1973 Honda CB450K Cable Reach & Drive Interfaces

Choose the speedometer cable for your 1973 CB450K from the fitted drive, retained instrument and required reach. The black replacement gives a Honda reference and end-to-end measurement. A separate protective plug has its own dimensions, which do not describe the cable’s attachment or calibration.

1973 Honda CB450K · Cables Buying guide

Use overall cable length with the actual end interfaces

The Japanese-made cable replaces Honda 44830-425-870 and measures 38.5 inches end-to-end. Exact end threads and drive-tip dimensions are unstated. The gear plug is described for drive cleanliness, with 15mm outer diameter and 22mm length.

Compare measurements on the stated overall basis

The cable figure is expressly end-to-end, so compare an equivalent overall requirement rather than an assumed casing-only length. A changed instrument position can alter the required reach. Verify both end interfaces alongside that comparison, since overall length and a Honda reference do not give every connection dimension.

Check any changed drive before choosing connections

An altered front end may use a drive whose interface needs identifying directly. Match that connection and the instrument input before selecting the cable, and verify a custom gauge’s mechanical requirement separately. The protective plug’s outer dimensions cannot supply the missing thread or drive-tip information for that cable choice.

Buying questions

Which length should I compare if my removed cable’s casing was measured alone?

The listing gives 38.5 inches end-to-end, without a separate casing-only figure. Establish the equivalent overall measurement needed for your comparison or obtain the missing casing information. Keep the measurement bases distinct before deciding whether the replacement has the required reach.

What should I record when retaining a replacement front wheel or drive?

Identify the drive interface and the cable-end fit it needs, together with the retained gauge connection. Exact threads and drive-tip measurements are not provided here. Compare the required reach and mechanical input as separate details before completing the cable order.

How do I choose the plug when the drive opening has changed?

Compare the actual opening and protection requirement with the listed 15mm outer diameter and 22mm length. The stated role is keeping the original drive gear clean. Confirm suitability for the changed arrangement without inferring another drive’s sealing or cable dimensions.
