Description

The BGM Pro Evolution clutch bell has a ring-shaped fine-ribbed reinforcement ring. This ensures excellent heat dissipation. This results in very good starting behavior and best acceleration from low speeds.

This technological innovation is a result of extensive testing.

The design of the clutch bell is based on the following principles:

The design of the cooling fins allows for a larger surface area to dissipate heat, thereby significantly reducing the operating temperature of the clutch bell. Durability is greatly increased.

The stresses of city driving, hill climbs and pillion riding place special demands on a clutch system.

In high-performance racing engines, the clutch system is also subject to extreme speed loads. The centrifugal forces increase as the square of the engine speed. The reinforced cooling fin ring counteracts this load and protects the bell against failure.
