PISTON KIT 92-98 WR200 73.00, WOSSNER 8070D700 YAMAHA DIRT

Wossner Forged Piston Kit 73.00mm Bore. This Wossner forged piston kit is made for Yamaha DT200R (1988–1991) and WR200 (1992–1998) models, with a bore size of 73.00 mm and a piston diameter of 72.94 mm (+7.00 mm oversize). Designed for extreme oversize applications in 2-stroke engines, this forged piston offers robust structural integrity and optimised thermal dynamics. The elliptical design ensures even thrust load distribution, helping to prevent piston collapse during high-temperature operation. Precision-made in Germany. Features include forged piston construction for maximum durability, high-efficiency heat transfer from combustion chamber to cylinder walls, elliptical shape for uniform bearing surface and reduced localised pressure, and German engineering for consistent quality and precision.
