The 1st Norton Model 77 Dominator was a 500 cc all iron
The 2nd, and more well known Norton Model 77 Dominator was a 600 cc vertical twin motorcycle manufactured by the Norton Motorcycle Company from 1956 to 1958. It was based on the Model 7 that it superseded, and was primarily intended for sidecar use.[2] Norton modified the featherbed frame of the 88 and 99 models in 1957 to be suitable for sidecar use making the Model 77 superfluous and the model was dropped in 1958.[3][4]
Technical details
600cc Engine
Based on the 1949 Bert Hopwood designed 500 cc twin engine, the engine had been enlarged to 600 cc by enlarging the 500's bore and stroke of 66 mm (2.6 in) x 72.6 mm (2.86 in) to 68 mm (2.7 in) x 82 mm (3.2 in). The same engine was used in the 99 Dominator.[3][4][5]
Cycle parts
The 77 used the same cycle parts as the previous Model 7,[6] which was also used on the ES2. The single downtube frame was made of tubes and brazed lugs. Front forks were Norton's roadholders.[3][4][5]
