KYB - 120105200101 - Rear Shock Bladder - '06-'24 Kawasaki, Yamaha, and Suzuki YZ250FX, YZ450FX, WR450F
KYB built the 120105200101 rear shock bladder to the same specification as the factory part it replaces on '06-'24 Kawasaki, Yamaha, and Suzuki models. A shock bladder separates the shock's oil from its pressurized nitrogen charge, keeping the two from mixing under hard use so damping stays consistent instead of foaming and fading. Once a bladder starts leaking or hardening with age, the shock loses that separation and performance drops off fast, which is why this OE-spec replacement exists — a direct fix for '06-'24 Kawasaki, Yamaha, and Suzuki models rather than a full shock replacement.
