1972 Honda CB500K Clutch Plates & Springs

Count the 1972 CB500K clutch components by type before ordering. The current listings specify seven friction plates and six steel Plate B discs, with each plate supplied individually. The four-spring product is already a set, so its order quantity is calculated differently from the plates.

1972 Honda CB500K · Clutch Friction, Steel & Springs Buying guide

Distinguish the installed plate count from the supplied quantity

Friction plates and steel discs alternate functions within the clutch and have separate replacement references. The 1972 steel application explicitly calls for six Plate B pieces. Read each supplied quantity before planning either a limited repair or a complete plate order.

Check friction and steel plates independently

The friction plate listing gives one supplied and seven required for the CB500K. The steel Plate B listing gives one supplied and six required for its 1972 application. These are not identical disc types. Inspect the existing stack and preserve the specified arrangement when planning which pieces to replace.

Springs do not make the plate order complete

The spring package supplies four matched springs; it does not include friction or steel discs. Read the plate pages separately when purchasing a complete clutch service order. If the motorcycle has a replacement engine or clutch, compare that installed assembly with the stated application before using the model’s counts.

Common questions

Which steel disc is listed for the 1972 CB500K?

Steel Plate B references 22321-KA4-700, with six pieces specified for the 1972–73 CB500K. One disc is supplied per order unit. Confirm the engine and installed clutch stack before counting replacements, especially where parts from another model have been fitted.

What quantities are needed for a complete friction-and-steel order?

The CB500K friction application requires seven plates, while the compatible 1972 steel Plate B application requires six. Both are individually supplied. Count them separately from the four-spring package, and match the installed stack before planning a full plate replacement.

What tradeoff does the matched performance spring package carry?

The source supplies four Japanese-made springs and advises fitting the matched set together. Firmer springs can increase lever effort and cannot repair glazed plates, distorted steels or basket wear. Check those components before treating spring replacement as the whole clutch repair.
