1971 Honda CB500K · Tachometer & Speedometer Buying guide
A matching-looking pair can still have incompatible specifications. The featured CB500K tach uses a listed 7:1 mechanical drive, while the speedometers require a separate check of their stated cable-drive calibration and mounting.

The 7:1 tach description names CB500K 1971–73; a visually similar 4:1 product describes CB750 use instead. Keep that distinction clear when comparing the listed model applications. Confirm the installed drive if earlier owners have changed the instrument arrangement.
Each featured custom gauge includes a mounting V-plate, with the bracket required separately. Compare the 2.25-inch diameter and available clearance with the cockpit. LED illumination and the speedometers’ indicator features also need suitable connections; the catalog label does not establish plug-in wiring.
The speedometer listings explicitly say they are not stock-type replacements. The gauges require checks of drive calibration, cable connection, mounting and wiring; a listed model application alone does not establish a complete bolt-on conversion.
The featured MPH version lists a 0–140 MPH face and 60 MPH = 2240 RPM calibration. The KPH version lists 0–220 KPH and 100 KPH = 2330 RPM. Verify the relevant specification before ordering.
No. The featured listings distinguish the included V-plate from the separately required mounting bracket. Plan that bracket alongside gauge clearance and cable routing rather than assuming the gauge package supplies every mounting part.
