This Wossner piston kit features a 67mm bore size (66.94mm actual) and is designed for the Suzuki RM250 model year 1986. Forged in Germany, this piston offers high strength and thermal performance. The elliptical profile ensures a uniform bearing surface under expansion, distributing loads evenly and helping prevent piston failure due to localised stress.
