Compare current and older references

Honda reference 90231-KCS-651 supersedes 90231-200-010, 90231-028-000, 90231-030-000, 90231-703-000, 90231-KCS-920, 90232-700-000 and 90231-200-000. Use the full reference from your parts information and check the actual assembly position; similar size descriptions do not establish interchangeability.

Prepare for special-nut service

Identify the nut’s tool-engagement dimensions before selecting a removal tool. Its 16 mm designation does not specify every dimension needed to choose the tool. Use the appropriate service information for access, locking arrangements and tightening specifications rather than inferring those details from the replacement hardware description.

Common ordering questions

Is this a genuine Honda nut or an aftermarket replacement?

This is a genuine Honda nut, reference 90231-KCS-651. If your parts information shows an older number, compare it with the listed supersessions and confirm the assembly position before ordering.

How many locknuts are included?

One locknut is supplied per product unit. Count the locations being serviced and use the appropriate parts information to determine the quantity needed for the repair.

Will it fit if the engine has been replaced?

Identify the engine and assembly actually fitted, then compare reference 90231-KCS-651 with the applicable parts information. The motorcycle’s original model year cannot establish the hardware needed inside a substituted engine.

Not sure which part you need?

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