Wiseco Piston Kit 57mm Oversize for Yamaha DT125 1974-1981 236M05700

A worn or damaged piston directly compromises your DT125's combustion efficiency, throttle response, and engine longevity. The Wiseco 236M05700 restores full power output and reliability with precision-engineered geometry and aerospace-grade materials built to handle sustained high RPMs. Whether you're chasing track times or tackling rough terrain, this complete kit delivers the durability and performance you need without compromise.

This piston kit includes everything required for a proper rebuild: the piston itself, ring set, wrist pin, and circlips. The 57mm bore is precision-honed to OEM+ tolerances, and the high-silicon aluminum construction resists thermal stress while keeping rotating mass minimal. CNC-machined tolerances ensure consistent compression and reduced blowby, translating to better fuel economy and easier cold starts.
