Prepare the right engine hardware before dismantling
The supported hardware choice here is a genuine Honda locknut with a listed CB160 application. Its part reference identifies the replacement; the job being undertaken determines the service position, quantity and tools you will need.
Identify the hardware before assembling a tool order
The 16 mm figure describes this locknut; it is not a tool-size instruction. Use the service information for the engine assembly to establish the required removal tool and installation procedure. Keeping the old part reference with the job details helps distinguish replacement hardware from workshop equipment.
Keep the order tied to the worn part
Each item ordered supplies one Honda locknut. Inspect the hardware being replaced and check the assembly’s parts information before deciding the quantity. The product covers clutch and oil-filter-rotor applications across several Honda models, so that broad description should not become a two-nut order for this bike.
Tools & Hardware questions
Is this genuine Honda hardware or an aftermarket alternative?
It is supplied as genuine Honda hardware under reference 90231-KCS-651. The application includes the 1966 CB160. Match that reference or its listed replacement-number chain to the assembly on your motorcycle.
Should I order one for the clutch and one for the oil-filter rotor?
Order for the actual service position being repaired. The product is sold individually, and its combined application description covers multiple Honda assemblies; it does not establish a two-piece requirement for every CB160.
Does the 16 mm description identify the tool I need?
Use the assembly’s service procedure to select the tool. The product’s 16 mm designation does not provide a socket size, tightening value or removal method, particularly if the engine components have been changed.
