Piston Kit 86-88 YZ125 58.00, Wossner 8118D200 Yamaha MX

Description

This Wossner 58.00mm (+2.00 oversize) forged piston kit is designed for Yamaha YZ125 models from 1986 to 1988. Manufactured in Germany, the piston features a forged construction for maximum strength and durability. Its elliptical design ensures an even bearing surface during thermal expansion, helping to distribute thrust loads uniformly and prevent piston collapse. The design also facilitates efficient heat dissipation from the combustion chamber to the cylinder walls, making it suitable for high-performance two-stroke engine applications.
