This Wossner piston kit (Part No. 8007D100) is designed for the Kawasaki KMX 125 produced between 1986 and 2005. Featuring a 55.00mm bore size (+1.00mm oversize), the kit includes a forged piston built for strength, reliability, and efficient thermal performance. Manufactured in Germany, the piston is engineered with an elliptical profile to ensure a consistent bearing surface under heat expansion, minimising risk of collapse during operation.
