Wiseco, Clutch Basket, Yamaha YZ450F '04-17

Wiseco forged clutch baskets have greater strength due to "feature aligned grain flow." Compared to castings or products machined from billet, Wiseco Precision Forgings can be lighter and still have increased mechanical properties resulting in higher strength, ductility, and resistance to impact and fatigue. Wiseco's clutch baskets are forged from lightweight, high strength, certified, aerospace grade aluminum alloy. Wiseco's CNC machining process produces each clutch basket dimensionally the same as the next. Weight reducing relief cuts on the outside diameter of the clutch basket reduce rotational mass, which lowers the centrifugal force acting on the clutch basket and increases overall acceleration of the engine. Large oiling holes in the clutch basket tangs increase lubrication, reduce heat build up, and reduce weight. Hard anodized for an ultra tough, abrasive resistant surface ensures a long life of smooth clutch operation through the elimination of wear on the sides of the clutch basket tabs. A Teflon coating seals the clutch basket to create a near frictionless surface for the clutch disks to glide upon. Supplied with high quality fasteners, complete with pre-applied thread locker, for a secure grip during assembly.
