1973 Honda CB450K · Suspension & Wheel Buying guide

Identify each service area before combining the purchases

The steering kit states upper and lower tapered bearing races. Fork top bolt 90123-323-010 includes an O-ring and is sold each. Chrome stock-design shocks specify 321mm center-of-eye to clevis, while other shock families have different lengths and contents.

Parts to consider

Honda CB Steering Bearing Kit Upper and lower steering conversion racesJapanese-made tapered roller conversion kit with upper and lower tapered bearing races stated. Compare the installed steering assembly and confirm any additional seals or fastening pieces needed.View part 1971-74 Honda CB500K / CB450K / CL450K5 Front Fork Tube Cap Bolt with O-Ring ~ Replaces Honda OEM 90123-323-010 Fork top bolt with O-ring, sold eachAftermarket 90123-323-010 replacement with included O-ring.

Related parts: One rear hub seal, 34 × 55 × 9mm · Individual rear shock mounting bushing · Stock-type reflector with 6mm thread

Separate component fit from the chosen restoration appearance

Chrome stock-design shocks and a steering conversion kit address different assemblies with their own contents and measurements. Match the steering parts to the fitted assembly, and compare shock mounts and length independently. Their stated motorcycle applications do not establish a complete coordinated suspension package or document every modification already made.

Keep mounting measurements with their actual parts

The shock-to-swingarm bushing states 19mm length, 22mm OD and 10mm ID, while the rear seal measures 34 × 55 × 9mm. Identify each removed component before using those figures. Neither specification provides missing thread dimensions for the fork cap or mounting details for the separate screw-on reflector.

CB450K buying questions

Does the steering kit title ending “(2)” indicate another conversion specification?

Both kit listings have identical descriptions and the same part number. The suffix does not identify a different bearing dimension or an additional kit supplied. Compare the installed steering assembly and use the stated upper-and-lower race contents for purchase planning.

Is the fork top bolt sold individually with its O-ring?

Yes. The aftermarket top bolt replacing Honda 90123-323-010 includes an O-ring and is sold each. Count the fork-top positions being renewed before ordering. The description leaves thread diameter and pitch unstated, so confirm the fitted fork connection where its identity is uncertain.

What dimensions identify the rear shock mounting bushing?

The individually sold bushing replacing Honda 40548-268-000 measures 19mm long, 22mm outside diameter and 10mm inside diameter. It is described at the shock-to-swingarm mounting connection. Compare the removed component and count the matching bushings needed at that location.
