Wossner forged piston kit with a 47.00mm bore size (46.95mm actual), specifically designed for Yamaha YZ80 models from 1993 to 2001 with a US bore. Manufactured in Germany, this piston kit features an elliptical design to provide uniform bearing surfaces during thermal expansion, enhancing combustion chamber heat transfer and evenly distributing thrust loads to help prevent piston collapse.
Features
Forged piston construction for superior strength and durability
Engineered for effective heat transfer from combustion chamber to cylinder walls
Elliptical design promotes uniform bearing surfaces under thermal expansion
Reduces localised pressure and prevents piston collapse
Manufactured in Germany
