ATHENA Clutch Steel Plate Kit for YAMAHA YZ 85 2002-2022

On YAMAHA YZ 85 from 2002 to 2022, the ATHENA P40240059 clutch steel plate kit fits in place of the original part. The steel plates, made of steel or aluminium depending on the model, are the surface the friction plates grip against. Warped or glazed, they stop the clutch from working properly, even with new linings.
