1965 Honda CB450K · Tach & Speedo Buying guide

Plan the instrument installation before choosing a dial

The two listed gauges measure road speed. Neither is a tachometer or a confirmed direct replacement for the original CB450K instrument. Their shared dimensions help with layout, while the drive specification needs its own check.

Parts to consider

Choose units for the roads you use

An MPH face suits speed limits shown in miles per hour; a KPH face suits kilometres per hour. That choice determines how you read the dial, but it does not establish compatibility with the wheel drive or the cable fitted to your motorcycle.

Allow room behind the gauge

The listings give an 85mm diameter, 55mm body thickness and mounting points 57mm apart. Check those dimensions against the bracket you intend to use. Leave room for the cable connection and lighting leads rather than measuring only the visible face.

Buying questions

Will either speedometer fit the original CB450K mount?

These listings specify custom mounting. Measure your bracket, gauge opening and cable connection before ordering. A model-year listing does not establish that either unit fits the original instrument housing or bracket.

Does LED illumination mean these gauges use an electronic speed signal?

No. Both listings identify a mechanical drive and LED illumination. The speed input and the lamp wiring are separate requirements; confirm the mechanical cable connection as well as the lighting connection for your installation.

Is there a tachometer in this category for my 1965 bike?

The products shown here are MPH and KPH speedometers. A linked matching tachometer still needs separate checks against the drive ratio, cable and mounting on your 1965 CB450K. Matching styling does not establish instrument compatibility.

Not sure which part you need?

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