Clutch bgm PRO Superstrong CR for Vespa

NEW: clutch bgm PRO Superstrong “CR” for Vespa

Our 1000 times proven bgm PRO Superstrong clutch for the Vespa Largeframe-Engines received an update.
In the version "Superstrong CR”The CR clutch facings can be assembled without machining.

Pre-assembled coupling available

Only the upper surface is specially processed and offers space for the reinforcement of the cover plate.
Nothing changes in the mere assembly of the coupling itself.

Easy construction

As a rule, as with the Cosa version of the Superstrong, it is sufficient to machine the clutch cover.
The necessary Information about this you can find in Article download area in our shop.

The clutch basket of the CR version has not increased in outer diameter.

We only changed the contour so that the CR pads fit without machining.

All other components such as the hub, pinion and steel disks are identical to those the Superstrong Cosa version.

New Vespa clutches:

The Superstrong CR is available in the following versions:

Plug & Play

Vespa PX80/PX125/PX150/Cosa125/Cosa200 (the large primary gear has 67 or 68 teeth)

Vespa PX200 (the large primary gear has 65 teeth or the BGM primary gear has 64 teeth)

Kit

Alternatively, you can of course also put together your own CR coupling.

Recommendation for torque monsters

For high-torque motors, we recommend that you change the Primary gear to 64 teeth also a reinforced repair kit. The stronger springs offer better shock absorption and mechanically digest the higher torque of the Monster motors better than their series counterparts.

Advantages of the CR rubbers

We have the advantages of CR pads on powerful engines in Contribution of the covering sets already mentioned. Here is an excerpt from it again:

"Why can such a small, flat clutch lining work better than the larger cork lining?"
In addition to the lining material with a better coefficient of friction, the keywords here are “effective radius”.
The decisive factor is the outer diameter in connection with the height of the covering and the resulting radius.

This means that the lever arm facing the torque acting on the hub is longer with the same outer diameter because the center of the lining is further away from the pivot point of the shaft. In the end, the simple law of leverage. It is therefore “easier” for the clutch lining to cope with the torque introduced. So he literally sits on the longer lever.

On the one hand, it is the common, ubiquitous physics and, on the other hand, the type of lining material that enables a clutch with CR linings to transmit a higher torque with the same pressure of the springs.

A CR pad set enables a clean and freely separating clutch with very little lever travel. The lining material also enables very simple and safe switching operations at high speeds.
