1968 Honda CB350K0 Custom Instruments

The current instrument choices for the 1968 CB350K0 are custom mechanical speedometers in MPH or KPH. Both use an 85mm body and require custom mounting, so plan the gauge location, cable connection and illumination wiring before replacing the existing speedometer.

1968 Honda CB350K0 · Custom Instruments Buying guide

Plan a custom speedometer around the original instrument functions

Honda’s original instruments use separate speedometer and tachometer cables. These available gauges measure road speed; choosing one also means planning how the retained tachometer, warning indicators and mounting hardware will fit the finished arrangement.

Parts to consider

Custom Vintage Style Speedometer MPH Custom MPH speedometer0–130 MPH mechanical gauge, 85mm diameter, with a stated 2240:60 ratio and LED illumination.View part Custom Vintage Style Speedometer KPH Custom KPH speedometer0–220 KPH mechanical gauge, 85mm diameter, calibrated at 1400 rpm for 60 km/h.View part

Separate the face units from drive compatibility

The MPH gauge is specified at 2240:60; the KPH gauge is specified at 1400 rpm for 60 km/h. These are the replacement gauge calibrations, not verified original K0 drive specifications. Confirm the existing drive and cable combination before ordering either version.

Make room for the whole instrument arrangement

Both gauge bodies are specified at 55mm thick, with a separate 25mm back-mount dimension and 57mm mounting-point centers. Compare the rear connections and bracket clearance as well as the visible 85mm face. Neither product is presented as a stock K0 instrument assembly.

Ordering questions

Are these direct replacements for the original instrument assembly?

Both require custom mounting. Check the 85mm body, 57mm mounting centers and rear clearance, then verify the cable and drive calibration. Their inclusion in the model range does not establish a bolt-in fit to the original instrument mount.

Do these speedometers replace the tachometer too?

They are road-speed instruments. The original Honda setup has separate speedometer and tachometer cables, and these two products do not supply a tachometer. Plan the retained tachometer and indicator positions as part of the custom layout.

Does LED illumination mean the speed signal is electronic?

No. Both speedometers use a mechanical drive; LED refers to their lighting. Confirm the cable connection and calibration separately from the illumination wiring. An electronic speed sensor is not a substitute for the required mechanical input.

Not sure which part you need?

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