1962 Honda CB92 · Fasteners & Hardware Buying guide

Connect the replacement number to the original hardware

The current fastener selection is one genuine Honda locknut. Reference matching is more useful than choosing by appearance, particularly when the removed nut is unmarked or a previous repair used different components.

Use the replacement references carefully

Honda number 90231-KCS-651 identifies the supplied locknut. The product information lists 90231-200-010 among the numbers it replaces. Match your original reference and assembly before ordering; that replacement list does not establish every possible clutch or rotor position on the motorcycle.

Build an enquiry from the diagram

An unreadable or missing old nut need not leave you ordering by resemblance. Identify the component in the correct parts diagram and retain its callout and reference. If the assembly differs from the diagram, provide those details before selecting the replacement hardware.

Replacement-hardware questions

Is this genuine Honda hardware or an aftermarket nut?

The supplied product is described as genuine Honda OEM hardware under reference 90231-KCS-651. It is sold individually, so the quantity in your order should reflect the confirmed positions being repaired.

Can I match an older reference such as 90231-200-010?

That number appears in the product’s replacement-reference list for 90231-KCS-651. Check it against the original assembly reference, particularly if the engine or retaining components have changed during the motorcycle’s service life.

Does the clutch-and-oil-filter-rotor name identify the exact position?

The name covers the locknut’s broader uses. Use the diagram for your fitted assembly to locate the required fastener; the CB92 application list does not specify an exact retaining position or a complete per-motorcycle quantity.
