The standard tool specifies a 24mm inside diameter and a 3/8-inch driver. The premium tool provides 20mm and 24mm diameters for use with a 1/2-inch-drive extension bar. Compare the nut engagement first, then check that you have the required drive equipment.
The locknut is sold individually under reference 90231-KCS-651, with CB92 1959–62 included in its application. Locate the nut in the correct parts diagram before ordering. Its 16mm designation and a tool’s working diameter describe different features, so do not equate them.
The standard tool uses a 3/8-inch driver. The premium dual-ended option is used with a 1/2-inch-drive extension bar. Choose the appropriate drive equipment and check access to the nut being serviced.
Compare the tool engagement with the nut itself. The locknut’s 16mm designation is not the same measurement as the tool’s stated working diameter; also check the retaining position and available access before selecting the tool.
Identify the installed assembly and its retaining hardware first. Use its parts references and working clearances to choose both the tool and locknut, rather than treating the motorcycle’s original model year as the only identifier.
