Description
The Wossner Piston Kit is engineered to restore or exceed your CRF450R’s power output while delivering the durability required for sustained high-RPM operation. A complete piston replacement addresses wear that reduces compression, throttle response, and overall engine efficiency—critical whether you’re racing competitively or pushing hard on the trail. Wossner’s FEA-optimized design and proprietary forging methods ensure you’re installing German-precision engineering, not a generic aftermarket compromise.
