The Polini Maxi-Speed 125mm Clutch Bell is an aftermarket performance clutch bell designed for scooters equipped with GY6 125cc to 150cc engines (e.g., Honda Ruckus GY6, Kymco, SYM, PGO). It directly replaces the original clutch bell in the CVT transmission.
The clutch bell is the mechanical component that receives the centrifugal forces from the friction weights or discs as engine speed increases, thus transmitting torque to the CVT belt and then to the rear wheel. The Polini Maxi-Speed version is optimized for:
an improved friction surface profile,
enhanced heat management,
reduced slippage at mid and high RPMs,
a crisper and more consistent torque response across the entire engine range.
The precisely machined 125mm diameter matches the standard of many high-performance clutch kits on GY6 platforms, ensuring compatibility and reliable mechanical integration.
