About the Honda CB550SC Nighthawk

A DOHC, shaft-drive Nighthawk with separate master-cylinder, slave-cylinder and fork-service choices.

Honda Motorcycle Logo

The CB550SC Nighthawk uses a DOHC four-cylinder engine with hydraulic valve-lash adjusters, a hydraulic clutch and shaft drive. Honda’s 1984 Canadian brochure includes the 550 in its Nighthawk range. These features make the SC a distinct service proposition from the earlier CB550F and K, despite the shared CB550 name.

Separate clutch controls from clutch actuation

The clutch master cylinder is at the handlebar; the slave cylinder is at the engine. Their repair kits service different assemblies. Fork service is a separate choice: the selected two-seal set lists 1983–1984 and measures 37 × 50 × 11 mm. For an earlier Four or Super Sport, return to the CB550 family guide.

Know your CB550SC before choosing partsCB550SC repair checkpoints

Use these assembly-specific notes to plan your repair.

Hydraulic clutch | 1983 examples

Master or slave cylinder

The master kit services the handlebar unit; the slave kit services the engine-side unit.

Parts checkpoint: Locate the assembly requiring repair before choosing the kit.

Engine service | 1983 examples

Carburetor and gasket kits

Both selected engine-related listings specify 1983 for CB550SC.

Parts checkpoint: Match the supplied pieces to the work being undertaken.

Forks | 1983–1984 example

37 × 50 × 11 mm oil seals

The selected set supplies two seals for this stated SC application.

Parts checkpoint: Tube condition and the complete fitted-fork specification still matter.

Honda CB550SC parts questions

Does the CB550SC Nighthawk use the same engine parts as a CB550K?
The SC is a later DOHC Nighthawk with hydraulic valve-lash adjusters, shaft drive and a hydraulic clutch. The earlier K application cannot establish SC fitment. Use parts that explicitly list the SC model and year.
Which CB550SC clutch repair kit do I need?
The master-cylinder kit services the handlebar unit. The separate pushrod and bushing are master-cylinder parts sold individually; order the quantity required. The slave cylinder is at the engine and requires its own supported service parts. The featured in-stock master-cylinder items list CB550SC 1983.
What size are the featured CB550SC fork seals?
The selected oil-seal set specifies 37 × 50 × 11 mm and contains two seals. Its CB550SC application is 1983–1984. Match the fitted forks as well as the model year.
Do the featured engine gasket and carb kits fit a 1984 CB550SC?
Their stated CB550SC application is 1983. The 1983–1984 range on the fork-seal product does not establish a wider engine-kit application. Provide the complete model and market if you need help with an unlisted year.
