The Norton 650SS is a 650 cc (40 cu in) vertical twin motorcycle made by Norton Motorcycle Company from 1962 to 1967. The 650SS was based on the Norton Manxman.
The machine was capable of 110–115 mph (177–185 km/h).[1][2] SS stood for Sports Special. Norton discontinued its 600 cc models to concentrate on production of the 650SS, which quickly gained a reputation as the "best of the Dommies"[attribution needed].[3]
