1978 Honda CB750K · Cables Buying guide

Match the cable to its instrument and routing

The two replacement cables connect different instruments. A clamp retains the tachometer cable, while drive plugs are accessories for a different instrument arrangement. Start with the existing cable and confirm its required replacement length.

Parts to consider

Black speedometer cableJapanese-made black speedometer cable, listed at 40.75 inches and replacing 44830-356-000 and 44830-426-830; confirm the measurement convention and required reach.View part

Black tachometer cableJapanese-made black tachometer cable replacing 37260-149-000, 37260-KB7-010 and 37250-149-000. The listing gives 29 inches but also places 700 mm beside one reference; clarify the measurement before ordering.View part

Match the cable references and end connections

Compare the removed cable with the listed replacement references and both end fittings. A relocated gauge can need a different reach even when the original cable reference is identified; check the intended route before choosing the replacement.

Buy a drive plug for its stated purpose

The tach-drive block-off listing describes closing the drive opening when the cable is removed, including custom arrangements using an electronic tachometer. It does not connect or operate a cable-driven instrument. The speedometer gear plug is a separate accessory; compare its stated dimensions with the opening you intend to address.

Common questions

Which tachometer cable length should I use from the listing?

The product states 29 inches and separately shows 700 mm beside reference 37260-149-000. Those are not equivalent lengths, and the description does not explain the difference or measurement convention. Ask for the actual supplied length and compare it with the required cable route before ordering.

What should I check if the gauges have been relocated?

Confirm both end connections and the required routing with the gauges in their intended positions. The speedometer listing gives 40.75 inches without defining its measurement convention. Resolve the tachometer listing’s two length figures as well; model-year application alone does not establish reach for a changed layout.

What fitting details matter when choosing the tach-drive block-off plug?

Its listing describes approximately 15 mm-diameter cable fittings with a 10.5 mm groove, held by a screw. Compare the removed fitting before choosing the plug for an arrangement that eliminates the cable. The speedometer gear plug is a separate 15 mm-outer-diameter, 22 mm-long product; that shared diameter does not establish interchangeability.
