Wossner Piston Kit 89.92mm Honda CR500R 1985-2001 8229D100

If you're running a Honda CR500R, your piston kit directly determines how much power you can reliably extract from your engine—and whether that power translates to consistent performance across the RPM range. The Wossner 89.92mm Piston Kit is engineered to tighten tolerances, reduce friction losses, and handle the thermal stress of sustained high-RPM operation. This is the kind of precision upgrade that separates engines that last from engines that fail.

Built from aerospace-grade aluminum alloy and finished with a permanent skirt coating, this kit minimizes piston rock and friction—meaning quieter operation, better ring seal, and improved power delivery. The included rings, pin, and clips make installation straightforward, and the optimized weight-to-strength ratio ensures your engine responds instantly without sacrificing durability.
