Clutch bell -POLINI Evolution- Piaggio 400-500cc Master

Polini produces clutch bells with a reduced weight in order to minimize the moment of inertia. This improves the acceleration without having to accept other disadvantages. Made of high resistance and precision machined steel, the cooling fins and the additional milled holes help to keep the clutch temperature low. This is especially important in city traffic, where the clutch is exposed to immense loads in stop and go traffic.

A clutch that is too hot tends to wear prematurely, to have a too low engagement speed and to slip.

The high-quality material and the stiffening via the cooling fin structure enable precise concentricity, important for a cleanly engaging clutch without jerking.
