When it came to a top end piston refresh I wanted piece of mind on all parts. Cometics pricy but the absolute best in quality fit and durability.

Nice OEM Quality, at a Great 1 piece Price. Keeps People Riding Affordably. I recommend this Part especially when having to do Constant Clutch maintenance or Replacement Due to Hard Racing.

It was time for a new top since its been a while, so why not try this piston kit. Only took 20 years to have to rebuilt an old 2 Smoker and it was a piece of cake. This kit worked out awesome.

Very nice cam. Improvement was nice to sons crf250x. Had stock cam fail with rocker. Aftermarket rocker required light grinding as described in directions. Stock rocker assembly would have worked without modification. Thinking about a stage 2 for my 450r.
