This Wossner forged piston kit with a 54.75mm bore (54.69mm) is designed for Suzuki RM125 models from 1981 to 1984. Manufactured in Germany, it provides enhanced durability and optimized heat transfer. Its elliptical shape ensures a consistent bearing surface during expansion, effectively distributing thrust loads and reducing localized stress to help prevent piston failure.
