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.

Please note: On some models you need to remove the shim washer; the washer at the front with the retaining circlip needs to be removed to allow the clutch bell to fit. It may also be the case that, on some models, the spacer at the rear of the pulley needs to be changed or shimmed out.
