Full circle crankshafts increase crank case compression and low end power. The 360 degree webs generate greater stability and longer life over cut back cranks.
NOTE: 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 to make sure that your scooter accepts this part.
We recommend upgrading your crankshaft when installing performance cylinder kits.
