1971 Honda CL450K4 Steering Stem Hardware

When replacing visible steering hardware on a 1971 Honda CL450K4, start with the fitted stem and the pieces already there. The nut’s hex size, its reference and the washer’s separate reference help organize the comparison without establishing thread compatibility by appearance.

1971 Honda CL450K4 · Steering Stem Hardware Buying guide

Check the stem connection before choosing the finish

The chrome nut is individually supplied and has a 30mm external hex. Its washer is offered separately. Compare both pieces with the retained steering assembly before deciding what the replacement order needs.

Use separate references for the nut and washer

The chrome nut carries 90304-415-000, while the chrome washer carries 90503-283-000. Each is supplied individually. Compare the removed components and the appropriate assembly information, keeping the washer’s condition and dimensions in the decision rather than assuming a new nut completes the order.

Treat finish as the last comparison

The linked Joker Machine black nut shares reference 90304-415-000 and the 30 mm hex with the chrome nut. Both explicitly cover the 1971 CL450. Choose the finish for the retained stem, and check the actual thread and mounting arrangement if the steering assembly has been changed.

Ordering questions

Is the 30mm number the nut’s thread diameter?

It identifies the external hex used by the tool. Establish the actual thread from the stem and suitable parts information before ordering; neither the finish nor the hex size proves the connection will match.

Is the washer included with the chrome nut?

The washer is offered as a separate, individually supplied product. If both pieces need replacement, assess the nut and washer independently and add the matching items to the order after checking their references.

Can the black alternative be chosen solely by its finish?

Both chrome and linked black nuts list this CL450 year and reference 90304-415-000. Choose the finish after identifying the retained stem. A substituted yoke or stem still needs its actual connection checked rather than relying on appearance.
