The Story

This Wossner forged piston kit with a 65.50mm bore (65.44mm actual) is designed for Yamaha two-stroke models such as the YFZ350 Banshee, RD350 variants, and the RZ350. Made in Germany, the piston features a forged design for enhanced strength and thermal performance. Its elliptical shape helps ensure even load distribution during expansion, reducing localised stress and minimising the risk of piston collapse.
