1978 Honda CB550K — Composants et amortisseurs de direction

The steering choices here center on the external stem nut and washer, with chrome and black nut options. Compare the fitted nut and retained washer before selecting the finish. Keep these fittings separate from fork-cap parts and from any bearing-service purchase you are planning.

1978 Honda CB550K · Steering Hardware & Dampers Buying guide

Check the stem fitting first, then choose its finish

The chrome and black nuts list the same reference pattern and 30 mm hex. Match the fitted assembly, then assess the separate washer; fork-cap O-rings and cap pairs address other fittings at the front end.

Make the finish decision after the reference check

Chrome and black are different appearance choices for the listed stem nut pattern. Both descriptions specify a 30 mm hex and reference 90304-415-000. Compare the installed fitting first, then choose the finish and assess whether the separately sold washer also needs replacement.

Keep cap seals apart from stem hardware

The fork-cap O-ring pair and custom cap pair concern the fork tops rather than the steering stem nut. Identify the exact front-end fitting needing repair before building the order. Replacing an external nut or washer should not be treated as a complete steering-bearing service package.

Common questions

Does the chrome nut come with its washer?

The chrome nut is sold individually and its description offers a matching washer separately. Inspect the retained washer and select it as another purchase if needed, rather than assuming a complete nut-and-washer set.

Is the black nut a different wrench size?

Both stem nut descriptions state a 30 mm hex. Check the fitting currently on the motorcycle before choosing a tool, then consider black or chrome as the finish choice within the listed reference pattern.

Are the fork-cap O-rings intended for the stem nut?

They are described as a two-piece fork-cap O-ring set referencing 94608-50000. The steering stem washer has a different reference and purpose, so identify the actual fitting instead of substituting nearby front-end parts.
