New bgm Superstrong clutch Vespa Largeframe & Smallframe

,

The Superstrong coupling family receives in the large and Smallframe Growth.

For the Largeframe We equip the tried and tested models Superstrong with a 24 tooth DRT pinion off to the translation on an original 65 teeth primary gear to extend.

Especially with the current cylinders from Malossi and Poliniwhich provide a very high torque, it makes sense to lengthen the translation to convert the potential into speed.

Im Smallframe Sector an additional coupling spider is suitably deposited for DRT auxiliary shafts in the Superstrong clutches offered. DRT auxiliary waves are a useful addition to almost all engine concepts in the SF area in order to adapt the transmission to a more sporty driving style. There are one here Variety of gradation variants to disposal. The auxiliary shafts offered by DRT are about 1,5mm higher.

Here the DRT variant:

The bgm PRO Superstrong Cosa coupling is the plug n play solution - Made in Germany.

This quality Vespa clutch is with 20,21,22, 23, XNUMX and XNUMX teeth available: Vespa clutch

You get a ready-to-install Vespa Cosa clutch with the supplied reinforced clutch springs in a performance range of 20HP / 22Nm works fine.
With separately available springs with a higher spring rate *, the clutch can keep up with setups without complaint significantly above 30 PS and is still easy to operate.

Features:

  • One-piece CNC milled clutch basket - Made in Germany.
  • The extremely robust construction offers perfect and precise guidance of the hub thanks to the shaft teeth.
  • The hub is made of high-strength steel to prevent the hub from cracking.
  • Thanks to the use of ten springs, there is sufficient spring force even for high-torque setups with little effort on the clutch lever.
  • Clutch basket hardened by nitriding, worn out clutch baskets are a thing of the past.
  • Always precise cutting thanks to the pressed sintered bushing.
  • Every coupling is subjected to a quality control. In this way we guarantee that we will deliver a functioning and ready-to-install coupling.

The scope of delivery includes the complete ready-to-install clutch with bgm PRO Cosa clutch linings and ten reinforced springs. A new O-ring for the clutch cover and the crescent wedge.

 

TECH TIPS:

The number of teeth on the clutch is important for the length of the total reduction. This can also be varied. Possible combinations:

  • Original 20 teeth: 21T, 22T
  • Original 21 teeth: 20T, 21T, 22T
  • Original 22 teeth: 20T, 21T, 22T
  • Original 23 teeth: 21T, 23T

For models up to and including 150cc, a small cast aluminum lug in the motor housing must be removed to mount the clutch. This can be easily snapped off with larger pliers. With some clutch covers, minimal material has to be removed from the drip nose at 12 o'clock in the area of ​​the radius.

The Vespam clutch can be installed in almost all engines of the so-called Vespa Largeframe Class. These are all vehicles whose chassis prefix is ​​three-digit (e.g. VNB, VNL, VNX etc., the addition 1T, 2T, 3T is not taken into account) and which have the carburetor installed directly on the engine housing (not in the frame or on the cylinder). On some old vehicles before the Vespa PX era, the thin washer (1,5mm) under the clutch has to be replaced with that of the PX models (3,3mm Item No. 7671297 http://www.scooter-center.com/product/7671297).

Spring rate N / mm
Original Piaggio 4,0

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.

Vespa clutch bgm Superstrong for Vespa Smallframe

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.
