1972 Honda CB350K4 · MPH & KPH Speedometers Buying guide

Compare the two speed scales before buying

The gauges share body dimensions but use different dial units and stated drive specifications. Select by the complete application, including cable, ratio and mounting, rather than dial appearance alone.

Use the exact drive specification

For the MPH dial, the specified ratio is 2240:60; for the KPH dial, it is 1400 rpm at 60 km/h. Check the fitted drive and cable connection. Do not assume that changing the displayed unit alone guarantees the gauge will read correctly.

Make a complete mounting plan

The common body is 85mm across and 55mm thick, with mounting points 57mm apart. Account for the rear projections as well as the face diameter. Both gauges require custom mounting and have LED illumination, so assess bracket location and the lighting connection together.

Buying questions

Do the MPH and KPH units have different body sizes?

Both are specified as 85mm in diameter and 55mm thick, with mounting points 57mm center to center. Verify the entire rear clearance envelope when planning the custom bracket.

Can I retain my existing speedometer cable?

Compare its gauge-end connection and the drive specification before deciding. These are mechanical custom gauges; the existing K4 cable and instrument arrangement are not automatically confirmed as a direct fit.

Is a tachometer included with either speedometer?

Each product is a speedometer. A matching tachometer is referenced separately in the catalog, but it is not included in either of these speedometer purchases.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
