This collection covers listed repair and service parts for the 1985 Honda CB450SC Nighthawk, catalogued here as CB450SCF. 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 (1985)

Our catalog uses CB450SCF for this 1985 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.

Compare brake and fork components

The 1985 CB450SC is explicitly listed for fork seal set 27-1019, measuring 33 × 46 × 11mm, and front pad set 29-3542. The 1986 front-pad application is a separate listing. Compare the fitted fork seals and pad shape before ordering after any front-end changes; these are replacement-part dimensions and applications.

Fitment questions

Does the 89mm note on pump kit 20-9040 describe my Nighthawk pump? The listing attaches that measurement condition specifically to its CB650 applications. It separately lists the 1985 CB450SC. Do not turn the CB650 note into a factory specification for your Nighthawk; compare the actual diaphragm, rod and fitted pump before ordering.

Can I carry the 1982 carb kit forward to the 1985 bike? The catalog separates kit 48-1398 for 1982 from kit 48-1397 for 1983–86 CB450SC. Use the latter stated application for a 1985 bike, then confirm the fitted carburetors have not been changed. Shared intake-holder coverage does not make the two rebuild kits equivalent.
