1984 Honda CB550SC · Tach & Speedo Buying guide

Make the speedometer choice around the installation

Both gauges list the 1984 CB550SC as a custom application. Their shared body dimensions help with planning, but the chosen unit still needs a compatible drive, suitable mounting and checked illumination connections.

Parts to consider

Vintage-style MPH speedometerCustom mechanical gauge with a 0–130 MPH face, LED illumination and advertised 2240:60 calibration. Approximately 85 mm diameter and 55 mm deep, with 57 mm mounting centers; custom mounting required.View part

Vintage-style KPH speedometerCustom mechanical gauge reading 0–220 km/h, calibrated for 60 km/h at 1400 cable rpm. Approximately 85 mm diameter and 55 mm deep, with 57 mm mounting centers and LED illumination; custom mounting required.View part

Account for more than the face diameter

An 85 mm gauge face is only part of the space check. The product information gives approximately 55 mm depth and 57 mm mounting centers. Compare those dimensions with the proposed bracket position and the space available for the cable and lighting connections before committing to a cockpit change.

Verify the drive before ordering the preferred dial

The MPH listing states 2240:60 calibration; the KPH listing states 60 km/h at 1400 cable rpm. These describe the products, not a verified factory specification for your motorcycle. Compare the chosen gauge with the fitted drive and cable connection, particularly if the wheel or instruments have been changed.

Instrument questions

Does the 1984 model application mean these fit the original mounts?

The listings describe custom mounting, so model application alone does not establish a direct replacement. Compare the gauge’s mounting centers, depth and drive connection with your motorcycle, then plan the bracket and illumination connections for that installation.

Are a speedometer cable and drive included?

These listings describe individual custom speedometers, not a cable-and-drive package. They do not promise a replacement cable or wheel drive. Identify any additional connection parts your installation needs and confirm the supplied gauge contents before ordering.

Which calibration should I check against the fitted speedometer drive?

The MPH listing advertises 2240:60 calibration, while the KPH version specifies 60 km/h at 1400 cable rpm. Check the requirement for the selected gauge against the drive actually fitted; dial style and motorcycle application alone do not establish correct indication.
