Description
If you’re running a CR250R that demands reliability under race conditions or high-RPM trail abuse, a worn piston directly kills performance and invites catastrophic failure. The Wiseco 466M06600 delivers the precision bore diameter and material science your engine needs to sustain peak power without compromise. This is a straightforward bolt-in refresh that restores—or exceeds—original capability.
Built from high-silicon aluminum alloy and CNC-machined to exacting tolerances, this piston kit minimizes skirt friction while handling the thermal stress of sustained combustion. You get consistent ring sealing, improved throttle response, and the durability to survive repeated abuse on the track or in the dirt.
