1980 Honda CB400TA Hawk · Steering Bearings & Hardware Buying guide

Decide between bearing work and top-stem renewal

The bearing kit addresses the steering head. The nut and washer secure a different part of the assembly, so inspect each component and order to the work you are undertaking.

Identify the existing bearing arrangement

Honda’s original steering fiche uses ball races; the offered kit is a tapered roller conversion with upper and lower races. Check whether the motorcycle has already been converted before ordering. Use the conversion instructions and model service information rather than mixing assumptions from the two arrangements.

Choose the finish after confirming the reference

The chrome nut replaces Honda reference 90304-415-000 and is sold each. The matching chrome washer, reference 90503-283-000, is a separate item. The related Joker Machine nut offers a black, CNC-machined alternative with the same stated reference; compare the existing hardware before selecting a finish.

Questions before ordering

Is the bearing kit a replacement set of original loose balls?

It is a tapered roller bearing conversion, with upper and lower races. The original Honda arrangement uses ball races. Identify what is currently installed and follow the conversion instructions if changing bearing type.

Does 30mm describe the steering nut thread?

No. It is the external hex size given for the offered stem nuts. Use the replacement reference and the original stem application to choose the part; do not treat that measurement as a thread diameter or pitch.

Can I buy the nut without a bearing kit?

Yes. The chrome stem nut and washer are separate products, each sold individually. The related black Joker Machine nut is another finish choice. Inspect the bearing condition independently when deciding how much of the steering assembly to service.
