PISTON KIT 84-85 KX80 49.00, WOSSNER 8201D100 KAWASAKI MX

This Wossner forged piston kit features a 49.00mm bore with a +1.00 oversize specification and is intended for Kawasaki KX80 models from 1984 to 1985. Precision-manufactured in Germany, the piston is designed for efficient combustion chamber heat transfer and optimal load distribution. The elliptical profile reduces the risk of localised pressure and piston failure, supporting reliable performance in two-stroke engine environments.
