The Honda CB77, also known as the Superhawk, was a 305cc straight-twin motorcycle manufactured from 1961 until 1967 and remembered as the first sports bike in Honda's range.
In the 1960s, the bike was a landmark for the Western motorcycle markets and was noted for its speed and power as well as reliability, but also regarded as one of the bikes that set the standards for modern motorcycles.
The CB77 model had packed a 305 cc engine, which was relatively large compared to other bikes at that time, and the performance capabilities to rival much larger motorcycles from other countries. The bike quickly built a reputation for reliability and featured an electric starter, which at the time was considered a luxury.
Also, the bike was built with the experience gained from the Grand Prix racing program and was much different from previous models with its steel-tube frame instead of the pressed units of earlier models and its telescopic front fork.
The tubular steel frame housed a telescopic fork on the front and dual shock absorbers on the rear that provided optimum suspension performance, while the stopping power was handled by a drum braking unit both front and rear.
As for the performance figures, the 1963 Honda CB77 Superhawk took its muscles from a 305cc four-stroke twin-cylinder air-cooled engine fitted with two Keihin carburetors that helped deliver an output power of 28 hp at 7,500 rpm and 23 Nm (17 lb-ft) of torque at 6,000 rpm.
