1983 Honda CB550SC · Steering Parts Buying guide

Assess bearing conversion and stem hardware independently

The bearing-kit application includes the 1983–84 CB550SC, while the nut and washer explicitly name 1983. Match the fitted assembly and each reference; a bearing-kit title does not establish that surrounding hardware is included.

Keep the nut and washer references together

The stem nut references 90304-425-000, while the washer references 90503-425-000. Both descriptions include the 1983 CB550SC, and the nut explicitly offers the washer separately. Compare the fitted hardware before ordering either item rather than assuming the nut purchase supplies both pieces.

Choose the conversion by its described contents

The bearing conversion description names upper and lower tapered races and the CB550SC application. Another listing repeats that description with a parenthetical number in its title; that number is not an explicit two-kit package statement. Review the named contents instead of deriving quantities from a numbered title.

Choosing parts for your CB550SC

Does the stem nut include its washer?

The nut description explicitly states sold individually, with the washer available separately. Their references are 90304-425-000 and 90503-425-000. Inspect the existing washer independently before adding it to a nut purchase.

What does the tapered conversion listing name as included?

It names upper and lower tapered bearing races and includes the 1983–84 CB550SC application. The nut and washer have separate listings, so assess those hardware needs without assuming they accompany the conversion.

Does a parenthetical number in the kit title mean two kits?

The numbered and unnumbered listings give the same conversion description and named upper and lower races. Neither explicitly states a two-kit package. Compare the supplied contents and confirm the order quantity instead of treating the title’s parenthetical number as a bundle.
