1981 Honda CB900C Custom Speedometers & Trim

Choose the instrument format and installation scope before ordering for your 1981 CB900C Custom. The mini MPH and KPH speedometers are custom units with separate bracket requirements. Original-style lower plates instead repair existing gauge housings, so keep those two jobs distinct when planning parts.

1981 Honda CB900C Custom · Custom Speedometers & Trim Buying guide

Choose reading units and verify the installation requirements

The selected mini gauges have 2.25-inch chrome bodies, LED illumination and integrated indicators. Their drive ratios and separate mounting brackets must suit the fitted motorcycle; original-housing trim follows a different application.

Check each ratio in its stated units

The MPH gauge specifies 60mph at 2240rpm and the KPH gauge 100km/h at 2330rpm. Compare the fitted drive system with the selected instrument before purchase. A shared appearance or broad CB application does not establish correct reading on a modified drive arrangement.

Plan the custom mounts, inputs and indicators

The deluxe custom speedometers include a V-shaped mounting plate, but their separate mounting bracket is an additional purchase. Match the cable fitting and stated MPH or KPH calibration, then plan wiring for the four indicator lamps. The original CB900C tachometer is also cable-driven; a matching 4:1 custom tachometer still needs its own drive-ratio and mounting confirmation.

Buying questions

Does the V-shaped plate make these gauges bolt-on replacements?

No. The product includes the plate but specifies a separate mounting bracket. Check the fitted cable end, available mounting space and wiring for illumination and indicators before choosing a custom gauge for the original cockpit.

Can I choose MPH or KPH purely by the face marking?

Match the stated mechanical calibration as well: the deluxe MPH gauge specifies 2,240 rpm at 60 mph, and the KPH version specifies 2,330 rpm at 100 km/h. Compare the actual drive and cable connection, especially if the wheel or gauge system has been changed.

Is a matching 4:1 tachometer automatically correct for the Custom?

The CB900C has a mechanical tachometer cable, but the matching custom tach’s 4:1 listing does not by itself verify the original drive ratio. Confirm that ratio, cable engagement and mounting before treating a coordinated face style as a compatible pair.
