The BGM Carbon clutch facings have a much harder and more wear resistant facing material than the standard BGM facings. This makes them even more temperature stable, but they also need a certain basic temperature to develop sufficient grip.
They also need higher spring rates than the standard clutch facing material to avoid slipping at the same engine torque.

This makes BGM Carbon clutch facings predestined for the race track where they can reach their full potential.
An ideal application are frequent starts under full load, e.g. during acceleration races or continuous load in endurance racing.

The CR single pad has pad material on both sides and is therefore suitable for the following clutch types:

• Lambretta LTH Liedolsheim (7x)
• Vespa Smallframe MMW Hartz4 (4x)
• Vespa Smallframe MMW Hartz5 (5x)

Note: For the Vespa PX Superstrong CR couplings please use the complete pad set (BGM8085SKT) because only here the required cover plate, only one side is used, is included.

A CR clutch facing set enables a clean and free separating clutch even at very low lever travel. Furthermore, the lining material enables very simple and safe shifting operations at high speeds.

RECOMMENDATION
We also recommend a low-alloy gear oil of the classes API GL3/GL4 for high performance engines to avoid slipping of the clutch even under extreme loads. This also applies to our BGM Superstrong/Superstrong CR couplings. The old engine oil specification SAE30 corresponds to the current gear oil specification SAE 85W/90.
