1963 is the last year of Norton singles, and only the twins stay in production. AJS models with Norton badges (ES2Mk2) are of no concern here. As Joe Berliner, the US importer and best customer of Norton, is always clamouring for more bikes, mongrels using AMC and Norton parts are being produced for him until AMC goes finally under.

AMC is liquidated in 1966, and Manganeze Bronce under Dennis Poore as chairman buys Norton. Poore wants a completely new model. He wants to replace the old "Dominator" engine by now stretched to 745cc in the "Atlas". To isolate the rider from engine vibrations, a new principle, the "Isolastics", are invented, rubber mounting engine, gearbox and rear swinging arm in the chassis as a seperate unit. As the planned new engine proves to be an engineering desaster, the Atlas engine is pressed into service yet again, and the resulting new bike called the "Commando".
