The CB700SC Nighthawk 700S is a carburated, air-cooled, in-line four-cylinder motorcycle marketed by Honda solely in the United States for model years 1984-1986 — with a standard or neutral, almost upright riding position, 6-speed transmission, hydraulic valve lifters, shaft drive, front bikini mini-fairing, gear indicator and 16" front wheel. At its introduction, the motorcycle carried a list price of $3,398.
The Nighthawk 700S bodywork (1984–1985) was mostly black in color—with either red or blue accent panels. In 1986, the 700SC's paint was mostly navy blue (with white accent decals with red pinstripes) or black (with red accent decals and tri-color pinstripes). Valve cover and clutch covers were painted black as well as the wheels. The engine was painted black with polished edges on the cylinder head fins. Other components were also enameled in black including the lower fork legs, handlebars, and rear grab rails.
Design and features
The four-cylinder engine featured double overhead cams, with hydraulic lifters which eliminated valve adjustments. The exhaust was a four-into-two finished in black chrome. The engine layout was the same as the 650 Nighthawk's, but of a different design sharing no parts. The bike also featured shaft drive, electronic ignition, a digital gear indicator, an automatic cam chain adjuster, a spin-on automobile-style oil filter, and Honda’s second-generation TRAC (Torque Reactive Anti-dive Control) front end control system. Tire size in both front and rear was 16 inches. Brakes were double disc in front, drum in rear.
The actual engine size of the CB700SC was 696cc, which by design was below the 700cc limit of a steep tariff imposed in 1983 by the United States International Trade Commission. In Europe and Canada, Honda marketed the CB750SC, a virtually identical bike with a slightly larger engine capacity.
