Start with the genuine Honda replacement hardware shown here. Its current part number and earlier references help identify the correct nut; the service instructions for the fitted assembly determine the equipment needed alongside it.
Write down the required nut number from the assembly information before ordering. Honda 90231-KCS-651 replaces several earlier numbers, including 90231-200-010 and 90231-028-000. Match the exact reference, especially where an engine or internal assembly has been changed during the motorcycle’s life.
Choose the tools from the service procedure
The 16 mm product description identifies the locknut; it does not specify a removal tool or tightening value. Use service information for the assembly being repaired to arrange the necessary equipment. Keep the number of nuts ordered separate from any tool or accessory requirements.
Tools & Hardware buying questions
Is the featured locknut a genuine Honda part?
Yes. It is genuine Honda hardware under number 90231-KCS-651, with CB160 application from 1966–69. The product covers clutch-basket and oil-filter-rotor applications across several models; match your specific assembly reference when ordering.
What if my parts information uses an earlier number?
Compare it with the replacement list on the product page. The current nut supersedes seven earlier references. An exact match is useful ordering evidence; a similar-looking nut or the same nominal size is not a substitute for that check.
How do I prepare an order when the engine has been changed?
Use the installed engine’s identity and assembly information to find the required nut reference. Confirm that reference against the current number or listed replacements, then count the positions included in your repair.
Not sure which part you need?
Send your model and year, plus photos of your existing part and any changes to the original setup.
