1978 Honda CB550K · Tach & Speedo Buying guide
Complete instruments, glass and crimp rings, cushions and cables are separate purchases. Check the fitted gauge and its drive first, then choose parts for the specific repair rather than the whole instrument cluster.
Stock-style MPH speedometerA backlit 0–120MPH instrument with a stated 60MPH = 2240RPM drive specification. The description warns that the face design may not exactly match every year.View part
Tachometer drive cableA black replacement cable with a stated 29-inch length and CB550K 1977–78 application. Compare its ends and the actual routing before choosing it for changed instruments or bars.View part

The stock-style MPH speedometer gives a 60MPH = 2240RPM drive specification and cautions that its face design can differ by year. The mini tachometer instead specifies a mechanical 7:1 drive. Compare the actual drive and mounting arrangement before choosing an instrument simply because its finish suits the motorcycle.
The crimp rings are specifically described for Nippon Seiki gauges, while replacement glass is a separate product. Identify the housing maker and compare the listed dimensions before planning a gauge repair. Cable replacement is another purchase; compare the installed path and fittings rather than treating glass or rings as a complete instrument.
The description says face designs changed slightly between years and may not match every year exactly. Compare the product photograph with the retained gauge, along with its stated units and drive specification, before ordering.
The crimp-ring listing specifies Nippon Seiki gauges and gives inner and outer diameters. Identify the actual maker and compare the housing before ordering; a Honda model application does not extend that maker-specific requirement to every replacement gauge.
The speedometer and tachometer cables are separate listings. Compare the required cable ends, stated length and actual routing before adding one; an instrument, glass set or crimp-ring set does not describe a complete cable package.
