1978 Honda CB550K · Tachometer & Speedometer Buying guide
A speedometer display, a tachometer drive and a lower housing cover are different choices. Compare the present instrument and its mount before selecting a replacement or changing to a smaller custom gauge.
Backlit stock-style MPH speedometerA 0–120MPH speedometer with the stated 60MPH = 2240RPM drive specification. Compare its photographed face with the original; the listing does not promise an exact year-specific face.View part
All-black 7:1 mini tachometerA 2.25-inch mechanical tachometer with LED illumination and a 0–12000RPM dial. The V-plate is included, but its mounting bracket is a separate purchase; confirm the actual drive ratio.View part
Speedometer lower cover plateAn individually sold aftermarket chrome plate for beneath the speedometer housing. Compare the original shape and Honda reference 37236-426-000; this is not a complete speedometer.View part

The MPH listing gives a 0–120 dial and 60MPH = 2240RPM specification. The KPH alternative gives a 0–240 dial and 100KPH = 2330RPM specification. Compare the chosen unit with the fitted drive, and use the photographs to judge the face design rather than expecting an exact year-specific reproduction.
The featured mini tachometer states mechanical 7:1 drive and includes a V-plate, with a bracket required separately. Another mini listing describes 4:1 for stock CB750 applications despite listing this model. Confirm the motorcycle’s actual drive with the store before treating that different-ratio option as appropriate.
Its description includes a mounting V-plate but requires a bracket purchased separately. Check the chosen bracket and the present instrument mounting arrangement before ordering; the plate alone is not described as the complete mounting assembly.
Do not choose between those ratios by appearance or the model list alone. The 4:1 description names stock CB750 applications, while the featured option states 7:1. Confirm the actual drive before selecting a replacement for this motorcycle.
The lower cover-plate descriptions concern pieces fitted beneath the gauge housing. They do not describe a complete speedometer or tachometer. Compare the original plate shape and reference before ordering it for a retained instrument.
