1976 Honda CB750F · Fasteners & hardware Buying guide

Factory hardware

The offered genuine Honda nut is 90231-KCS-651, sold individually. Confirm the replacement reference and its location in the fitted assembly before ordering; a broad product title does not mean every listed engine uses it in every named location.

Reference and location

The supplier asks buyers to confirm the part number and location in the motorcycle’s parts diagram or service manual, especially if the engine or clutch assembly has changed. Its commonly-one quantity applies where the nut is used; it is not a count for every location named in the title.

Genuine Honda

Honda 90231-KCS-651 is listed as superseding 90231-200-010, 90231-028-000, 90231-030-000, 90231-703-000, 90231-KCS-920, 90232-700-000 and 90231-200-000. Compare the required reference before ordering.

Lock nut questions

Where is the 16mm lock nut used?

The supplier describes compatible clutch-basket and oil-filter-rotor applications across multiple Honda models. Confirm the exact location and reference for your fitted assembly rather than assuming both locations apply to a 1976 CB750F.

Is it a genuine Honda part?

It is offered as genuine Honda part 90231-KCS-651, sold individually, with the earlier references listed as supersessions.

How many should I order?

The nut is sold individually and described as commonly one where used. Confirm the number of applicable locations being serviced before ordering; the product title does not establish a two-nut requirement.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
