Choose the stem nut finish and matching washer

The chrome replacement and black Joker Machine nut reference 90304-415-000, with a 30 mm hex. The washer references 90503-283-000 and is supplied separately; inspect the fitted stack before choosing which parts to replace.

Choose the finish after identifying the stem

Both featured nuts list the CB550F application and the same 90304-415-000 replacement reference. The chrome nut is offered as a replacement; the black nut is made in the USA by Joker Machine. Compare the fitted stem and nut before ordering, particularly when the upper yoke or complete front end has been changed.

Check the washer and the surrounding assembly

The featured 90503-283-000 washer is sold individually. Inspect it with the nut and existing upper stem arrangement before deciding what to replace. These pieces do not establish steering bearing condition or correct adjustment; use the appropriate Honda service information for the fitted steering assembly rather than treating a new nut as the entire repair.

Steering Stem Hardware FAQs

Does the chrome or black stem nut include the washer?

The matching washer is a separate featured product, sold individually. Compare the existing washer and nut before ordering. Both nut choices reference 90304-415-000; the washer has its own reference, 90503-283-000, and serves a separate place in the assembly.

Is the black nut genuine Honda stock?

It is a Joker Machine replacement, CNC-machined and made in the USA, with a 30 mm hex and reference 90304-415-000. Choose it for the described black finish after confirming the fitted stem; it is not described as a genuine Honda part.

Can these nuts be chosen for a replacement upper yoke by hex size alone?

The 30 mm dimension describes the hex, not the thread compatibility. Check the replacement yoke and stem hardware specifications against the required nut reference. A converted front end needs that comparison even when its visible nut is the same wrench size.
