1963 Norton 750cc Atlas
Frame no. 104725 20
Engine no. 104725 20

The first Atlas was announced in 1962 as the 750SS but by the time it appeared later that year the 'SS' had gone to be replaced with 'Atlas.' Essentially it was a development of the Featherbed-framed, Bert Hopwood designed 600/650 Dominator, the parallel twin enlarged out to 745cc. The thought behind the 750-moniker was its potential appeal in the American market on which Norton initially focused. It is rumored that Joe Berliner, America's Norton importer, when at the Birmingham factory was heard to utter, 'Give me a bigger engine, a nice 45 cubic inches.'

The engine had lower compression than the Dominator (at 7.6 to 1) and was fitted with a single Amal 376 Monobloc carburetor and a Lucas comp. magneto giving 55 horsepower at 6,500 rpm. The specification, however, produced excessive vibration at high revs, so the compression ratio was reduced. The Atlas, logically, shared many cycle parts with the last of the well-loved Dominators including Norton's 4-speed gearbox with a heavier-duty clutch.

This one is thus a rare piece. Beautifully and accurately restored to its original Cherry Red North America market street specification but with a number of 'hidden' upgrades to enhance the riding experience in today's world such as a dynamically balanced crankshaft to smooth out the aforementioned tendency to 'vibrate one's fillings out.' A single Amal Concentric carburetor to replace the Monobloc, electronic ignition to rid the bike of its the archaic magneto together with 12-volt electrics were also added. It demands serious consideration for any collector with Norton in his or her DNA already, or someone who wishes to obtain the same.
