The Wossner 8101DA piston kit is designed for Yamaha YFS200 Blaster models from 1988 to 2006, featuring a standard 66.00 mm bore. Manufactured in Germany from high-strength forged material, this piston provides excellent durability and heat transfer efficiency. Its elliptical design promotes a uniform bearing surface during thermal expansion, helping to prevent localised pressure and reduce the risk of piston collapse. The kit includes all essential components for a reliable engine rebuild.
