This Wossner piston kit features a 68mm bore size (67.94mm actual) and is designed for the 1986 Suzuki RM250. Manufactured in Germany, this forged piston is built for strength and thermal performance. Its elliptical design ensures even distribution of thrust loads during thermal expansion, reducing localised stress and helping prevent piston failure.
