1980 Honda CB750K · Camshaft Drive Parts Buying guide

Distinguish A and B components before ordering

The A-chain listing specifies 124 links and the B-chain listing 82 links. The smaller B tensioner and the separately referenced main tensioner are different choices, with a guide and sealing part listed separately.

Use the chain name and reference together

The A and B labels appear on chains with different lengths and Honda references. Record those details when identifying the repair parts. Do not choose a chain simply because another listing is also described as silent, or because both share the 1980 CB750K model application.

Match tensioners and joining hardware independently

The B product is expressly the smaller tensioner, while the genuine Honda main tensioner has a different reference family. A separate rivet-link listing names type 82RH2015 but does not explicitly identify every chain combination. Confirm that compatibility before purchase and use the correct service instructions for the work.

Common questions

Are the A and B chains interchangeable?

They are separate listings: A is 412H x 124 links, while B is 412H x 82 links with different Honda references. Identify the required chain by its position and reference rather than selecting between them by price or appearance.

Which tensioner is described as the smaller one?

The B tensioner listing explicitly identifies it as the smaller tensioner. It gives references including 14530-MG5-670 and 14530-425-000. Compare the removed component and its location before confusing it with the separately listed main tensioner.

Does the separate rivet link prove compatibility with both chains?

Its listing names type 82RH2015 and describes silent-chain use, but does not explicitly confirm both featured 412H chain applications. Resolve the exact chain-and-link match before ordering rather than inferring compatibility from the category or model tag.
