1978 Honda CB550K · Mounts, Rubbers & Hardware Buying guide

Identify the retained gauge before selecting repair pieces

A cushion belongs to the instrument support, while glass and crimp rings serve the gauge housing. Match the maker, shape and dimensions of the part being renewed rather than combining them by model name alone.

Parts to consider

Honda CB Speedo/Tachometer Meter Cushion ~ Replaces 37235-323-700 Speedometer or tachometer cushionA meter cushion referencing 37235-323-700. The listing says one is used for each instrument and tells buyers to order the quantity required; do not assume a two-piece pack.View part Honda CB750 / CB550 / CB500 Speedometer & Tachometer Replacement Glass Lens Set/2 Replacement gauge glass setTwo replacement glass lenses with a stated 92mm size and slight curvature.

Separate usage counts from supplied quantities

The cushion listing says two are used on the motorcycle, one at the speedometer and one at the tachometer, and asks buyers to order the required quantity. By contrast, the glass and crimp-ring descriptions explicitly state sets of two. Use each listing’s wording when planning the purchase.

Do not transfer a maker-specific requirement

The crimp rings specify Nippon Seiki gauges. The internal rubber-seal listing separately refers to ND gauges while also naming CB550 applications, so confirm the actual maker and seal profile with the store before choosing that seal. Chrome outer covers are another purchase and do not include instruments.

Common buying questions

Are two meter cushions supplied as one pack?

The description states the motorcycle uses two cushions and asks buyers to order the required quantity. It does not identify a two-piece sales pack. Count which fitted cushions you intend to replace before ordering.

Are the glass and crimp rings supplied together?

They are separate listings, each explicitly described as a set of two. The ring set adds a Nippon Seiki requirement and its own dimensions; compare the retained gauge before adding either product to the repair order.

Do the chrome covers include the gauges shown?

No. The chrome-cover description explicitly says the speedometer and tachometer are not included in its photograph. Compare the stated cover dimensions and trip-reset cutout with the gauges you plan to retain.

Not sure which part you need?

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