who can guess.
The Honda CB77, or Super Hawk, was a 305 cc (18.6 cu in) vertical twin motorcycle produced from 1961 until 1967. It is remembered today as Honda's first sportbike. It is a landmark model in Honda's advances in Western motorcycle markets of the 1960s, for its speed and power as well as its reliability, and is regarded as one of the bikes that set the paradigm for modern motorcycles.
Christopher nailed it. I actually had one for about 2 months in the shop.. never had oil in it so never got to take it out for a spin :(
