1978 Honda CB400TI Hawk I · Steering Hardware Buying guide

Check the top nut and washer as separate pieces

The nut has a stated 30 mm hex; that is its wrenching size. Its matching washer is sold separately, so check the condition of both before ordering.

Use the references without guessing the thread

The nut replaces Honda 90304-415-000 and the washer replaces 90503-283-000. The nut’s published 30 mm dimension describes its hex. If a different steering stem has been fitted, establish its thread and hardware requirements instead of inferring them from that wrenching measurement.

Inspect before buying a cosmetic replacement

A worn finish may justify replacement hardware, but steering movement or play calls for inspection of the assembly. Follow the correct service manual for adjustment and tightening specifications. A new chrome nut or washer does not by itself establish the condition of the steering bearings.

Buying questions

Does the chrome nut include its washer?

Order the washer separately when it is needed. The nut and matching chrome washer are sold as individual products, with separate Honda replacement references, so check both pieces before placing the order.

Does 30 mm describe the steering-stem thread?

No. It is the stated hex size of the nut. Match the nut to the correct steering stem and reference; do not use the outside wrenching dimension as a thread measurement.

Will this hardware fit a different upper triple clamp or stem?

Check the changed assembly’s requirements first. The Hawk I application supports the original-type arrangement, while a replacement stem or upper clamp can require different hardware even if the nut looks similar.

Not sure which part you need?

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