The Dunstall Norton was a Norton motorcycle made by Paul Dunstall, a specialist tuner of the 1960s and early 1970s twins originally using some parts from Norton's Domiracer project when the Birmingham factory was closed in 1963. In 1966 Dunstall Motorcycles became a motorcycle manufacturer in its own right so that Dunstalls could compete in production races, and set a number of world records before sales of the Dunstall Nortons declined in the 1970s consistent with the demise of the British motor cycle industry and a corresponding rise in Japanese imports.
