The tapered kit supplies upper and lower bearing races for its listed application. The nut references 90304-425-000 and the washer 90503-425-000; identify worn or missing hardware separately from the bearing replacement.

The upper and lower tapered bearing races belong to the steering kit. The stem nut and washer have their own entries and are sold individually. Inspect all these parts before ordering so replacing bearings does not overlook damaged or missing fastening hardware.
Part references identify what can be purchased, but do not specify the steering adjustment. Follow the appropriate service information and supplied bearing instructions. A changed stem or complete front-end conversion requires its own dimensional and compatibility checks before selecting the kit.
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.
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.
Identify the actual stem, bearings and frame arrangement before ordering. A standard CB650C application does not verify the dimensions of every custom front-end combination.
