History[edit | edit source]

Although the Honda Nighthawk CB750SC Motorcycle had been introduced in 1982, the 700 cc Nighthawk debuted two years later. In fact, the 1984 750 and 700 were almost identical except for the engine size. In Canada, for instance, the dealers opted for the 750 rather than the 700 because Canada did not have the tariffs that the U.S. imposed on motorcycles over 700 cc.

While its ancestor, the 650 Nighthawk, had a standard Motorcycle style, the 700 had angular lines capped by a small "bikini" fairing and a smaller (16 inch) front wheel which was the rage for sportbikes. The bike came only in black with either red or blue accent panels.

The engine was a larger version of the 650 Nighthawk's double-overhead cam, four cylinder with hydraulic lifters which virtually eliminated valve adjustments. The exhaust was a four-into-two finished in black chrome. The engine was enameled mostly in black with chrome trim. Other components normally chromed were also enameled in black including the lower fork legs, handlebars, and rear grab rails.

Since full-tilt sportbikes of the era were gravitating toward a more radical look with full fairings and crouched seating positions, the Nighthawk filled the gap between sport and standard motorcycles. Though a good compromise and a capable performer, the 700 Nighthawk was phased out after the 1986 model.


Engine[edit | edit source]

The engine was a oil & air cooled in-line four, four-stroke. A 67.9mm bore x 49.4mm stroke result in a displacement of just 696.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).

Drive[edit | edit source]

The bike has a 6-speed transmission. Power was moderated via the hydraulic clutch.

Chassis[edit | edit source]

Stopping was achieved via double disc in the front and a expanding brake (drum brake) in the rear. The CB700SC Nighthawk S was fitted with a 4.2 Gallon (15.89 Liters) fuel tank. The bike weighed just 468.92 pounds (212.7 Kg).
