1971 Honda CB450K · Clutch Plates & Springs Buying guide

Match each plate type and calculate its purchase separately

The CB450K application states seven friction pieces and six steel pieces. Those counts do not expressly describe full supplied packs. The 16mm tab washer references Honda 90431-292-000 as a separate component; these listings do not identify a spring package.

Parts to consider

Honda CB Steel Clutch Plate ~ Replaces 22321-MG8-000 Steel plate with six-per-bike countReferences Honda 22321-MG8-000 / 22321-283-000. Six pieces are stated per CB450K application. Confirm how many pieces the purchase supplies rather than treating the listed application count as a six-piece pack.View part Honda CB Clutch Friction Plate ~ Replaces 22201-MA7-000 Friction plate with seven-per-bike countReferences Honda 22201-MA7-000 / 22201-283-000.

Use the references to keep plate types distinct

Friction plates list 22201-MA7-000 / 22201-283-000, while steel plates list 22321-MG8-000 / 22321-283-000. Compare the corresponding removed component before ordering. If the clutch has been changed, confirm its identity instead of assuming the original model’s counts identify the altered assembly.

Assess locking hardware as its own repair component

The washer description gives a 16mm size label and reference 90431-292-000, without complete dimensions. Compare it with the existing washer and clutch hardware. The plate descriptions do not name a washer or springs as included, so assess those needs separately rather than reading the group as a complete rebuild package.

Questions to help choose the repair parts

How should I calculate a full set order from the listed counts?

First confirm how many pieces each plate purchase supplies. Then use the stated seven friction and six steel pieces for the identified CB450K application, or the verified requirements of a changed clutch. The per-bike figures are not explicit package quantities.

Can the washer’s 16mm label identify every needed dimension?

The description does not say which measurement the label represents or provide a complete drawing. Compare reference 90431-292-000 and the removed washer, then confirm any additional dimension required by the retained or modified clutch hardware.

Does selecting both plate types also supply the other clutch service parts?

The descriptions identify the friction and steel plates separately, without listing springs or a tab washer as supplied. The washer has its own product. Build any wider repair order from the components actually required and their individual contents and quantities.
