Description

Wossner Piston Kit 8188D200 is a forged performance piston designed for Yamaha YZ80 models from 1993 to 2001, featuring a 49.00mm bore (+2.00 US Bore). This German-manufactured piston offers excellent thermal management and mechanical reliability. Its elliptical profile provides a consistent and uniform bearing surface during thermal expansion, minimising high-stress zones and reducing the risk of piston collapse during intense use.

Features

  • Forged construction delivers high durability and strength under extreme load
