1971 Honda CB450K Mechanical MPH or KPH Gauges

A custom speedometer for your 1971 CB450K needs a mechanical match before its face units decide the choice. Compare the installed drive with the exact MPH or KPH specification. Then check cable attachment and the space needed for the gauge and custom bracket.

1971 Honda CB450K · Tachometer & Speedometer Buying guide

Keep the mechanical specification with each instrument

The MPH option states 2240:60; the KPH option states 60 km/h = 1400 rpm. Both list 85mm diameter, 55mm thickness, 57mm mounting centres and LED illumination. Neither confirms direct original-bracket compatibility.

An attached cable does not settle drive calibration

Cable-end fit establishes one connection, while the mechanical specification establishes another requirement for the instrument. Check both with the drive installed on the motorcycle. Use the exact MPH or KPH listing selected rather than treating similar housings or dial styling as proof that the two specifications interchange.

Include body and connections in the space check

The stated 55mm thickness and 57mm mounting-centre spacing help compare the intended layout. Allow for the rear cable and lighting connections too, rather than assessing only the 85mm circular outline. Confirm any bracket or cable needed separately; a complete custom installation package is not described.

Buying questions

How should I compare the gauges when changing the display units?

Compare each product’s stated mechanical requirement with the fitted drive instead of selecting only by MPH or KPH markings. Verify the cable interface and mount as separate details. The descriptions provide distinct specifications, without confirming that the existing arrangement suits either choice automatically.

Does LED lighting imply an electronic speed sensor is required?

Both products are described as mechanically driven speedometers. LED illumination refers to their lighting. Check the mechanical input separately from the lamp connection, and confirm any missing electrical details before assuming a sensor, voltage specification or complete wiring kit is supplied.

What must be checked before reusing a gauge housing or bracket?

Compare the actual enclosure and mount with the listed 85mm diameter, 55mm thickness and 57mm mounting centres. Check room for the rear connections as well. The custom-mounting requirement does not establish a direct fit inside the motorcycle’s original instrument housing.
