1980 Honda CB650 — Composants et amortisseurs de direction
Identify the steering bearings already fitted to your 1980 CB650 before ordering a conversion kit. The tapered kit and top stem hardware are separate products. Check whether previous work changed the bearing arrangement or stem, then match the repair parts to that actual assembly.

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 bearings and top hardware from the fitted stem
The kit includes upper and lower tapered bearing races. The separate stem nut and washer address external hardware, so inspect their condition rather than assuming a bearing package renews the whole steering assembly.
This is a tapered-roller conversion kit with upper and lower races. Check the current assembly and use the kit instructions with the service manual. A motorcycle already fitted with modified steering parts needs the interfaces checked before a stock-application kit is selected.
Order nut and washer individually
The washer references 90503-425-000 and the nut references 90304-425-000. They are separate individual products. Compare the retained hardware and its condition before purchase; a new bearing kit does not establish that damaged threads can be reused.
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 I fit the kit with a non-original stem?
Verify the stem and frame bearing interfaces first. The listed CB650 application does not establish compatibility with every swapped front end or modified stem.
