1968 Honda CL450K1 · Suspension & Steering Buying guide

Choose the stem nut for the steering assembly fitted

This CNC-machined nut replaces Honda reference 90304-415-000 and explicitly covers CL450K 1968–74. It offers a black finish; identify any changed front-end components before relying on the motorcycle’s year.

Parts to consider

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

Check the assembly behind the model label

The nut has an explicit CL450K 1968–74 application. That supports an unchanged matching assembly; a different front end needs identification of its own. Compare the existing nut and stem rather than using the frame’s model year to select hardware for an unknown conversion.

Separate hex size from thread information

A 30mm hex describes the wrenching flats. It does not provide the thread diameter or pitch. If the fitted stem is uncertain, obtain the missing thread details before ordering instead of treating the hex measurement as a compatibility specification.

Common buying questions

Does 30mm describe the nut’s thread?

No. It is the hex size. The merchant does not publish the thread diameter or pitch, so identify the fitted stem before ordering for a changed front end.

Who makes this replacement nut?

Joker Machine. The nut is described as CNC-machined and made in the USA. The Honda reference identifies the part it replaces.

Can I order by the frame’s year after a fork swap?

Identify the steering stem now fitted first. The CL450K 1968–74 application does not establish compatibility with an unknown replacement front end.

Not sure which part you need?

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