High-Torque lightweight 3-shoe flywheel helps to increase acceleration and improves throttle feeling. Made from tough Swiss 7075 T6 alu and hard coated for extra durability. Strategically lightened compared to the standard #358532 flywheel, reducing rotating weight without sacrificing strength or durability. Highly-polished, smooth flyweight pins are factory-pressed. Knurled outer edge for easy starting on starter box. Integrated cover prevents dirt from entering the engine bearing.
