Identify your CB450K0 (1966)

This page follows our catalog’s 1966 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.

Plan ignition and carburetor work together

Replacement ignition coil 17-6923 is listed for the 1966 CB450K0. The listing specifies a 12V single-output coil, 5-ohm primary resistance and approximately 80mm mounting-hole centres. Those are replacement-part specifications. Compare the brackets, wire exits and connectors on the fitted ignition before ordering.

Fitment questions

Does the Premium rebuild kit include a replacement float? Its itemised contents list a float needle and seat but no replacement float. Float-with-pin 20-6512 is a separate listing that includes this model year. Check whether the repair needs the float itself as well as the valve parts before choosing the order.

Does carb holder 48-1475 need the clamp sold for that replacement holder? Its description specifies clamp 15-0685 when a band clamp is required. The holder is supplied with a gasket, while the clamp is a separate requirement. Check the existing clamp against the replacement holder instead of choosing a clamp from the bike's year alone.
