1968 Honda CB450K · Clutch Plates & Springs Buying guide
Friction and steel plates carry different Honda references. A 16mm tab washer adds another component choice. None of these descriptions establishes a complete clutch kit with springs, seals or every fastener required by the repair.
Clutch friction plateFriction plate referencing Honda 22201-MA7-000 / 22201-283-000. Seven are stated as used for this application; confirm the supplied order quantity instead of reading the application count as a pack.View part
Steel clutch plateSteel plate referencing Honda 22321-MG8-000 / 22321-283-000. Six used per CB450K are stated in the listing. Confirm package quantity before ordering the required number of replacement pieces.View part
16mm clutch tab washerTab washer listed as 16mm, referencing Honda 90431-292-000. Match the removed washer and fitted clutch; the description does not define a full hardware kit or provide a complete dimensional drawing.View part
The friction listing states seven pieces used per CB450K, and the steel listing states six. Confirm the package quantity for each item before calculating the order. Do not carry counts from another model in the broader listing into this motorcycle, or assume that a singular plate title proves how many are supplied.
The tab washer is described as 16mm with reference 90431-292-000. The description does not define whether that size is an internal diameter or give a complete drawing. Compare the removed washer and confirm any dimension needed for an altered clutch rather than guessing from the short size label.
The application states seven used, but does not unambiguously define the supplied package count. Confirm what one order contains before buying for the whole clutch. Apply the same check to the steel listing, which states six used for the CB450K.
The description gives a 16mm size without defining that measurement. Use reference 90431-292-000 and the removed washer to confirm the application, and ask for any missing dimension rather than treating the label as a complete dimensional specification.
The descriptions identify friction and steel plates, with the tab washer separately listed. They do not state that springs are included or describe a complete clutch service kit. Source other components according to the actual repair requirements.
