In 1985, the Japanese motorcycle manufacturer released the Honda CB650SC Nighthawk, a standard motorcycle manufactured from 1982 to 1985, as a replacement for the CB650 Custom and without any significant changes.

The 1985 Nighthawk was available in one of two colors, such as Pearl Siren Blue and Candy Wineberry Red. Other unique features of the bike were highlighted by the instrument panel and headlight that was rectangular instead of the round units packed by its earlier predecessors.

Also, the exhaust was a four-into-two system instead of the four-into-four previously used, the front fork had the TRAC anti-dive system, the emblem was located above the axle, the speedometer numbers were increments of 10, and the engine used hydraulic valve-lash adjusters.

In addition, the bike came fitted from the factory with standard features, such as an analog instrument cluster, a chromed dual exhaust system, a dual seat with a passenger grab handle, a side stand, and lightweight cast aluminum wheels.

For suspension, the model packed a 39 mm Showa air-assisted fork on the front and dual Showa adjustable shock absorbers on the rear, while the stopping power was generated by two 275 mm discs squeezed by a couple of two-piston calipers on the front wheel and one 180 mm drum unit on the rear wheel.

In the performance department, the 1985 Honda CB650SC Nighthawk had its muscles flexed by a 626cc four-stroke four-cylinder air/oil-cooled engine fed by four Keihin carburetors, delivered an output power of 50 hp with maximum strength at 8,000 rpm and 49 Nm (36 lb-ft) of torque available at 6,500 rpm.
