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.

I love wiseco pistons. They always fit well, they look great (which feel reassuring when doing the top end rebuild). I will always buy wiseco pistons.

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.

Everything about these valves is great. These are the only ones that I use. I combine these with Kibblewhites valve spring/hardware kit. Excellent Quality.
