1972 Honda CB450K · Swing Arm Parts Buying guide

Use the stated bushing dimensions at the shock connection

The shock bushing is 19mm long with 22mm OD and 10mm ID. Bronze thrust bushings, pivot felts and metal caps are separate two-piece sets with different references. Pivot locknut, washer and grease fittings have their own contents.

Identify what remains outside the pivot fastening purchase

The locknut-and-washer product names 90354-268-000 and 90526-268-000, without a pivot bolt or sleeve described as included. Inspect those retained parts and the sealing arrangement before ordering. Felts, caps and bushings are separate products whose two-piece packages do not define one complete pivot overhaul kit.

Check the grease fitting connection before selecting by quantity

The nipple product supplies two against reference 96201-30001, with the label A .45 rather than a complete thread specification. Compare the fitting and mounting point actually present. Confirm missing connection details where the swingarm or fitting was changed, instead of interpreting that label as a measured thread or angle.

CB450K buying questions

Which dimensions belong to the rear shock mounting bushing?

The 40548-268-000 bushing is listed at 19mm length, 22mm outside diameter and 10mm inside diameter, sold individually. Those dimensions apply to the shock-to-swingarm connection. Identify the separate pivot bushings by their own references and measurements.

Do the metal end caps supply the left and right felts too?

The cap product supplies two metal pieces against 52144-283-010. Left and right felts are separately listed under 52145-283-000. Inspect both types and plan replacements by component rather than treating the cap purchase as a combined sealing set.

Does the grease fitting’s A .45 label document the mounting thread?

The description gives that label and reference 96201-30001 but no complete thread dimension. Compare the original fitting and the swingarm connection, then confirm the required specification when needed. Do not derive a thread size or mounting angle from the ambiguous label.
