clutch bell Polini Speed Bell Evolution 2 107mm for Minarelli

Polini EVO II Speed Bell is lighter and more revvy than the previous model. The single-piece clutch bell is CNC-machined from a single block, unlike the Malossi Wing bell. Additional ventilation holes have been machined from the bell, giving it a more aggressive look and extra cooling capabilities. Great clutch bell for high-end use but of course can be used for stock or lightly tuned engines.

diameter: 107mm (In combination with a 107mm clutch this clutch bell can also be used on scooters with the older 105mm clutch system.)
weight: 425g
