1979 Honda CB400TII Hawk II · Steering Stem Hardware Buying guide

Pair the top stem nut with its washer

The nut replaces 90304-415-000 and the washer replaces 90503-283-000. Honda specifies one of each in the 1979 top-bridge assembly; both replacement products are sold individually.

Decide whether both pieces need renewing

The top nut and washer have separate Honda references and are purchased separately. Inspect the washer as well as the visible nut when planning a cosmetic refresh. One nut and one washer match the original 1979 top-bridge arrangement.

Keep hardware replacement separate from adjustment

A new top nut or washer renews that part of the assembly. Steering stiffness or play needs the appropriate inspection rather than a cosmetic parts swap alone. Follow the Honda manual for steering bearing checks, adjustment and final fastening requirements.

Steering Stem Hardware questions

Does the chrome nut come with its washer?

The washer is sold as a separate product. Order one of each if renewing both parts in the original assembly, or select only the piece that requires replacement.

What does the 30mm nut measurement mean?

It is the hex size for the outside of the nut. It does not specify the thread diameter or pitch. Use the application and reference number when checking suitability for the original steering stem.

Will these fit a different top bridge?

A changed front end may use another stem or fastening arrangement. Compare its nut and washer requirements before ordering. The original CB400TII application does not establish compatibility with the donor assembly.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
