Ensure your front end stays tight and aligned with this high-quality Steering Stem Nut. Designed to match the factory OEM specifications, this nut is...
Choose the bearing kit for the applicable steering assembly, then check the stem nut and washer. Their separate listings let you replace worn hardware without assuming it arrives in the bearing kit.
The conversion kit has a stated late-CB650SC application and includes upper and lower tapered bearing races. Confirm the frame and steering components before ordering after a front-end change. Follow the appropriate service instructions for installation and bearing adjustment rather than assuming the old setup applies unchanged.
Inspect the nut and washer separately
The stem nut is sold individually, with the washer available as its own product. Check the existing hardware and threads when planning bearing work. Replace what inspection requires, while avoiding an assumption that the conversion kit supplies these external fastening pieces.
Ordering questions
Does tightening the upper stem nut set the bearing adjustment?
The stem-nut guidance calls for setting bearing preload by the correct service procedure first, then fitting the correct washer and tightening the upper nut without disturbing that adjustment. Check for smooth steering with no notchiness, binding or play afterward; extra top-nut tightening is not a substitute for diagnosis.
Can an ordinary washer substitute if its hole fits the stem?
The specified washer’s thickness and seating surface affect the upper hardware’s clamping. Compare the original arrangement and reference 90503-425-000 rather than choosing by hole diameter alone. The matching nut and washer are separately supplied, so inspect both during steering service.
Can this kit be chosen by motorcycle year after a front-end swap?
Identify the fitted steering stem and frame bearing arrangement first. The year-specific listing alone does not establish compatibility for a mixed or modified front-end assembly.
