1971 Honda CB500K Clutch Plates & Springs

The 1971 CB500K clutch listings separate individual friction plates, individual steel Plate B discs and a four-piece spring set. Check the steel plate’s engine-number restriction before ordering. The number required in the clutch is not the quantity supplied in each listing.

1971 Honda CB500K · Clutch Plates & Springs Buying guide

Check the steel-plate restriction before counting pieces

The friction listing calls for seven plates on the CB500K. The steel Plate B listing calls for six on its compatible application and limits 1971 fitment to engine number 1018727 or earlier. Springs come as four pieces.

The engine cutoff matters on the steel plate

The current steel Plate B source limits its 1971 CB500K application to engine number 1018727 or earlier. Do not extend that claim to a later-numbered engine from the model year alone. If the engine or clutch has been replaced, confirm the installed assembly before choosing the plate.

A required count does not make a pack

The friction and steel listings explicitly supply individual plates. Seven friction plates are required for the listed CB500K clutch, while six Plate B discs are specified only for the compatible steel-plate application. The spring listing is a four-piece set, so quantity calculations differ between these products.

Common questions

How many individually ordered plates make the listed clutch stack?

The friction listing specifies seven plates for a CB500K. The compatible steel Plate B application uses six discs, but its 1971 engine restriction still applies. Both products are sold individually; count the pieces being replaced rather than ordering one presumed plate kit.

Does the steel Plate B fit every 1971 CB500K engine?

The detailed application limits 1971 fitment to engines up to number 1018727. One disc is supplied, with six required for that compatible clutch. Check the actual engine number and fitted stack; later 1971 engine fitment is not established.

What should I consider before choosing the performance spring set?

One Japanese-made package supplies four matched springs, with the source calling for installation together. Firmer springs can increase lever effort and do not remedy glazed friction plates, warped steels or a notched basket. Evaluate those components separately before selecting springs.
