Buying questions

Is this a genuine Honda part?

Yes. The current product is identified as genuine Honda 90231-KCS-651. Its 16mm lock-nut application includes CB175K 1969–73; match the specific repair position before ordering.

What if my parts information shows an older lock-nut number?

Compare it with the listed earlier references, which include 90231-200-010, 90231-028-000 and 90231-030-000. A matching replacement reference should still be checked against the actual assembly, particularly after an engine or clutch change.

Is it sold as a pair or one nut?

It is sold individually. Order for the confirmed repair positions in the fitted assembly, using its parts information to establish how many matching nuts are needed.
