Frequently Asked Questions

How many Honda 51447-KL4-951 fork-seal stopper rings are included?

Two metal stopper rings are included, enough for both fork legs on one compatible motorcycle because one ring is used above each fork oil seal.

Where does the fork-seal stopper ring install?

Honda OEM 51447-KL4-951 sits in the retaining groove above the fork oil seal. It is a metal retaining ring and does not replace the rubber oil seal or dust seal.

What should be checked before reusing the fork-leg retaining grooves?

Clean each groove fully and inspect it and the stopper ring for corrosion, distortion or incomplete seating. Confirm both rings snap completely into their grooves before filling the forks and reinstalling the front wheel.
