Identify your CB450K5 (1972)

This page follows our catalog’s 1972 CB450K5 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.

Use the later CB450 carb listing

Carb kit 48-1396 specifically lists the 1972–74 five-speed CB450K and one carburetor per kit. Its current description does not give a carb-body code or full jet list. Confirm those details if you need replacement jets; the stated year range alone cannot tell you which brass parts are supplied.

Fitment questions

Why are two different pad measurements listed for the front set? Set 29-3501 lists the two pads as 52 × 20mm and 52 × 12.8mm. Compare both removed pads rather than matching only one. Its CB450K application is 1972–74; the 1970–71 set is a different listing with different locating features.

Which tail-light lens does gasket 11-2163 belong with? The listing pairs gasket 11-2163 with lens 11-2259 and includes the 1972–74 CB450K application. Confirm the installed lens before ordering, since the motorcycle's year alone cannot identify a replacement lamp fitted during an earlier repair.
