Product Overview
High quality item made in Italy by Mazzachelli, this full circle crank fits P125, P150, and late model Sprints, Sprint Veloces, and Supers. Full circle crankshafts increase crank case compression and low end power. The 360 degree webs generate greater stability and longer life.
This crankshaft is for use on reed valve inducted engines only. To install in a rotary inducted engine, the rotary pad must be completely removed and a reed manifold installed. Please check the VIN listing above to make sure that your scooter accepts this part. We recommend upgrading your crankshaft when installing performance cylinder kits. Not legal for use in California on pollution controlled vehicles. Check local laws before installing.
