1977 Honda CB550K Tachometer & Speedometer Parts

Gauge work on a 1977 Honda CB550K can mean replacing an instrument, renewing a cable or repairing the original housing. Choose that job first. Stock-style speedometers and compact custom tachometers need different comparisons of face markings, drive ratio, connections and mounting space.

1977 Honda CB550K · Tach & Speedo Buying guide

Decide whether to replace a gauge or repair its surroundings

The category combines stock-style instruments, custom gauges, cables and housing repair parts. A cover, glass lens or cushion is not a working instrument, and a custom gauge needs its mounting details checked separately.

Parts to consider

1973-78 Honda CB750 / CB550 Stock Style Speedometer MPH Stock-style MPH speedometerBack-illuminated speedometer with a 0–120 MPH face and listed 60 MPH = 2240 RPM drive ratio. The face design may differ from the original year’s markings; compare the photo.View part Deluxe Mini Custom Tachometer ~ Black Face Plate 7:1 Drive Chrome 7:1 mini tachometerChrome mechanical tachometer with a black face, listed 7:1 ratio and 2.25-inch body.

Measure your cable path and compare both ends; the listing asks buyers to confirm the length.View part

Use face design and ratio as separate checks

The stock-style MPH speedometer lists a 0–120 MPH face and 60 MPH = 2240 RPM ratio, while the KPH instrument lists its own units and ratio. The descriptions warn that face markings may not exactly match every year. Compare the photographed face as well as the existing drive and mount.

Keep custom mounting and repair parts distinct

The 7:1 mini tachometer has a 2.25-inch body and includes a V-plate, with its bracket sold separately. Confirm the actual drive ratio and available mounting space before choosing it. Glass lenses, cushions and cover plates instead repair or dress an existing gauge; they do not replace its mechanism.

Common buying questions

Is a stock-style speedometer face an exact 1977 reproduction?

The description warns that face designs changed between years and may not be an exact match. Compare the product photograph with your original markings when appearance matters, alongside the units, stated ratio and mounting arrangement.

Does the mini tachometer include its mounting bracket?

The 7:1 mini listing includes a mounting V-plate, but specifies a separate bracket. Compare the installed drive ratio and plan the bracket and gauge location before ordering; the compact body alone does not make a complete mounting kit.

Can gauge covers or glass repair a failed instrument mechanism?

Those listings supply housing trim or glass repair pieces, not a replacement mechanism. Identify whether the job concerns the instrument itself, its cable, glass or mounting parts before selecting a cosmetic or housing component for the cluster.

Not sure which part you need?

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