KYB 14-23 Yamaha YZ250-450 FX/ WR250-450 F Service Kit Rear Shock 50 mm. / 16 mm.

This KYB service kit gives you the essential components to rebuild the rear shock on your 2014-2023 Yamaha YZ250-450 FX or WR250-450 F. It includes the parts needed to refresh the internal seals and O-rings, helping to restore proper damping and prevent leaks.

Inside this kit, you'll find the specific seals and O-rings designed for the 50mm rear shock body and 16mm shaft found on these Yamaha models. Keeping your shock's internals in good shape is key to maintaining consistent suspension performance, especially after a lot of riding. A worn seal can lead to fluid loss and a spongy feel, so replacing them with a well-built kit like this can make a noticeable difference in how your bike handles rough terrain.

When you're rebuilding your rear shock, it's a good idea to have some specialized tools on hand, like a shock vise and seal driver, to make the job go smoothly. Always refer to your Yamaha service manual for the correct procedures and torque specifications.
