Identify your CB450SC (1982)

Our catalog uses CB450SCC for this 1982 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.

Use the early Nighthawk carb kit

Carb kit 48-1398 lists the 1982 CB450SC and 1982 CB450T, while 48-1397 starts its CB450SC coverage at 1983. Use the 1982 application when identifying the kit. Intake holder 33-0017 is a separate item supplied with an O-ring; its listing specifies two holders per motorcycle.

Fitment questions

Does the carb rebuild kit also cover the accelerator pump? The 48-1398 listing does not itemise an accelerator-pump diaphragm. Pump kit 20-9041 separately lists the 1982 CB450SC and includes a diaphragm with rod, bellow rubber and O-rings. Check which components are needed before treating the carb kit as a complete pump repair.

Can a front-or-rear signal replace a lamp with a running-light circuit? Signal 11-2164 is listed for this Nighthawk as an amber single-filament lamp. Its front-or-rear description does not establish a separate running-light function. Compare the installed lamp, connections and required functions before choosing it.
