Description
A worn or damaged piston directly kills your YZ125’s throttle response and engine reliability. The Wossner 8118DA replaces all critical internals—piston, rings, pin, and clips—in one complete kit, restoring factory performance or building a platform for modifications. Built to German precision standards, this forged aluminum piston handles the thermal and mechanical stress of 2-stroke racing without compromise.
