Description
A worn or damaged piston directly impacts combustion efficiency, throttle response, and overall engine reliability—especially critical on a high-revving 2-stroke like the CR125R. The Wiseco PK1257 is engineered to restore and exceed OEM performance with precision CNC machining and forged aluminum construction, while the included gasket set ensures a complete, leak-free rebuild without sourcing individual components.
