Wossner Honda CR125R 1987 Single Ring Piston Kit 8126DA

If you're running a CR125R at the track or trail, piston wear directly impacts throttle response, compression, and reliability—and a worn OEM piston robs you of both power and longevity. The Wossner 8126DA replaces your stock piston with a precision-forged unit engineered specifically for 2-stroke demands, delivering sharper power delivery and extended service life. This is a complete bolt-on kit, so you get everything needed for installation without sourcing individual components.

Wossner's German engineering leverages finite element analysis and proprietary forging techniques to optimize every aspect of this piston. The 4032 T6 aluminum alloy withstands the extreme temperatures and pressures of 2-stroke combustion, while the permanent skirt coating reduces friction and piston rock—translating to quieter operation and measurable gains in throttle response. Whether you're a weekend warrior or serious racer, this kit is the foundation of a responsive, durable top end.
