1977 Honda CB750F · Gauge cables Buying guide

Cables for the fitted gauges

The selected products cover mechanical speedometer and tachometer cables plus plugs for unused drives. Match replacements to the instruments and drive assemblies actually fitted, especially on a custom build.

Cable length and connections

Speedometer cable 51-2304 is listed at 38.5 inches end-to-end, and tachometer cable 51-2406 at 24 inches. Compare the actual end fittings and inner-drive shape as well as the length needed by the fitted instruments.

Unused mechanical drives

The speedo gear plug closes the retained front-wheel speedometer-drive opening to help keep the gear clean. The tach-drive plug closes the mechanical tachometer-drive opening when the cable is no longer used, including a conversion to an electronic tachometer.

Cable questions

Does reference 37260-KB7-010 distinguish the two tachometer cables?

No. Both 51-2401 and 51-2406 list that reference and include the 1977 CB750F in their applications. Confirm the actual cable length and end fittings required by the fitted arrangement, and have the supplier confirm the offered cable’s measurements before choosing between them.

Can I choose between the two drive plugs by their 15 mm diameter alone?

No. Speedo gear plug 29-0538 is listed at approximately 15 mm outside diameter and 22 mm long for the retained speedometer-drive opening. Tach-drive plug 73-0884 includes an O-ring and is intended for a screw-retained opening approximately 15 mm in diameter with a 10.5 mm retaining groove. Match the actual drive opening and retention features, not diameter alone.
