Polini Racing Clutch Bell – Piaggio Ciao / SI / Bravo / Grillo – empty

Detailed product description: Get the maximum out of your centrifugal clutch! The Polini Racing Clutch Bell is the ultimate upgrade for all tuned Piaggio mopeds with standard belt drive (without variomatic). Unlike the original bell, this version is specifically designed for high RPMs and thermal stress.

The special feature of the Polini bell is its extremely robust construction and improved heat dissipation. In high-performance engines, a lot of friction heat is generated when engaging at higher RPMs – the Polini bell does not warp and ensures a consistently clean power transfer without the clutch "wandering". Since the bell is delivered empty, you have the complete freedom to equip it with your preferred clutch shoes and springs.

Installation and information tips:

• Advantage: Due to the higher material quality, this bell offers significantly better safety with high-revving engines (prevention of bell breakage).

• Installation: The bell is simply swapped for the original part. Make sure that the spacer behind the clutch is seated correctly so that the bell can rotate freely.

• Combination: We recommend using reinforced clutch springs to fully exploit the potential of this racing clutch bell and to raise the engagement point.
