Description

This Wossner forged piston kit with a 66.00mm bore (65.94mm actual) is intended for Yamaha two-stroke engines, including the YFZ350 Banshee, RD350 series, and RZ350. Manufactured in Germany, the piston is built for strength, consistent performance, and efficient heat dissipation. Its elliptical design ensures even surface contact during thermal expansion, minimising stress concentrations and reducing the potential for piston failure.
