1978 Honda CB400TI Hawk I · Custom Speedometers Buying guide
The featured MPH and KPH instruments are custom fit-check choices. The original Hawk I used a speedometer only, so this selection does not treat a tachometer as a stock replacement.
85 mm custom MPH speedometerMechanical 0–130 MPH gauge with a 2240:60 drive ratio and 57 mm mounting centers. The 85 mm case requires custom mounting and a compatibility check.View part
Mini custom KPH speedometer2.25-inch white-face gauge, 0–220 KPH, calibrated at 100 KPH = 2330 RPM. A V-plate is included; a mounting bracket is required separately.View part
The vintage-style MPH speedometer has an 85 mm case, 55 mm body thickness and 57 mm mounting centers. The mini KPH unit is 2.25 inches in diameter. Check clearance behind the instrument for its drive connection and wiring as well as space around the dial.
The mini includes a V-plate but requires a separate mounting bracket. Its lighting and indicator features need an appropriate wiring plan, while the mechanical drive needs the correct calibration and connection. A gauge’s model-category placement does not establish bolt-on or plug-in compatibility.
The vintage-style MPH gauge is specified at 2240:60. The mini KPH gauge is specified at 100 KPH = 2330 RPM. Compare the selected unit with the actual wheel-drive arrangement before ordering, particularly after a front-end change.
It includes a mounting V-plate, but a separate bracket is required. Check how that bracket will attach at the intended instrument position and confirm the remaining hardware needed for your custom installation.
The Hawk I originally had a speedometer only. Adding a tachometer is a separate conversion that requires a supported drive arrangement and calibration; the presence of a tachometer in a model-filtered grid does not establish that conversion.
