Tusk Clutch Cover Gaskets are made from quality materials to meet or exceed OEM requirements. These gaskets are made to replace the stock clutch cover gaskets with the same fitment and sealing properties but at a better price. Some clutch cover gaskets are a synthetic fiber type gasket while others are a rubber O-ring style. The Tusk gasket will match your machine's requirements (same as stock). Replacing the clutch cover gasket is a must whenever the cover is removed to ensure proper sealing. Also Fits: Honda CRF450X 2005-2009 Honda CRF450X 2012-2017
