KYB - 120223600101 - Rear Shock Piston O-Ring - '02-'24 Kawasaki and Yamaha KX85, YZ65
For '02-'24 Kawasaki and Yamaha owners rebuilding the rear shock, KYB's rear shock piston O-ring (120223600101) is a direct OE-spec fit. 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 '02-'24 Kawasaki and Yamaha models.
