1978 Honda CB750K · Tach & Speedo Buying guide

Choose the right level of instrument repair

The stock-style gauges, year-specific face plates and small mounting pieces are separate choices. Decide whether you are restoring the existing instruments or changing the gauge arrangement before comparing the products here.

Compare a new gauge with a dial restoration

A face plate purchase supplies the printed faces for your existing instruments. A stock-style speedometer or tachometer is a different product, and those listings warn that the face artwork may vary from the original year’s design. Compare the pictures with the appearance you want to retain before choosing.

Check the assembly around the gauge as well

Cables, cushions, cap nuts and lower cover plates are available separately. Inspect those items while deciding whether to repair or replace the instrument. Decorative chrome covers and lower plates do not include the gauge mechanism, even when a listing photograph shows how the trim looks on an assembled instrument.

Common questions

Should I order face plates or a complete stock-style gauge?

Choose according to the work needed. The 1978 face plate sets replace the visible printed faces and require gauge disassembly. The stock-style gauges are complete instrument listings, with a warning that their face design may not exactly match your original gauge.

Can a gauge cover fix a cable or instrument fault?

A cover replaces or dresses the outside of the instrument; it is not a cable or gauge mechanism. Check the cable and instrument separately when the reading is incorrect, and choose trim only for the piece that is damaged or missing.

Are custom instruments ready for the stock mounts?

Review the individual listing first. Several custom gauges require a separate bracket, and the vintage-style options call for custom mounting. Their units, drive information and lighting also need checking against the instrument arrangement you intend to use.

Not sure which part you need?

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