Description
If you’re running a YZ125 hard on the track or trail, piston wear is inevitable—and a failing piston means catastrophic engine damage. The Wiseco 56.00 mm Oversize Piston Kit restores your engine’s compression and power while delivering the durability professional racers demand. This is a direct replacement built to handle sustained high-RPM abuse without compromise.
Wiseco engineered this kit with high-silicon aluminum that resists thermal stress, backed by their proven Electra coating for heat protection and ArmorGlide friction reduction on the skirt. You’ll see faster throttle response and improved horsepower the moment you fire it up, with the reliability to back it through multiple seasons of competitive riding.
