    Curious if anybody has used these on a 2-stroke GP bike?
    Wheels, cranks, trans.

    I know they are a little more expensive than the OEMs, aside from that how did it go?

    Thanks

    they work great on the diesels... hopefully your 2T bike doesnt have oddball bearing sizes.

    Are you talking Hybrid Ceramics like World Wide Bearings sales? Or full ceramics? I don't know anybody running full ceramics, but I know a few people running ceramic hybrids in both wheels and complete engines, and gearboxes with great results. I want to say the quote I got to do my RZ motor and gear box with hybrid ceramics was $675 , it included 4 crank , 2 trans , 1 water pump Bearing and a single Ceramic Ball for your clutch pusher.

    Thanks all for your replies, good to know people are using them without catastrophic failures! Particularly ones inside the motor.

    To my understanding. A failure inside the motor is pretty unlikely with the hybrid bearings. It has steel races and ceramic balls. This combination is supposedly pretty reliable. And inside a motor shouldn't see any sharp impacts which is what would cause the common failure mode for ceramic.
