HONDA CB650SC Nighthawk 1982-1985

In 1982, the Japanese motorcycle manufacturer released the Honda CB650SC Nighthak, a standard motorcycle part of the CB series in Honda's range that came as a replacement for the CB650 manufactured in 1979.

Starting with 1983, Honda CB650SC Nighthawk came with a DOHC engine that replaced the SOHC unit used from 1979 to 1982 on the CB650 standard model and featured hydraulic valve-lash adjusters and a rubber-mounted system that reduced vibrations.

For suspension, the model packed a 39 mm air-assisted Showa telescopic fork on the front and dual Showa shock absorbers with five-way spring preload adjustability and four-way rebound damping adjustability that offered optimum suspension performance.

As for stopping power, the bike featured two 275 mm discs with two-piston calipers on the front and a 180 mm drum braking unit on the rear that provided strong braking performance.

In addition, the model came with standard features, such as an analog instrument panel, a dual seat with a passenger grab handle, a round headlight, a chromed dual exhaust system, a black-finished steel frame, and lightweight cast aluminum wheels.

As for the power figures, the 1982-1985 Honda CB650SC Nighthawk packed 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.
