  • Tusk Clutch Spring Set

    Tusk Clutch Spring Set

    Daniel in OK

    Needed new price point can’t be beat

    These were to freshen up a clutch and they do their job and seem to be holding up. There hasn’t been any slip that I can tell so they hold up well to a modded CR250

    Tusk Competition Clutch Kit

    Daniel in OK

    Great part

    I abuse clutches in the woods on a mx bike that I won’t gear down because I don’t want to give up any top speed since I ride woods 30% of the time and the rest is open fields or dunes. I change with fresh fluid every ride and these are holding up

    Takes a beating

    It’s a clutch and I keep my fluids changed every ride. I am hard on clutches doing a lot of trail and enduro.

    Wiseco Piston Kit

    jason in IN

    I have bought hundreds of wiesco kits in the past, ...

    First one arrived without a wrist pin, so I called Rocky Mountain customer service. They got shots of wiesco immediately and sent me a whole other kit, wrist pin included this time. Got it the next day.
