1968 Honda CB160 · Fasteners & Hardware Buying guide

Match the earlier Honda reference to the current locknut

Honda number 90231-KCS-651 covers the listed CB160 application and supersedes earlier locknuts. Reference matching is more useful than appearance when identifying the hardware needed for a particular engine assembly.

Follow a changed engine’s identification

A frame year cannot identify the internal hardware of a replacement engine. Use that engine’s assembly information to find the required reference, then compare it with the locknut’s replacement list. The explicit CB160 application covers 1966–69, while an altered assembly needs its own check.

Set the quantity for the positions being serviced

The locknut is sold individually. Count the required replacements from the specific repair instead of reading the combined clutch and rotor description as a fixed quantity per motorcycle. Keep the applicable service information available for the installation method and tightening specification.

Fasteners & Hardware buying questions

Which earlier references are replaced by this locknut?

Honda 90231-KCS-651 replaces 90231-200-010, 90231-028-000, 90231-030-000, 90231-703-000, 90231-KCS-920, 90232-700-000 and 90231-200-000. Match the complete reference from your assembly information rather than choosing by the shared 16 mm description alone.

How should I choose the quantity for clutch or rotor work?

Each item supplies one nut. Use the assembly diagram and the scope of your repair to count replacements. The combined application wording does not establish that every motorcycle uses one at each of those positions.

What should I check if the engine has been replaced?

Identify the installed engine and the assembly being opened, then obtain its required part number. Compare that reference with the current Honda number and listed supersessions before relying on the frame’s 1968 model year.

Not sure which part you need?

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