KYB 15-23 Yamaha YZ250 FX/ 16-19 YZ450 FX/15-19 WR250 F-450 F Service Kit Rear Shock

This KYB rear shock service kit includes all the necessary components to refresh the internals of your Yamaha YZ250 FX, YZ450 FX, WR250 F, or WR450 F's rear shock. Keeping your shock's seals and valving in good condition is key to maintaining proper suspension performance and control on the trail or track.

Inside this kit, you'll find the specific parts needed to replace worn-out seals and potentially some valving components, depending on the exact design of your shock. Fresh seals prevent oil leaks and keep dirt out, while updated valving can restore the damping characteristics that may have degraded over time. This helps ensure your suspension continues to absorb impacts effectively and provides a comfortable, controlled ride.

Regularly servicing your rear shock with a kit like this can extend its lifespan and prevent more costly repairs down the road. Refer to your Yamaha service manual for the specific procedures and torque specifications required for installation.
