CRF450X Boyeson Clutch cover, used but in immaculate condition. Came off of my 05 450X, should fit from 05-17, but make sure before you order. This one appears to be the magnesium version, as opposed to the black version. The gasket is stuck to the cover, but is not dried out and should be good to put on directly. I just wanted to go back to an OEM cover to match the styling on my bike.
