Description
The stock piston in your CR250R won’t cut it if you’re pushing for consistent power and reliability on the track or trail. Wiseco’s forged piston delivers the durability and compression needed to handle aggressive tuning while maintaining the tight tolerances that keep your two-stroke running strong. This is the rebuild component serious racers and tuners trust when reliability matters.
This complete piston kit includes everything you need for a fresh top-end: the forged piston, compression rings, wrist pin, and circlips. The high-silicon aluminum alloy and E-coated crown resist wear and heat cycling, while the optimized dome design maximizes combustion efficiency. Bolt-on installation—no custom fabrication required.
