Description

Your CR250R's performance is only as strong as its internal components—and a worn or undersized piston directly limits throttle response, combustion efficiency, and reliability. The Wiseco 431M07150 is precision-forged to exact tolerances, delivering the durability and thermal stability your vintage two-stroke demands, whether you're riding hard on the track or trail. This is the piston spec that separates consistent, powerful performance from gradual degradation.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
