1977 Honda CB550K · Steering Hardware & Dampers Buying guide

Choose bearing parts separately from stem fittings

The bearing conversion, stem nut and washer address different pieces of the steering assembly. Compare the kit description with the parts needed for the repair, then select the external fittings by reference and finish.

Check the conversion’s stated contents

The tapered-roller kit is described as a steering bearing conversion with upper and lower races. Compare those contents with the complete repair needed on the motorcycle. Do not assume every surrounding seal, nut or washer is included, and retain the distinction between bearings and external stem fittings.

Choose the nut finish after confirming the fitting

The black and chrome stem nuts share the listed reference pattern and a 30 mm hex specification. Check the existing assembly first, then choose the finish. The washer is offered separately, so inspect its condition and confirm which pieces will be supplied with the order.

Common questions

Does the bearing kit include all steering hardware?

Its description identifies the tapered-roller conversion and upper and lower races. It does not establish a complete package of every external nut, washer and seal. Compare the listed contents with the pieces needed for your repair.

What wrench size is listed for the stem nuts?

The black and chrome stem nut descriptions specify a 30 mm hex. Compare the nut actually fitted before selecting a tool, especially if earlier repairs or custom parts have changed the external fitting.

Are the two bearing-kit listings different conversions?

The two listings carry the same kit reference and matching descriptions. Check the stated contents and existing bearing arrangement rather than treating different product names as proof of a different conversion kit.

Not sure which part you need?

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