KYB - 120224000101 - Rear Shock Piston O-Ring - '91-'24 Yamaha and Kawasaki KX500, YZ85, YZ80
KYB's rear shock piston O-ring (120224000101) is a direct OE replacement for '91-'24 Yamaha and Kawasaki models. This small O-ring seals the piston assembly inside the shock body, and it's one of the first things to harden and leak as a shock ages. Left unreplaced during a rebuild, it lets oil bypass the piston and the damping goes soft and inconsistent — a cheap, easy-to-overlook part that matters more than its size suggests on '91-'24 Yamaha and Kawasaki models.
