WÖSSNER forged piston, designed and manufactured in Germany for engine preparations and repairs on 2 and 4-stroke engines. Designed for demanding riders, this piston combines the strength of forging with a skirt finish treated for anti-friction to reduce wear and promote a clean and consistent engine response.
The geometry and treatment of the skirt limit friction in the cylinder, useful for roadster uses and small displacement motorcycles. This piston is suitable for maintenance or engine refurbishment operations when the specified bore diameter matches the requirement. Ideal for those replacing a worn part or installing a forged piston for greater mechanical strength without altering the stroke or original configuration.
Examples of common fits: YAMAHA DT 125 X SM (2005), KTM 125 STING (1999), YAMAHA DT 125 R (2005). Always check compatibility with your engine before installation.
