Wossner Piston Kit 8116DA is a standard-size forged piston specifically designed for Yamaha YZ125 models from 1994 to 1996 with a 54.00mm bore. Manufactured in Germany, this piston offers enhanced structural integrity and optimal heat dissipation. Its elliptical profile promotes an even bearing surface under thermal expansion, minimising localised stress and helping to prevent piston failure under high-performance conditions.
