Identify your CB450K0 (1965)

This page follows our catalog’s 1965 CB450K0 application. Compare the complete frame and engine markings with documentation for the motorcycle’s original market; registration year or paint colour alone is not enough. A verified frame-and-engine serial range is not provided here.

Use our Honda CB model guide for help locating identifiers.

Check the K0 application first

Our Premium Carburetor Rebuild Kit lists a #125 main jet, #40 pilot jet and D8 needle. These are the replacement kit's contents, not a verified factory specification for every 1965 K0. Identify the carburetors and compare the required jets before fitting the supplied brass parts.

Fitment questions

Can I use gasket set 18-0098 when its range starts at 1965? The same listing restricts CB450K use to five-speed models. Its broad 1965–74 range is not sufficient evidence for this K0 application. Resolve the engine version and obtain a confirmed gasket application before ordering.

Will replacement coil 17-6923 use the original mounting orientation? Not necessarily. The replacement listing specifies approximately 80mm mounting-hole centres and warns that its wires exit differently from a beige Honda coil. Compare the bracket and lead route before installation; a matching application does not mean the old orientation will work.
