1973 Honda CB350G · Steering & Top Bridge Hardware Buying guide

Keep the stem and fork-clamp washers distinct

The chrome nut and stem washer are sold separately. The related top bridge kit supplies two fork-clamp washers. Match each piece to its position before ordering hardware for a stripped or previously modified front end.

Select the stem pieces individually

The nut replaces reference 90304-415-000 and the separate stem washer replaces 90503-283-000. Both are sold individually. Compare the existing assembly and reference numbers if the steering stem or top bridge was changed during an earlier restoration.

Preserve the correct clamp assembly

The related top bridge kit contains two washers corresponding to 53235-300-000. They serve the fork-clamp positions rather than the central stem. Follow the relevant service instructions for arrangement and tightening; replacement washers do not establish the condition of an already damaged bridge.

Buying questions

Does the steering stem nut include its washer?

The chrome stem washer is offered separately, and both products are sold individually. Inspect the existing washer and order it separately if replacement is required.

Does 30 mm describe the stem thread?

No. The product specifies a 30 mm hex size. Use the replacement reference and the original steering assembly to establish fit rather than treating the wrench size as a thread measurement.

How many top bridge washers are supplied?

The top bridge washer kit contains two pieces. They belong at the fork-clamp positions and are different from the single central steering stem washer shown alongside the kit.

Not sure which part you need?

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