Plan the hardware order around the assembly being serviced
The featured Honda locknut has a stated 1966–69 CB160 application. Match its reference to the assembly on your engine, particularly if parts have been replaced or the engine differs from the motorcycle’s original equipment.
A useful hardware order records the engine identification, assembly location and required part reference together. This genuine Honda nut replaces several earlier numbers, including 90231-200-010 and 90231-028-000. Use those references when reviewing an older parts book rather than choosing a nut by appearance alone.
Order for the positions being serviced
The locknut is supplied individually. The combined clutch and oil-filter-rotor description covers different applications, so it does not establish how many you need for this CB160 repair. Check the identified assembly and use the relevant service manual for installation tools and tightening instructions.
Tools & Hardware questions
Is the featured locknut genuine Honda or aftermarket?
It is a genuine Honda part, identified as 90231-KCS-651. Keep that reference with your order so you can compare it with the engine parts information and the assembly you are servicing.
What if my engine or clutch assembly has been replaced?
Use the identification and parts information for the components now fitted. Provide those details with the old part reference when asking about the nut; the motorcycle’s registration year cannot identify a substituted assembly.
Does the order quantity cover every locknut on the motorcycle?
No fixed motorcycle-wide quantity is established here. Each ordered item supplies one locknut; count the verified positions included in your repair before buying rather than assuming the combined application description means a multi-piece set.
Not sure which part you need?
Send your model and year, plus photos of your existing part and any changes to the original setup.
