Measure for the arrangement you will retain

A relocated instrument or altered handlebar position can change the cable reach needed. Compare that arrangement with the replacement’s 38.5-inch end-to-end length. Identify the fitted drive and gauge when checking the end connections, which are not dimensioned in this description.

Use the plug measurements for the protective part

The 15mm and 22mm measurements belong to the gear plug, not to cable ends or an instrument drive ratio. Compare them with the actual opening and the protection required. The listing does not establish a conversion kit or a substitute for missing speedometer drive components.

Buying questions

What should I check when keeping the original drive but fitting a custom gauge?

Confirm cable compatibility at both the retained drive and the new instrument, together with the required reach. This description does not give the end dimensions needed to prove the custom pairing. Verify the instrument’s mechanical specification independently of the cable purchase.

Which cable dimensions are provided in the listing?

The black, Japanese-made cable is listed at 38.5 inches end-to-end and replaces Honda 44830-425-870. Exact end-thread and drive-tip dimensions are not given. Confirm both connections when the wheel drive or instrument has been changed.

What if the cable length suits my old layout but the gauge has moved?

Check the reach needed by the intended new arrangement instead of reusing the old layout’s measurement as proof. Compare it with the stated 38.5-inch end-to-end length and confirm both end connections. The model-year application does not establish every custom cable path.
