Choose workshop tools to suit the fastener and the driver already on your bench. The clutch-nut tools offer different working ends and drive sizes. A separate genuine Honda lock nut is another ordering decision, matched to the assembly being serviced.

The two clutch-nut tools have explicit CB175K coverage and different drive arrangements. Confirm engagement and access at the fitted assembly, then use its service information to prepare the job.
The standard clutch tool has a 24 mm inside diameter and takes a 3/8-inch driver. The premium option provides 20 mm and 24 mm ends for a 1/2-inch-drive extension. Compare access and engagement at the fitted assembly instead of choosing only by the premium label.
Identify replacement hardware independently
The linked genuine Honda lock nut is supplied individually under reference 90231-KCS-651. Confirm its location using the parts information for the assembly being serviced. A nominal 16 mm nut description does not specify the complete thread or which tool profile it needs.
Buying questions
Does the premium clutch tool use the same drive?
No. The standard tool takes a 3/8-inch driver, while the dual-ended premium tool is used with a 1/2-inch-drive extension. Choose the drive and working end that match your verified service setup.
Is the 16 mm lock-nut description enough to choose a tool?
No. Match the nut’s engagement profile to the working end of the tool. The nominal nut size and the tool’s stated working diameter describe different features, so check the assembly and access before ordering.
Do I need both clutch-nut tools for one motorcycle?
Do not assume so. Compare the actual fastener profile, available access and the driver you own. The two tools offer different drive and end arrangements, rather than a documented two-tool requirement for this motorcycle.
