Kolvkit CP-pistons

The first choice for all top level MX pros simply because of the unmatched quality and performance.
Project X pistons was originally developed with Ricky Carmichel and has since then been used by all US Supercross champions after him including James Stewart, Ryan Dungey and Ryan Villopoto.
Only comes as high compression pistons, one step above OEM compression ratio is usually safe if used with a high quality fuel and assuring that enough fuel are supplied. For higher compression ratios knowledge are needed in combination with matching fuel/ignition curves and other engine parts.
Don´t forget to order gaskets with your piston, Cometic gaskets are the ones that are recomended by CP-Carrillo.
Special pistons with higher compression ratios are not in stock, talk to your dealer and we will special order what you need.
