INTAKE FITTING

The Polini kit contains the complete intake tract, consisting of:

large membrane inlet, intake manifold and connecting rubber. The 6-flap membrane is equipped with 0.4mm thick plate material. The intake manifold is intended for use with a Ø34mm carburetor cross section (carburetor connection width of the rubber is Ø44-45mm). Modifications in the area of the frame cutout for the carburetor may be necessary.

PISTON

The Polini tuning set for Vespa relies on the well-known Asso piston of the Polini Aprilia AF1 kits, like the ones from FALC Racing is used in its 153cc cylinder (we can offer the very high-quality Ø60mm Wössner piston from Overrev very much).

CRANKSHAFT

Any shaft with a stroke of 54mm and a connecting rod length of 105mm can be used as the crankshaft.
The connecting rod length not only benefits the better connecting rod ratio, but also reduces the necessary housing adjustments for the overcurrent channels to a minimum.

SPINDLES

The motor housing must be spindled with a 54mm stroke for the required crankshaft.

CYLINDER HEAD

In addition to the conventional screw connection, the cylinder head is screwed onto the continuous (longer, enclosed) cylinder stud bolts with 4 screws.

Recommended accessories / setup:

Crankshaft: P2100070 or comparable (54 / 105mm)
Exhaust system: P2000416 or similar
Ignition: P1710554 or similar
Dynamic ignition timing (with ignition P1710554): 4,8mm in front of the upper one
Piston dead center at 4500 rpm
Spark plug: NGK BR9EG or comparable

CONCLUSION:

Very interesting alternative for normal engine cases to the often unavailable FALC Racing cylinder. If you are looking for performance in the range well above 25PS, you will find it here!

Egig Performance Vespa Tuning

Smallframe, Vespa

Egig Performance Vespa Tuning Shop

We have many popular Vespa tuning parts in our shop from Egig performance. Here we introduce you to the manufacturer and the highlights in our program.

Erich, aka Egig

Egig, based in the scooter paradise of South Tyrol, was created by Passion for screwing. Egig is driven by the fascination in the combination of the latest 2-stroke technology, packaged in the old tin. Owner Erich, alias Egig, has been screwing things since he was 11 years old (!!) Smallframe Vespa scooters and has perfected this from year to year on its own racing and road scooters and impressively demonstrated it.

The Company Egig performance was created many years later when he noticed that the tuning items available on the market were no longer satisfactory in terms of quality or performance. This has resulted in a fine portfolio High-end Vespa tuning products around the Smallframe. The innovative tuning parts from this Egig product range are continuously perfected, further developed and expanded.

Sport exhaust EGIG PERFORMANCE 'Super Banana Sport' for Vespa Smallframe PV125 / ET3

The EGIG PERFORMANCE SUPERBANANA Exhaust systems are perfect for inconspicuous but powerful SmallframeEngines. They score with high performance, good drivability and a wide speed range.

The Superbanana from EGIG PERFORMACE is a resonance exhaust, based on the look of a conventional banana exhaust, as already used by Piaggio in the popular SS50 / 90 and ET3 models. The Superbanana is designed to provide powerful engines from 125cc with an exhaust that is inconspicuous both visually and acoustically, but acts on the level of a classic resonance exhaust.

Details about the superbanana

SOUND INSULATION

Inside there is a silencer that reduces the volume to the smallest possible level without causing a loss of performance or heat build-up. The difference in noise development compared to an original or other classic 'banana' is only a few more DB and that with + 50% or more performance increase, depending on the engine type.

FEATURES SUPER BANANA SPORTS

For cylinders with a modern layout (e.g. Quattrini, Polini Evo, W-Force, Egig170)
One-piece or multi-piece outlets
Overcurrent angle: 126 ° -128 °
Outlet angle: 185 ° -192 °
Pre-discharge angle: 29-32 °
Elbow Ø32mm
Suitable for luggage compartments
Tires up to 3.50 wide
Stud spacing 54-62mm *
not suitable for Vespa PK (with cutting out of the side plate assembly also possible on PK models)

* If the Superbanana is installed on 54mm, the M8 collar nut with 10mm wrench size enclosed with the exhaust must be used on the inside of the manifold.

The Superbanana exhaust systems are designed as the final expansion stage for fast street engines. You therefore also need the right environment to deliver the appropriate performance. If the engine is still in production (or has been built rather conservatively despite the 133cc cylinder), the exhaust can only intervene to a limited extent. Here we would rather recommend a BGM Touring or BGM Sport Banana, as they can support the engine much better in such an environment.
However, if the conditions are right (cylinder, intake revision, carburetor size, etc.), the Superbanana currently offers the highest performance increase that can be achieved with an inconspicuous exhaust system.

In order to meet different requirements here, there are two different types, the Sport and Touring versions... read more

Clutch -EGIG PERFORMANCE- One Finger Clutch 5-discs - Vespa V50, PK ...

Sports clutch EGIG PERFORMANCE - One Finger Clutch - smooth clutch for Smallframe Motors up to 30HP

In contrast to a 3 or 4-plate clutch, the number of springs can be reduced with the 5-plate clutch. This results in a clutch that is very easy to operate.
In connection with a PK XL2 cover (or alternatively a Crimaz coupling separator) you pull the coupling with one finger. With 6 feathers with the little finger.

Details about the one finger clutch

Also fits in an original primary without a repkit
only for repkits screwed from behind (with repkits screwed from the outside, the screw heads may be on the inner basket)
Oil 400-500ml SAE 30
no spacers necessary
The pads of the Xl2 / HP 4 discs can also be used or Fabbri 4s carbon discs

Exhaust -EGIG PERFORMANCE Mamba Vespa ET3, PV125

Racing exhaust -EGIG PERFORMANCE- Mamba - midrange exhaust for powerful road tuning for Vespa Smallframe

Classic resonance exhaust that produces a very nice performance range with high performance and revving in the appropriate environment of a revised engine.

The Mamba racing exhaust from EGIG PERFORMANCE from South Tyrol is a great midrange system that is located between Python and Cobra.

Details about the mamba

The very well processed resonance exhaust system is designed for engines between 100-144ccm.
It works very well on powerful cylinders such as the Quattrini M1L60 or Polini Evo. The exhaust rewards the right control angle of the cylinder with a broad power plateau and a rich torque. Power consumption from approx. 6000 rpm, power peak around 8000 rpm which, however, is kept above 1500 rpm.

Exhaust material: steel, unpainted (painting or galvanic treatment recommended for rust protection
Silencer: aluminum, Ø70mm
Distance between stud bolts outlet: 54-60mm
Elbow diameter: Ø32mm
comparable to e.g. L&S Franz, LTH Midrange, VSP Road

The engine housing has the stable crankshaft needle bearing of the PK ETS models. This means that the ultra-stable “ETS” type crankshaft can be used. This has a crankshaft stub diameter of a whopping Ø25mm.
If the housing is to be used with 50-112ccm cylinders, we also offer a corresponding crankshaft with 43mm stroke (125cc = 51mm stroke).

The intake manifold has the modern 3-hole mounting method. Here we offer corresponding intake manifolds with 3-hole attachment and at the same time the correct manifold course for the V50 / PV / ET3 frames.

Components that differ from a conventional one Smallframemotor with two shift cables (V50, PV, ET3):

XL2 shift fork
Crankshaft with Ø25mm alternator-side crankshaft stub, type "ETS"
Intake manifold with 3-hole attachment

SERVICES

The SE125 enclosures have a long rotary valve sealing surface (42mm). As a result, the inlet can be enlarged very much, making them ideal for high-performance tuning based on rotary valves.

CYLINDER

The cylinder base bore is 61,5mm, therefore suitable for all standard and common tuning cylinders (not Falc, Quattrini SP09 etc.). So it doesn't have to be spindled.

DELIVERY

The housing is delivered without bearings, without nuts, without cylinder studs but with all silent blocks / silent rubbers. In addition, the shift cable adapter for two shift cables is already assembled.

Spring for primary -BGM PRO- Vespa Smallframe V50, Primavera, PK

News, Smallframe, Vespa

Vespa Smallframe with more power

Around SmallframeThe potential of engines has increased significantly in recent years and appears to be growing steadily.

Power and torque values of clearly over 35PS / 30Nm are found more and more frequently. As a result, other components are of course also stressed significantly more.

Primary springs need to be stronger

An important and highly stressed link between the crankshaft and the transmission is that Clutch and the primary drive. ThatThe weakest link in this chain are the feathers the shock absorption.

Reinforced bgm PRO springs for Vespa Smallframe Primarily buy here

All of the torque is transferred to the rear wheel through them. They ensure uniform power transmission to the gearbox and dampen the uneven running of the crank mechanism between the dead centers. Heavy crankshafts, centrifugal masses that are becoming lighter and lighter and heavy load changes not only in racing, shorten the difficult life of the original springs.

New reinforced springs from bgm PRO

Suitable for the BGM PRO primary repair kits BGM0190, BGM0192, MMW Hartz4/ 5 and of course the original primary repair kits, we have added reinforced springs to our range for you.

More power with the new bgm PRO springs

Compared to a Piaggio spring, the BGM spring offers more spring force and, thanks to the selection of the spring wire, more travel.

Due to the greater possible travel and the increased spring rate, the gearbox and primary drive are protected from tooth breaking load peaks even under harsh operating conditions.

Since you cannot simply increase the dimensions significantly to increase the durability, due to the installation conditions, we have paid attention to good material and workmanship for the spring. Oteva is an extremely resistant spring steel that is used for high dynamic loads and is characterized, among other things, by its durability even under the influence of high temperatures with simultaneous high mechanical stress. To further increase the durability of the spring, the surface is shot-peened.

Primary repair kit and clutch basket bgm Pro Vespa Smallframe

In performance-enhanced people Smallframe In engines, the soft cover plates of the primary shock absorber are a weak point. Under higher loads, the springs tend to press against the plate and after a while the spring finds its way into freedom, i.e. the way into the gearbox - not good.

With the bgm Pro primary repair kit you can prevent this defect. The base plate and clutch basket made in Germany from 42CrMo4 keep even the harder springs in check.

Vespa Smallframe Primary repair kit

The "small primary repair kit" BGM0192 you can use it with the normal clutch basket. The cover plate is suitable for V50 / XL1 and XL2 couplings.

Vespa Smallframe Primary repair kit with clutch basket

The "great primary repair kit" BGM0190 colors additionally with a reinforced clutch basket. The basket and the cover plate are also made of 42CrMo4 and the surfaces are additionally hardened in order to achieve even greater wear resistance.

So that you can easily do the Primary gears on the crankshaft, the clutch basket has a suitable recess at one point.

You can also do one here XL2 coupling use. The clutch basket is adapted accordingly.

You can use both primary repair kits with the normal standard or reinforced springs.

The Feathers RED we recommend for engines up to approx. 25HP. If your unit should produce significantly more power or if the engine is to be used in racing, then you can also use the hard, YELLOW feathers fall back on.

If you want to use the reinforced springs, you will have to modify the large primary gear slightly. The pocket in which the spring works must be expanded to 12,5mm.

New Vespa clutch for Smallframe

After the success of the BGM Superstrong Vespa clutch for the Vespa Largeframes, we also have a solution for the Vespa Smallframes developed. Now in Scooter Center Vespa shop available

As with the Vespa clutch for the large engines, the Components made in Germany.

Brief overview:

Made in Germany
higher transmission power due to more surface
longer service life due to more material
Even contact pressure thanks to 16 bgm PRO XL clutch springs
perfect coordination option
Mobile with Vespa PK XL1 and PK XL2 cover
stable coupling hub with internal thread for standard pullers
extremely resilient, also for engines with 30HP +
Plug & Play coupling is delivered ready for installation
Spacer available

Superstrong - Extremely high performance

The clutch hub as well as the cover and thrust washer are made 42CrMo4 manufactured. The force is from bgm Racing red clutch plates transfer. The design of the clutch linings in the Vespa PK-XL / Vespa V50 version offers more space to transmit the torque. In this context, more material naturally also means a longer service life.

16 springs for even contact pressure

When it comes to springs, we use tried and tested methods. sixteen bgm Pro XL springs ensure even contact pressure.

Due to the number of springs and the arrangement on the largest possible extent, a very even pressure behavior is achieved. This effectively prevents the two pressure disks from tilting or locking.

Thanks to the perfect coordination of spring stiffness and number, paired with the stiff design of the pressure plates, the clutch can be operated easily even with a PK-XL1 clutch cover.
The contact pressure of the bgm Pro XL springs and the coefficient of friction of the Racing red pads have a Test in our X-Mas duel already withstood the 30PS.

Highly stable & well thought-out coupling hub

The clutch hub is designed for a primary with a shock absorber and has an M28x1 internal thread for pulling off. (The extractors of the Vespa fan wheels with electronic ignition fit there.) Thanks to the internal thread, the area around the cone could be made much more massive. The more stable design without the senseless weakening by an unnecessary keyway makes the hub the first choice for every load. We recommend our for assembly Coupling nut and threadlocking. To dismantle the clutch or to change the linings in the engine, our bgm multitool BGM8819 should be used.

Plug & Play Ready-to-install delivery

We offer you the bgm Superstrong for the Vespa clutch for Smallframe Fully assembled with 4-disc bgm Racing red clutch linings and 1 mm steel discs.

For PK XL1 & XL2 clutch cover

The pressure plate is for holding a PK-XL2 pressure plate designed and can therefore be used on a PK-XL1 or on a PK-XL2 clutch cover.

Optional spacers available

Depending on the combination of engine housing, auxiliary shaft and clutch cover, it may be necessary to place the clutch cover underneath. For this we offer you a matching spacer set.
