1974 Honda CB550K · Tach & speedo Buying guide

Choose between a complete instrument and its service parts

The featured choices cover a stock-style MPH speedometer, a custom 7:1 tachometer and a meter cushion. Their functions differ: a cushion does not replace a gauge, and a custom instrument needs its mounting and connections checked separately.

Parts to consider

1973-78 Honda CB750 / CB550 Stock Style Speedometer MPH

Stock-style MPH speedometerThe description lists CB550K 1974–78, a 0–120 MPH face and 60 MPH = 2240 RPM drive specification. It cautions that face designs vary by year.View part

Deluxe Mini Custom Tachometer ~ Black Face Plate 7:1 Drive

7:1 custom mechanical tachometerThis 2.25-inch chrome-body tach lists CB550K 1974–78 and a 7:1 drive. LED illumination and a V-plate are included; a mounting bracket is required separately.View part

Honda CB Speedo/Tachometer Meter Cushion ~ Replaces 37235-323-700

Replacement meter cushionReferences 37235-323-700 and lists the CB550K. Two are used per bike, one for each instrument; check the quantity supplied before preparing the order.View part

Take the tachometer ratio from its own description

The selected deluxe tachometer explicitly describes a 7:1 mechanical drive for the CB550 family. Another mini tachometer is advertised with a 4:1 CB750 drive. Those statements do not make the units interchangeable. Match the drive specification and mounting arrangement before choosing a custom tachometer.

Treat gauge repair parts as separate choices

Glass, cushions, internal seals and crimp rings address different parts of an instrument. The ring listing specifically names Nippon Seiki gauges, while the internal seal has its own compatibility wording. Identify the instrument and compare each part independently instead of assuming these separate listings form one universal rebuilding kit.

Instrument replacement and repair questions

Will the stock-style face exactly match a 1974 gauge?

The speedometer description warns that face plates changed slightly from year to year. Its CB550K application supports considering the unit, but exact artwork remains a separate check. Compare the pictured face with the instrument you want to retain.

Does a 7:1 tachometer include all mounting hardware?

The chosen custom tachometer includes a V-plate, while its description requires a mounting bracket separately. Check the proposed location, mechanical cable connection and illumination wiring before treating the gauge purchase as a complete installation package.

Is a meter cushion the same as an internal seal?

No. The cushion description identifies reference 37235-323-700 and says one is used for each instrument. The internal seal is a separate product. Compare their locations and functions with the existing assembly rather than using either name as a substitute for the other.

Not sure which part you need?

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