This collection covers listed repair and service parts for the 1984 Honda CB450SC Nighthawk, catalogued here as CB450SCE. Match the full model-year application and installed component before ordering. The CB450 name also appears on other Honda models, so displacement alone does not establish compatibility.

Identify your CB450SC (1984)

Our catalog uses CB450SCE for this 1984 CB450SC Nighthawk application. Compare the complete frame and engine identifiers with Honda documentation for the motorcycle’s original market. Registration year, paint colour and the tank badge alone do not confirm the application.

Use our Honda CB model guide for help locating identifiers.

Check the exact 1984 listing

The 1984 Nighthawk needs exact-year checking where a listing skips a year. Oil filter 15-0007 lists 1982–83 and 1985–86 CB450SC, so that description does not establish its 1984 application. By contrast, the linked fork seals, rear shoes and rear-wheel seal explicitly include 1984. An omitted year needs confirmation, not an assumption of interchangeability.

Fitment questions

Can I order float 20-6507 using a general CB450SC description? Its stated CB450SC range also skips 1984. Carb kit 48-1397 lists 1983–86, but that separate kit application does not establish the float application. Identify the installed carburetor and obtain confirmation for the float before adding it to the order.

Does a front-or-rear signal necessarily preserve every lighting function? Lamp 11-2164 lists 1982–86 CB450SC and is single-filament. Check whether the fitted lamp uses a separate running-light function as well as signalling; a broad front-or-rear description does not promise both functions.
