About the Honda CB450SC Nighthawk
Repair parts for the Nighthawk, with the carburetor year split clearly separated.
Honda’s 1982 owner’s manual identifies the CB450SC as the Nighthawk. The SC code distinguishes it from the Hawk and earlier K twin when choosing engine and chassis parts. For a bike returning to regular use, the guide below brings together carburetor, gasket, suspension, brake and clutch options.
Start with the Nighthawk’s model year
Carburetor kits divide into 1982 and 1983–1986 choices. The fork seals and brake parts below list 1982–1986, while some engine and clutch products have different coverage. Compare those individual ranges before combining parts for a service or restoration.

Compare the model years, dimensions and component differences before choosing parts.
1982 carburetors
First Nighthawk kit option
The 1982 SC carb kit also lists the 1982 CB450T Hawk.
Parts checkpoint: Match the fitted carburetor bodies before ordering.
1983–1986 carburetors
Separate later kit
A different rebuild kit lists these Nighthawk years.
Parts checkpoint: Keep the 1982 and later kit choices separate.
Steel clutch plate
Check a 1984 bike separately
The linked steel plate lists 1982–1983 and 1985–1986, leaving 1984 unconfirmed.
Parts checkpoint: Another clutch component’s year range does not fill this gap.
Identify your motorcycle before orderingCB450SC identification checklist
These checks help distinguish a year-specific Nighthawk repair from a superficially similar Honda twin application.
- Identity: CB450SC code, model year, original market and frame and engine markings.
- Carburetors: Body markings, fitted bowls and the 1982 or 1983–1986 kit application.
- Brakes: Front master-cylinder identity and rear drum or hub application.
- Clutch: Required plate type and year; retain any gap in the selected listing.
