1982 Honda CB750SC · Clutch Lock Nut Buying guide

Identify the clutch’s retaining nut

The genuine Honda nut carries reference 90231-KCS-651 and a 16mm specification. Match the exact clutch position and replacement references, particularly when the motorcycle has had internal clutch components changed during earlier repair work.

Match the individual locking part

The featured nut is an individual genuine Honda component, rather than a complete clutch hardware kit. Compare its listed replacement references with the nut being removed. Keep the clutch’s surrounding washers and securing pieces identified separately so the order reflects the actual assembly.

Check altered clutch assemblies

An engine swap or previous clutch repair can leave hardware that differs from the motorcycle’s original specification. Identify the fitted assembly before ordering. Use the applicable Honda service procedure for locking and tightening rather than selecting a substitute by nominal nut size alone.

Clutch lock nut questions

Is this a genuine Honda part?

How many nuts are supplied?

It is sold individually. Identify the retaining position being serviced and inspect the existing hardware before ordering; a general per-bike quantity should not replace checking the actual assembly.
