Wiseco Piston Kit Yamaha DT125 1974-1981 56.5mm Bore 236M05650

If you're running a DT125 that sees serious trail or track time, piston wear is inevitable—and a worn piston kills compression, throttle response, and fuel efficiency. The Wiseco 236M05650 delivers OEM-grade reliability with measurable performance gains through its high-silicon alloy construction, which resists detonation and thermal stress better than stock. Since it ships complete with rings and circlips, you're looking at a straightforward rebuild without hunting down separate components.

Wiseco engineered this kit specifically for the demands of both recreational and competitive riding. The lightweight design sharpens engine response across the RPM range, while the precision-machined geometry ensures consistent ring seal and minimal blowby. Whether you're refreshing a tired top end or building a refreshed powerplant, this piston gives you confidence that your engine will deliver consistent performance mile after mile.
