1981 Honda CB650C Custom Instruments & Drive Cables

Instrument repair on the 1981 CB650C may be a cable job, a rubber-mount repair or a custom gauge project. Identify which equipment remains fitted before ordering. The speedometer cable has a specific 1981 Custom reference, while the tachometer drive and cushions need their own checks.

1981 Honda CB650C Custom · Instruments & Drive Cables Buying guide

Choose the cable and support for the instrument fitted

The speedometer cable replaces 44830-MA5-670 and the tachometer cable 37260-426-000. The meter cushion is another separate component, with one specified at each of the two original-type gauges.

One cushion is specified for each gauge, two on the CB650C.View part

Preserve the 1981 speedometer application

The selected speedometer cable explicitly lists the 1981 CB650C Custom. Compare its ends and routing with the fitted drive and instrument. Do not select an earlier Custom cable simply because the outer casing and overall purpose appear similar.

Treat a custom instrument as a separate fit check

The original-type cushions and cables should not be presumed compatible with every replacement gauge. Compare the drive, connection and mounting requirements of the actual instrument. A listed custom speedometer still needs its own mounting and electrical plan before purchase.

Instruments & Drive Cables questions

Why can the speedometer still jump or make noise after a cable change?

Inspect the instrument and wheel-drive unit for wear or binding as well as the cable. Check for sharp bends or tension and fully seated ends; follow the cable maker’s lubrication instructions. A replacement cable cannot repair a worn or binding drive or gauge.

Can new gauge trim cure movement caused by the rubber mounts?

A hardened, split or compressed meter cushion can let the instrument move even when the chrome cover looks sound. Inspect the brackets, sleeves, washers and fasteners too. Cushion 73-0096 is sold individually; the original speedometer and tachometer each use one.

Can a tachometer ratio be selected from CB750 guidance?

Do not carry that assumption across models. Confirm the required drive ratio for the fitted CB650C equipment and the selected gauge before buying a custom tachometer.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
