1968 Honda CL450K1 Steering Stem Nuts

For a black-finish steering-stem replacement on a 1968 Honda CL450K1, this Joker Machine nut explicitly covers the model. Check reference 90304-415-000 and the steering assembly fitted; the published 30mm dimension is the hex size, rather than a thread specification.

1968 Honda CL450K1 · Steering Hardware Buying guide

Check the stem hardware behind the black finish

The USA-made, CNC-machined nut is a finish and hardware choice for the steering stem. Match its replacement reference and application before buying, particularly where the fork assembly has been changed.

Parts to consider

Honda CB Black Steering Stem Nut ~ Joker Machine ~ Replaces 90304-415-000 Black Joker Machine steering stem nutCNC-machined in the USA, with a 30mm hex. Replaces reference 90304-415-000 and lists CL450K 1968–74.View part

Identify a changed steering assembly

With an unchanged matching assembly, the explicit CL450K application gives a useful buying reference. If the front end has been replaced, identify its stem and compare the existing nut. Obtain thread details for an unfamiliar assembly rather than working backward from the hex size.

Choose the finish deliberately

This is a black Joker Machine part, CNC-machined and made in the USA. Choose that finish to suit the project. The Honda replacement reference identifies its intended role but does not establish a genuine Honda part or a factory-original finish.

Common buying questions

Is the 30mm measurement a thread specification?

No. The stated 30mm dimension describes the hex. Thread diameter and pitch are not supplied, so obtain them when assessing an unfamiliar steering stem.

Is this a genuine Honda steering stem nut?

It is a Joker Machine replacement made in the USA. The Honda reference identifies the original part it replaces; it is not a claim that Honda manufactured this nut.

Can I choose it by model year after a front-end swap?

Identify the steering stem now fitted before ordering. The CL450K 1968–74 application does not verify a different front end, even when the motorcycle’s frame remains a 1968 CL450K1.

Not sure which part you need?

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