Polini Evolution maxi speed clutch bell for Piaggio/ Vespa 125cc 3-valve A/C 4-stroke maxi-scooters.

The Evo clutch bell runs rings around the competition. CNC machined from a single piece of metal, ensuring a perfectly balanced & solid component. Surface area is significantly increased over the original bell and the large vents reduce the operating temperature, increasing efficiency. Works to its full potential when coupled with a Polini Speed Clutch.

Inner diameter:
125mm
