Piston Kit 57mm Bore 56.94 Wossner 8120D100 (+1.00)
YAMAHA YZ125 1984
Wossner forged pistons are superior in strength and design. Engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls. Elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distributing thrust loads more evenly, thereby preventing piston collapse. Made in Germany.
