Old clutch was super sticky when cold. Killed the engine when put into gear. This new Tusk clutch kit made it like new again. Easy installation. It doesn't come with the cover gasket. I reused mine.

Worked for my Honda CRF450 and no leaks so far. Took a gamble since I usually only go OEM but very happy and much cheaper.

This piston kit was exactly what I was looking for. It fit perfectly during the top-end rebuild and has performed exactly as it should. Ive always trusted Wiseco for pistons because the quality is consistently solid and they hold up great under abuse. Another great experience with this kit.
