for the  EICMA 2023 is here, we're excited to see what next year brings.

Part 5 for stage 4

Fortunately, as with so many things in life, everyone has their preferences...
More RPM and more peak power or more torque at low RPM.

That's why in today's part I'm looking for more... But not top performance, but for speed range and torque. The "tractor engine" is sought.

In part 4 with stage 3, I looked in the direction of the higher control angle by raising the cylinder and making a small adjustment to the exhaust. If I were now to increase the exhaust further in order to perhaps achieve higher peak performance and speed, the way would be backwards; to try the cylinder with more blowdown at lower control angles installed.

So today I lower the cylinder. Overall, this results in lower control angles, but the pre-release increases slightly. The smaller transfer angle should allow the cylinder to produce a little more torque at low rpm.

The spacer on the cylinder head was changed from 1mm to 3mm compared to the third construction stage. At the cylinder base, the 2mm spacer leaves the field and the cylinder is only supported by a normal 0.3mm thick gasket. The squeezing edge remains at 1.3mm, as with the other construction stages.

In the following graphs are the current curves of construction stage 4 RED to see. The curves from the previous stage three appear in BLUE.

Elron is the first to show what he thinks of the change.

As can be expected, the absolute top performance drops slightly, but the maximum performance and torque shift in the direction of lower speeds. The torque increases slightly and feeds the range between 5100 and 7000 rpm.

The Polini box, which is more intended for engines with less transfer time, is placed next on the exhaust port.

At first glance, the curves may seem sobering. On closer inspection, the Polini Box turns out to be a real torque animal. At the end of this series of tests, it will rank second in terms of torque with 37.4Nm. The graph already passes the 4700 hp mark at 20 rpm. The maximum power shifts by an impressive 1000 rpm in the direction of a lower speed, culminating at 6400 rpm. The maximum torque pulls at the rear wheel at 6000 rpm. An engine constructed in this way is just begging for a long gearbox.

This allows the M244 to move over the asphalt with extreme shift laziness. Jack off the stand, shift into gear 4 and just pull the cable. Don't worry, it will be quick...


The aged all-rounder in the field.

The JL left arm puts its torque in the range between 5000 and 7000 rpm and thus offers more drivability. Although the peak power falls by one hp, the JL can still offer very good drivability in the field of resonance exhaust systems.

New Line

The handwork from the north is also responding to the adjustments as expected. Already at 5000rpm, 20 horses are ready to move significantly. Full torque is available at 6100 rpm. Although it pushes the absolute top performance down a bit and the Newline gives up 2 horses in favor of the early torque, it is happy to take the larger pre-release in order to go over 10.000 rpm and maintain it there with over 20 hp.
The Newline behaves here almost like a box exhaust system, seasoned with a significant torque kick.

Posch Nessi

The sea monster ducks its head slightly due to the reduced steering angles. But that's not bad at all. As with the Newline, the rev range shifts slightly towards early revs and develops more torque in the process. At 5200 rpm the curve already exceeds the 20 hp mark. The slightly increased pre-let helps the Nessi to a wider speed range.

Posch Racing Resi

The lush Resi handles the steering angle that is unsuitable for you amazingly well. Although it also loses peak performance, it gives an idea of ​​the bandwidth that can be possible with the appropriate control angles and more forward airflow. With a speed range of almost 4100 rpm, it is in the top league here.


The Lakers, made for a lot more alert, don't like the slack head angles that much. The exhaust craves for larger time cross sections. The speed range shifts to lower speeds as expected, but the low time cross sections are not the right playing field for the Lakers. But his chance will come with the following expansion stages...


Here again all maximum values ​​in the overview

In the fourth part of our little blog series we make the following changes to our test engine:

The cylinder is attached at the foot with two 1mm Spacers increased by a further 2mm compared to level 0.5. This changes the steering angle of the transfer channels from 124° to 126°. The outlet is adjusted to a control angle of 190° by milling. To do this, the outlet in the cylinder was raised by 1.8mm. The outlet width remains unchanged at 57%.


The first attempts are made with the Elron


A little more nervous exhaust systems would show a clear shift in the direction of performance with the changes made, but the Elron is almost unimpressed by the specifications of the cylinder and retains control over the characteristics of the engine. A slight increase in the maximum values ​​after the decimal point only indicates that the Elron has noticed that the cylinder is sending a clearer signal through the exhaust. However, the maximum torque remains at the same level as in the first construction stage.
The available speed range is reduced by 500 rpm to 3540 rpm.


Polini box


As a box exhaust, the Polini exhaust system reacts more as expected. Similar to the Elron, the can from Italy only shows small reactions. The lower effective compression makes the curve dip a bit in the rise between 4000 rpm and 6200 rpm. The system converts the slightly increased time cross-section at the outlet window with a gain of just over one horsepower at peak.
The maximum torque remains the same at 35.2Nm and is only shifted by a few hundred revolutions in the direction of higher speeds.
With a bandwidth of 3800 revolutions, the Polini system is slightly behind stage 2, but this test shows that the box does not necessarily prefer the very small steering angle. In a direct comparison to stage 1, the bandwidth and maximum values ​​have increased significantly.




JL left hand / JL performance


Our test subject had a short break in the previous construction stage due to appointments away from home; but now plays again in the third construction stage. So here is the comparison between levels 1 and 2.
This also shows how clearly an exhaust can behave when it is operated from other steering angles. The JL, which is considered good-natured, turns out to be a very approachable partner in the search for performance.
At the top, the JL provides almost five and a half more horses and climbs over the 36PS line in the graph. The torque remains at 32.6Nm at the same level as in the first attempt. However, the torque extends over a much wider range - beyond 7000rpm. The performance peak is reached with 36.4PS at 8400rpm. The JL falls below the 25 HP line considered in the bandwidth only beyond 9600 rpm and can therefore not be described as a lazy speed. In general, the graph shifts significantly in the direction of higher speeds. With a bandwidth of only 3400 revolutions, the JL even lags behind the Elron and brings up the rear in terms of bandwidth in this construction stage.


Scooter and Service Newline


The edgy powerhouse from the north feels really comfortable in this expansion stage and takes two best values ​​with it.
There are no notable changes in the rise in the newline, but it does quite a bit due to the larger advance angle in the engine speed range. With 37.3Nm, it takes the top position in terms of torque in the third construction stage. The available speed range is narrower compared to the previous tests, but here too the Newline achieves a range of 4000 revolutions. With these values, considerations germinate after a longer primary with 24-60 ...




Like the Elron, the sea monster from Posch Performance is not quite sure what to do with the changed control angles. Maximum torque remains the same and peak power increases by one horsepower. While the Nessie was still way ahead in level 1 with 4300 rpm in terms of bandwidth, the available speed range in level three is a bit on the dip station and is in the upper midfield with 3700 rpm.




Racing Resi


The Racing Resi taste the changes better. Rather devoted to the higher control angles, the Resi develops one more horsepower at the top and adds torque, which hardly affects the bandwidth on the 25hp line. In absolute terms, the Resi holds the position of the highest peak power with 38.9 hp in this level. We are slowly approaching the 40hp mark with the expansion stages.






With 126° to 190°, the Lakers are not yet playing in their comfort zone. Although it also clearly converts the changed control angles into performance. With 38.4 hp at the top, it is only just behind the Resi. With a speed range of 3700 rpm, which already extends to 10.100 rpm, the Lakers shows where the journey can go with suitable peripherals.

Here is an overview of the results. Best values ​​are highlighted in green.

M244 Quattrini cylinder Vesoa on the test bench

Quattrini M244 king shaft - the super tourer in the second expansion stage "outlet" M244_2

M244 - part 3

Im second part this Series we simply adapted the cylinder and the engine housing to each other and put the cylinder on the engine without further processing "Plug & Play".

This resulted in very moderate control angles:

  • reported 124 ° transfer angle
  • and 177 ° outlet angle

Some exhaust systems get along well with these short steering angles and thus provide quite astonishing performance.

On the other hand, the exhaust systems, which are trimmed more for performance, require larger steering angles.
In the course of the test series, the character of the performance curve of one or the other exhaust system will change.
Therefore we remove some material from the M244 in the exhaust duct and set the upper edge of the exhaust to 182 °. The outlet width remains unaffected and remains at a chord dimension of around 57%.

As a spacer, we use 1.5 mm on the cylinder head and the cylinder base plus a 0.3 mm seal on the cylinder base. This means that the control angles remain at 124 °:

  • 124 ° transfer angle
  • 182 ° outlet angle
  • 57% tendon size

Cylinder cooling hood for the long M244 Quattrini

In the meantime we have also received a matching cylinder cooling hood from GRP specialist BSK. You can find the blog here -> QUATTRINI GRP CYLINDER HOOD



The Elron uses the larger steering angle rather cautiously. With a 1,7 HP increase in peak performance, a slight loss in torque and a little less band due to the 300 rpm later entry, the exhaust shows that it takes note of this requirement but does not yet represent the right playing field for the concept . However, the Elron takes this very calmly. Presumably, the exhaust will deliver a very pleasing performance curve even with significantly different control angles and thus the concept does not completely submit to the dictates of the control angle.

Test bench diagram as PDF:  M244_1_2_ELRON


The Polini Box reacts very clearly to the small change in the outlet and provides a lot of power. The box adds over 3PS and not quite 1 Nm. The speed range is even wider by 700 rpm, whereby the graph does not even pass the 100 hp mark at 25 rpm until 5.500 rpm later and the output lasts significantly longer up to 9.400 rpm. The control angles of 124 ° to 182 ° seem to be clearly pleasant to the Polini Box.


Test bench diagram as PDF:  VGL_M244_1_2_POLINI

Test Scooter and Service NEWLINE

The Newline generally shows a different character in terms of power increase at small steering angles than the Elron or the Polini Box.

Similar to the Elron is the rather unimpressed behavior on the changed exhaust control angle. The peak power increases by almost one hp, the maximum torque remains almost identical and the speed range becomes somewhat narrower, as with the Elron, due to the later start of resonance. Even in the second expansion stage, the Newline retains the top position when it comes to torque with 36,7 Nm at 6.137 rpm.


Test bench diagram as PDF:  M244_1_2_NEWLINE

Test Posch Nessie

The Nessie, like the Newline, is intended for moderate control angles, and also shows the clear shift at the start of resonance. Viewed in absolute terms, the Nessie “only” adds 2,5 HP to the top, but in the range between 6.300 rpm and 9.000 rpm it can be clearly seen that the larger outlet angle significantly increases the performance over this range.

Test bench diagram as PDF: M244_1_2_NESSIE

Test Posch Racing Resi

The Racing Resi with its imposing, bulbous appearance already gives the impression of performance and the greed for steering angles. Therefore, the slightly increased outlet angle is not enough to achieve absolute top performance. Here, too, the start of the response is much later. At its peak, the Resi increases by 1,7 HP and this can use the slightly increased exhaust control angle between 7.300 rpm and 10.000 rpm to increase power and torque.


Test bench diagram as PDF: M244_1_2_RAC_RESI

Kingwelle Lakers test

The robust racing exhaust from Lake Constance has already shown on the plugged-in version of the M244 that it is also a good all-rounder. As with all other tested resonance systems, the speed range also shifts in the direction of higher speed, but without the bandwidth being affected. With a band of almost 4.300 rpm, it provides the largest bandwidth in this expansion stage. With 37,8 PS at its peak, the Lakers, at least in this expansion stage, has to admit defeat to the Resi with 37,9 PS - but we are only just warming up on the subject of the steering angle.

The results of the test bench runs, expansion stage 1_2

Here again the results in tabular form. The best values ​​are highlighted in green for each construction stage

Part 4 is already in progress ...


Quattrini M244 Kingwelle - the super tourer

Quattrini M244 king shaft - the super tourer in the first expansion stage "Plug & Play" M244_1

This is part 2 of this Quattrini M244 - Series. In this first construction stage, M244_1, we have the M244 without any further changes, only with spacers on the cylinder head and the cylinder base our engine eingerichtet.

We have entered the resulting control angles in the list for the test plan.

In terms of design, this setup is in the middle of the range of expansion stages.


We have the control angle in the list for the test plan


First we send the all-purpose weapon from Polini into the race.

Polini box exhaust Vespa

Performance diagram Polini exhaust on Quattrin M244i

Test bench diagram POLINI BOX exhaust on Quattrini as PDF: M244_1_POLINI

The result is quite clear. Already at 4000rpm there are 15 HP and 26Nm on the rear wheel.

The maximum values ​​are 30.5PS at 6500rpm and 34.4Nm at 5900rpm.
Even at 9500rpm there are still 22PS on the rear wheel. This constellation already calls for a longer primary translation.



The next test subject comes from FalkR and listen to the name Elron's.

Performance diagram FALRR ELRONi exhaust on Quattrin M244i

Test bench diagram FALKR ELRON exhaust on Quattrini as PDF: M244_1_ELRON

With regard to the maximum values, the Elron ranks as real resonance exhaust already above the Polini Box. But the tide is turning only beyond the 6500rpm in favor of the Elron. In the range before 6500 rpm, the Polini Box has the lead here. After passing the 6500rpm mark, the Elron gains significantly and is above the Polini Box up to the end of revs beyond the 10500rpm.



Another old friend is that JL performance.

JL performance

Performance diagram JL PERFORMANCE exhaust on Quattrin M244i

Test bench diagram JL-PERFORMANCE exhaust on Quattrini as PDF: M244_1_JL_LH

The somewhat outdated concept of the JL still delivers reliable values ​​today. The JL does not cope with the first stage of the engine quite as well as the Elron. With 31PS at 8200rpm, that's something like suffering at a high level. The rather gentle entry and a good performance of 16PS at 4000rpm make the JL a very drivable exhaust with a good start in Reso optics.




The Newline exhaust from Scooter & Service is with us in Scooter Center Shop .


Performance diagram SCOOTER & SERVICE NEWLINE exhaust on Quattrin M244i

Test bench diagram NEWLINE exhaust on Quattrini as PDF: M244_1_NEW_LINE

The new line from Scooters and Service from Hamburg already delivers its maximum power of 6300PS at 32rpm. Even if the playing field doesn't quite fit the Newline, which would like to see a little more steering angle, the manual work from Hamburg delivers a remarkable 6000Nm already at 36rpm. The torque beast in this expansion stage



As the first representative of the "Performance" department, we let Nessie from Posch Performance work on the M244.

Test bench diagram NESSIE - POSCH exhaust on Quattrini as PDF:

Test bench diagram NESSIE - POSCH exhaust on Quattrini as PDF: M244_1_POSCH_NESSIE

Until just before 6500rpm, the world is pretty fine for the Nessie. Then the curve takes a course that suggests that the Nessie would like to see significantly more outlet angles.

Nevertheless, the Nessie with 34.8Nm at approx. 6000 rpm can be counted among the clearly high-torque systems.




Of course we also tested the Racing Resi from Posch Performance.

Test bench diagram RACING RESI- POSCH exhaust on Quattrini as PDF: M244_1_POSCH_RAC_RESI

The Racing Resi from the same manufacturer runs very similar to the Nessie and also requires more ventilation over longer control angles. With almost 35Nm at 6100rpm, the Resi is also well ahead in the league of absolute torque animals.



The Lakers as a thoroughbred racing exhaust, stands well in the feed despite the high performance and engine speeds to be expected with the low control angles.

With almost 36PS at 7700rpm, it is the front runner in terms of performance in this expansion stage.
In the later expansion stages, when higher control angles and a wider outlet come into play, this exhaust can probably live out much better.

Alex builds a Quattrini engine

Vespa Quattrini M244 engine 252ccm - from super tourers to top racers

The story of the Quattrini cylinder

Towards the end of 2015, rumors grew that Max Quatrini launches a potent cylinder for the PX200.

The time has come at the beginning of 2016. The M232 and the big brother M244 are available on the market.

A construction that took some getting used to seemed to follow the concept, a cylinder with a maximum bore of 72mm in the M244 and without a supporting cylinder base.

Due to the design of the crankshaft by Quattrini, with a connecting rod of 126mm, which is rather long for the Vespa engines, the piston does not work so deep in the engine housing and therefore does not need a long, classic cylinder base.

Today, in 2021, the cylinder is enjoying increasing popularity due to its very high torque values ​​and the smooth-running design thanks to the long connecting rod of the Quattrini crankshaft.

Reason enough for us to build an engine with it and play through many possible scenarios for you and see what comes out of it. We have tested exhaust systems and carburettors for you in various stages of expansion.

In the delivery note attached here for our technology department, you will find all the components that we have used for this engine and that, in our opinion, function permanently with this concept.

200 test runs on our test bench

In total, we have over 200 test runs with the Quattrini M244 Completed on our P4 test bench with various engine expansion stages. We have more than 50km measured runs documented and almost 20 liters of fuel burned.
We would like to share the experiences gained from this test with you in this blog series.


Quattrini Vespa Motor - All Parts


To select the parts:

The expected high torques of the M244 speak in any case for a reinforced motor housing.

The experience from many kilometers on the road with our own scooters has taught us that engines in the range from 22 to 25 HP can be implemented as "durable" in conjunction with a Piaggio engine housing.

Our M244 Quattrini cylinder but should be expanded a bit in the course of the test. This is why the choice here is a motor housing from Malossi with membrane inlet.

A pair of Displacement of over 220ccm at erhigher engine speed, can no longer be supplied with sufficient fresh gas via a classic rotary valve on the narrow Vespa crankshaft. That's why we choose this Malossi motor housing with membrane control .

To make the fuel mixture we have one Polini 30mm carburetor used. In this experiment he stands for one Carburettor with 30mm bore. In the course of the tests, we also tried a PHBH30 in a counter-test. We will present the result of this in the following part of this blog series.

On the topic crankshaft we trust king wave. Here we find exactly what we are looking for to build a high-torque, smooth-running and durable engine.

The choice falls on one king wave with 62mm stroke and 128mm connecting rod. Due to the 2mm longer connecting rod and increased stroke, we have the opportunity to work with the control angles by moving the cylinder using spacers on the cylinder head and the cylinder base in the stroke direction. The longer connecting rod in connection with the weighty crankshaft also brings a significant plus in smoothness.

The stroke of 62mm results Cubic capacity 252,4ccm - already very promising to build a torque-oriented engine.

The ignition should keep our tourer running smoothly, so we chose the one here bgm ignition with the PX pole wheel with a mass of 2300g.

The performance of the 252ccm unit is controlled by a bgm superstrong Clutch, the bgm primary 25-62 and one bgm Transmission with the graduation 12-13-17-20 passed on to the rear wheel. The short, fourth gear on the auxiliary shaft keeps the most frequently used gear more stable. With one tooth less in fourth gear, the teeth become significantly wider in the tooth base and thus offer a significantly higher load capacity than the variant with a gear wheel with one more tooth.


Concept and test plan

The requirement for the test setup is that we work from a rather good-natured touring design to a sporty design. Just to be able to depict a section through the possible variants. As a starting point for the test series, we set a basis with small control angles in order to be able to test as many sensible variants as possible later

To determine a starting point, the crankshaft is mounted with bearing dummies and the cylinder is attached to determine the control angle.

Based on this initial data, we can consider to what extent we can sensibly set up the cylinder with spacers and work on the outlet in later stages of expansion.

After measuring back and forth a bit, we decide to start from the middle position of the control angle with one Transfer angle of 124 ° and a Outlet angle of 177 °.




Assembling the engine

Dream team: Malossi | bgm PRO | Kingwelle | Quattrini

The factory new Malossi motor housing will be finished by king wave for the crankshaft with 62mm stroke and the enlarged diameter of the crank webs with 99,4mm. The bearing seat for the bearing on the alternator side is also checked and reworked in individual cases, as the bearing seat is manufactured by Malossi with a very tight tolerance.

We also offer the completely machined housing with a high-quality crankshaft from Kingwelle as a set. We use the set for this engine KWM46228.

The one attached by Malossi Bearing Kingwelle does not recommend 6205 for the alternator side. We follow Kingwelle's recommendation and use a here NU205.

Before inserting the bearings, we process the motor housing and adapt the cylinder and the overcurrent ducts to each other. On a Piaggio engine case, this tends to degenerate into an evening event. The Malossi housing is already designed for the channels of the Malossi Sport and MHR cylinders and requires little rework for the Quattrini M244. Most of the work goes into removing the sealing surface on the cylinder base, which allows the M244 to be used on Piaggio engine housings.

Adjusting the transfer channels to the motor housing is done quite easily. The cylinder base seal shows how little needs to be adjusted here.

All bearings are traditionally used by shrinking in order to avoid damage to the bearing seats by simply pulling in the bearings. The shrinking or cold / warm process offers the advantage that no mechanical stress acts on the surface of the bearing seats and the seat is not widened as a result.


Wandering Malossi engine cases

Another peculiarity of the Malossi motor housing is that the supplied original silent rubbers are too narrow for the motor housing. Or rather, here Malossi has simply oriented the seats for the silent rubbers deeper in the housing than was originally the case. This allows the motor housing to move over the silent rubbers in the direction of the frame.

We have been here with one quite a while ago Spacer set BGM7952SP A remedy was created for the silent rubbers and thus ensured a secure fit of the silent rubbers in the correct position.

The gear

The M244 with a 62mm stroke of the king shaft brought to 252ccm, will transfer a lot of torque to the rear wheel. A guarantee to achieve a high cruising speed at a reduced speed. That enables the primary. Starting from a massive and early onset of torque mountain, the primary can be selected to be long or even very long. With 25 to 62 teeth, we use the longest primary offered by bgm. The reinforced primary repair kit from bgm creates a durable primary drive.

Shift pins and crossbar are included threadlocking assembled.

The bgm secondary gear is set with the smallest possible clearance with the bgm shoulder rings.

Assemble the Malossi motor housing

Further adjustments to the motor housing are no longer necessary and all other innards find their way into their place.

To assemble the crankshaft, the shaft sealing ring is moistened with a little oil so that the sealing lips slide cleanly onto the crankshaft and are not damaged.

The Malossi engine case, contrary to the Piaggio engine case, is without a solid seal composed. Instead of the paper seal, as in a modern engine concept, the housing is Surface seal sealed.

To connect the housing halves, Malossi uses M8 hexagon socket screws. Due to the different lengths of the screws used, a look at the Application listto find the correct attachment point.



bgm PRO Superstrong clutch & King shaft

The King Shaft is supplied with its own thrust washer and special key. The thrust washer has a clear radius that fits exactly to the radius of the crankshaft. A breaking thrust washer is almost impossible.



The Kingwelle has a special feather key on the drive side, which is specially manufactured for Kingwelle and fits exactly into the groove of the coupling hub.

We use one as a coupling bgm Superstrong CR a. With the standard equipment, 10 bgm springs XL, the CR clutch manages a reliable transmission of power up to 40hp. The king shaft coupling nut has a fine thread of the dimension M12x1. The nut comes with screw lock and a Tightening torque of 70Nm attached.


Assembly of further components

The engine is then completed with the rest of the components.
Intake manifold with the Malossi 2-valve membrane. Clutch cover, switch latch, cover for the starter motor and the bgm ignition system with static ignition timing.

Stress-free assembly of the ignition base plate on Malossi engine housings

The Malossi motor housing is reinforced in many places. This can lead to contact between the base plate and the bearing seat when the ignition is installed. The base plate of the ignition must sit tension-free in the centering, so in individual cases the base plate and / or the motor housing must be slightly reworked to ensure a tension-free fit of the base plate.


Check crush dimension

Before the final assembly of the cylinder, we check the pinch size using solder.
Due to the increased stroke, we aim for the squeeze dimension in the range from 1.3mm to 1.4mm and set this using the enclosed cylinder base seals.

By compensating for the larger stroke, there is no need for centering on the cylinder head. For this reason, holes for fitting sleeves are made in the cylinder head and cylinder. The adapter sleeves prevent the spacers used for the cylinder head in the course of the test from protruding into the combustion chamber and causing unwanted damage there.


The new Quattrini engine on the test bench

For the test runs, we set the ignition to 19 ° BTDC.

The runs of the first expansion stage We will introduce M244_1 to you in the next blog post before…

Just a quick note - none of the runs were below the 30PS Mark on the unprocessed M244

Vespa GTS conversion, tuning -> Vespa GTS custom scooter 

Before we get to the Vespa GTS conversions come, first a little review:

The Wasp has been a collector's item since the 50s, which the owner has always liked to individualize. To convert the Vespa, accessories and add-on parts such as mirrors, crash bars, speedometers, badges, anti-theft devices, decorative strips, heated handles, child seats, pillion seats, fuel displays and chrome accessories from manufacturers such as Ardor, Appel, Ulma and Vigano were installed.

Wasp Wideframe Accessories

In the 80's

In England germinates with Mods and scooter boys a movement that soon spills over the canal to Germany and the rest of Europe and will cast its spell over it.
Vespa / Piaggio itself now offers a range of accessories.

There's no arguing about taste! Some people went overboard in the wild 80s and screwed everything on their Vespa that the aftermarket had to offer.

Vespa PX with accessories

The 90s and 2000s

That is the birth of the Scooter Centers: 1992. The Scooter scene is at its zenith in Germany and Europe. Thousands meet on the weekend Scooter meeting = scooter runs, such as the SCOOTERDIVE and many other events to celebrate the vehicles, the music, yourself and your lifestyle.

Find it "Custom shows”Instead, in the off-season these are independent events with a previous and / or subsequent party = nighter. The elaborately converted scooters will be exhibited at the Scooter Customshow and assessed by a jury. The biggest custom shows were, for example, in Hamburg, Munich or the Extravaganza in the Ruhr area and, of course, since 2008 ours too Scootershow in Cologne.

Today: 2020 Modern Vespa models

To date, not much has changed: The modern Vespa is more powerful and engine tuning may become a bit more complex due to the introduction of digital engine control, but the urge for individualization and optimization of the Vespa is unbroken. Not without reason: Vespa has regularly topped the motorbike sales list for years, so of course you want to stand out from the crowd! And the chassis of the Vespa GTS, for example, has significant potential for optimization. Not for nothing, our bgm PRO shock absorbers are for them GTS test winner and bestsellers. LED indicators and LED headlights for GTS & Co are also often converted.

In our Vespa shop we offer you with our own brands bgm and MOTO NOSTRA and selected accessories and tuning suppliers (such as Piaggio, bgm, Moto Nostra, Malossi, Polini, Remus, Scorpion, Akrapovic, Leo Vince, HD Corse, Power 1, a wide range of tuning and accessories for your modern Vespa GTS, Primavera or Sprint .

Do you already know our specials catalogs?


Then as now, there are of course stages of customization. You can do a lot yourself, but if you are talking about an extreme custom project, you are well advised to turn to a professional. As for example with our partner Cafe Racer 69 from Berlin:

Cafe Racer 69

Vespa GTS 300 HPE Custom


The Cafe Racer 69 in Berlin do you get one professional customization of your Vespa. As already said, even with the current Vespa models, be it 125 or 300, Vespa GTS or Vespa Primavera & Vespa Sprint, there is still a lot of room for optimization in the series state. Also because the creative Berlin team of us with, for example bgm & Moto Nostra is supplied, you can assume that only the highest quality parts will be installed!

  • Engine power,
  • Drive,
  • Suspension
  • Brakes,

  • etc.

The Berliners also offer queens Optic tuning Your Vespa on. The purely visual changes can, for example

  • Powder coated
  • Attachments,
  • Moldings,
  • Fittings,
  • benches
  • etc.

Vespa GTS tuning with TÜV 

Our bgm PRO Shock absorber for Vespa GTS are of course TÜV approved. For changes to the chassis, brakes and rims, adjustments to the axle mounts are sometimes necessary. This adjustment for a roadworthy seat without track offset and adjustment of ABS & ASR generally require a technical approval by an expert (DEKRA, TÜV) and can be done at Cafe Racer 69 .

All you need - warehouse

Hello, my name is Maryzabel!

I am a trainee at Scooter Center. I come from Colombia and take you on my big and small adventures in the blog, take a look behind the scenes with you Scooter Center and take you to scooter meetings.

2. My first week

In my first week as a trainee, I got to know the details of the process from ordering to goods registration in the respective departments. Scooter Center not only markets its own brands like: BGM and Moto Nostra, but also more than 300 brands such as: Malossi, Polini, Pinasco, Piaggio and other major brands and manufacturers of scooter parts.

My tasks were to reorder products with modern IT systems depending on the inventory and demand. The receipt of goods, the addition of new products to the system and also the packaging and storage. With so many different parts I've had to deal with, how can so many parts fit on our little scooter?

From the base like Cylinder and carburettor from bearings, seals to all body parts such as entire frame sets or side panels and fenders, all the smallest screws, washers, nuts, split pins up to the accessories, original, restoration, tuning, customizing. Madness what it's all im Scooter Center Warehouse and in Scootershop gives.

Sooner or later, we scooter drivers come into contact with the parts on our scooter. Either planned and “just” for fun: Customizing or tuning, but if it goes stupid with a breakdown, in the middle of the country road. Good to know that you are with the Scooter Center have a partner who can help you quickly and cheaply with the necessary parts and service.


What I know is that so many parts are enough to fill meters, square meters and cubic meters of this huge warehouse over 3 floors and to fill the online shop with tons of data via a modern IT system.

What I also know for sure is that I can build a great Vespa from scratch with the parts from the Scooter Center Be able to build camps. I could build my dream scooter without worry, because in addition to the parts, operating instructions and all the necessary tools are available directly from stock.

I can assure you and have seen it myself. The Scooter slogan applies perfectly: ALL YOU NEED

The MALOSSI Multivar variator Thanks to a significantly optimized shifting process, it already produces very good results on series engines in terms of improving top speed and acceleration, and that without putting any more stress on the engine.

The roller races have been specifically calculated for each model and the useful scope of the sliding surface of the belt has also been expanded.

With such a high level of technological effort, it is almost natural that the best materials and the most modern production methods are used:

  • Self-lubricating sliding bush made of sintered steel
  • Alloy steel hub
  • Sliding surface with a layer of hard, polished and lapped chrome
  • Half pulley made of silicon-aluminum alloy with precision NC machines
  • Diamond finishing

Nothing stands in the way of completely new driving fun. Jerk-free starting, greater shifting comfort, mechanical silence even at high speeds and constant driving performance are the result.


· MALOSSI also offers an air filter insert for the original air filter box

Reinforced Malossi engine housing for Vespa PX 200

Malossi offers two new reinforced PX200 motor housings, V-One and VR-One.

Both housing types are already designed for use with a Malossi 210ccm Sport or 210 / 221ccm MHR cylinder. The motor housing is already manufactured to match in the area of ​​the overcurrent ducts, no more adjustments need to be made. Of course, all other cylinders can also be used on these housings.

Biggest novelty of Malossi motor housing is the No loose motor bolts as well as the center seal made of sealing paper. The housing is now assembled with M8 Allen screws Sealing takes place with a temperature-stable sealing compound (TIP: anaerobic curing sealant from Loctite Loctide 574 ).

The housings have at all critical points Reinforcements (Auxiliary shaft, crankcase with five screws, swing arm and shock absorber mount). More material was planned for the sealing surfaces, so tuners can let off steam here to their hearts' content. The crankshaft bearing on the alternator side is now significantly larger and more stable (25x52x15mm instead of 25x38x15).

Silent rubbers on the engine and shock absorber mounts are included in the scope of delivery of both types.

So the GTS has real pressure from below, that There is an increase in performance across the entire engine speed range on, and thanks to the Malossi Forcemaster2, the rev limiter is reduced by 1.000 rpm. raised, measured on this vehicle 10.500 rpm.

As already reported by us here, the comes from Piaggio Electric Vespa.

Vespa models - new colors, less power and a lot of lifestyle

We had changes to the engine (Euro 4) in the exhibition news of Intermot in Cologne already discussed. In Milan, Piaggio is showing new colors and a lot of lifestyle.

A special model of the Vespa GTS 300 Super in green metallic with aluminum applications in CNC style, e.g. cascade, fender nipples. Interesting cascade with an even more interesting horn section - opinions will differ on this ;-)

More deets: Bitubo shock absorber in front, only for the trade fair or series? In any case, the adjustable levers are standard! CNC footrests, mirrors in CNC design, new oil control screw and vario cover.


Personally, I like the Vespa Seigiorni very much. Piaggio thus ties in with the early 50s, because sports models of the Vespa have been produced parallel to the series vehicles since 1947. The Vespa Sport, known as the “Sei Giorni” after the model that had great success in the 1951 international regularity race of the same name. An original Vespa Sei Giorni is incredibly valuable.


DellOrto has been the standard supplier for the Italian motorcycle and scooter industry since 1933. Dell'Orto was the largest supplier of two-wheeled carburetors in Europe from the 1960s to the 1980s; today the company works closely with Bosch and Mikuni. At the Scooter Center of course you get all available DellOrto carburetors and DellOrto spare parts such as nozzles, carburetor needles and slides quickly and cheaply.


The Scomadi with 300cc was never realized. Rumors say Piaggio has refused to supply 300cc engines to a competitor product. Today a prototype with me 400ccm. At the moment everyone at Scomadi is very busy, we will try to find out later which engine is being installed.
