After the war, Norton takes up civilian production as well as racing. In the 1946 catalogue the "Manx" is offered together with old friends like the Model 18 and the 16H. It is only too obvious the normal roadsters are very dated, and new models must be created. To this aim Bert Hopwood is recruited from Triumph. Hopwood was Edward Turner's assistant, and knows about the shortcomings of the Triumph twin engine. First he redesigns the Norton single engines, then draws up the Norton "Dominator" twin engine, improving on the Triumph one.

In spite of the racing success with the singles, due to a great extent to the new "featherbed" frame, twins soon outnumber them in sales. Production of real Norton singles ends in 1963. The aquisition of Norton by AMC in London in 1953 leads to the drain of all Norton's profits in order to keep AMC afloat. The Norton factory in Birmingham is closed down in 1963, and all production transferred to London.
