1966 Honda CB450K · Suspension & Wheel Buying guide

Choose the component that matches the work planned

The steering washer and wheel bearing are individual component listings; the bronze bushings are an explicit set of two. The rear shock choices are 290mm custom shorty sets and require a separate mounting assessment.

Check the specification at the component

A wheel or steering conversion may change the parts your motorcycle needs. Read the bearing marking and compare the removed steering washer with the listed reference. The model-year application helps identify the catalog part, but it does not verify every previously modified assembly.

Read custom mounting details before selecting shocks

The eye-to-clevis shocks list a 12mm ID × 21mm upper bushing. The eye-to-eye version lists 10mm ID × 21mm bushings at both ends. Compare these distinct mounting arrangements and the 290mm measurement with your build before choosing black or chrome.

CB450K buying questions

What should I compare before ordering the steering stem washer?

The washer replaces Honda 90503-283-000 and is sold individually. Compare the removed washer and fitted stem, especially after a front-end conversion. The listing gives no complete dimensions; bearings and a stem nut are not listed as supplied.

What should I check first for a wheel or swingarm conversion?

Use the components actually installed: compare the front bearing code, and confirm the swingarm bushing dimensions your assembly needs. The bushing description does not provide dimensions to validate an altered swingarm solely from the listing.

Do the available rear shocks establish stock CB450K fit?

The shock listings identify 290mm shorty sets for custom applications. Check length, upper and lower mounting arrangements and available clearance; their placement in the CB450K catalog does not establish a direct stock replacement.

Not sure which part you need?
