Description
Top-end wear is the silent killer of 2-stroke performance. The Wiseco PK1393 piston kit replaces worn cylinders and pistons with precision-forged components engineered to handle sustained high RPM loads without sacrificing power delivery. If you’re running a CR125R at the edge of its limits—whether on the track or trail—this complete kit delivers the reliability and performance consistency you need to stay competitive.
This is a full top-end rebuild solution. You’re getting forged pistons, rings, wrist pins, circlips, and gaskets in one package—everything necessary for a complete refresh. Wiseco’s high-silicone forged aluminum construction reduces thermal expansion while maintaining the strength required for aggressive 2-cycle combustion. Because these pistons are purpose-built for Wiseco rings, you get guaranteed seal quality and ring-to-piston compatibility that aftermarket combinations simply can’t match.
