1974 Honda CB550K · Steering Buying guide

Compare bearing conversion and bridge hardware separately

The nut’s 30 mm hex and reference identify one hardware choice; the washer is a separate sold-each item. The top-bridge kit supplies two washers at another location, distinct from the bearing conversion’s named races.

Keep the two washer products distinct

The top-bridge pack contains two washers referencing 53235-300-000. The chrome stem washer is a separate sold-each product referencing 90503-283-000. Use the original location and reference to choose between them, without assuming a washer for one position can substitute at the other.

Compare the bearing-kit contents

Two bearing-kit listings provide the same conversion description and named upper and lower races. A parenthetical number in a product title does not establish package quantity. Compare the supplied contents before ordering, and inspect the surrounding stem and bridge hardware separately.

Steering questions

Does the bearing kit fit the 1974 CB550K?

The description includes the 1974–77 CB550K and names upper and lower tapered bearing races. Nuts and washers have separate listings, so inspect those hardware needs independently rather than assuming they accompany the bearing conversion.

What size is the stem nut?

The chrome nut description states a 30 mm hex, reference 90304-415-000 and sold-each packaging. The matching chrome washer is offered separately; compare the existing washer before adding it to the nut purchase.

Are fork-cap O-rings steering-bearing components?

Their description identifies seals for fork caps, a different component from the steering conversion or stem hardware. They are not named as steering-kit contents, so keep any fork-cap sealing purchase tied to the actual fork repair.
