Fast Arrow CNC rear pulley/ torque drive for Piaggio/ Gilera 125/180cc 2-stroke maxi-scooters.

The first complete solution for the rear pulley of Runner & Typhoon maxi-scooters. The aluminium pulley faces are CNC machined to precise angles and ribbed to increase the surface area. This combination of material and construction has many benefits over the original. The reduced rotating mass, precisely optimised angles & reduced variator temperatures, result in extra power at the back wheel. Perfect for tuned engines.

A Vespa GTS 300cc drive belt is required with this pulley.
