1963 - 1969 Norton ATLAS 750[edit]

The 1963 Norton Atlas evolved from the Norton Dominator line, which had grown since its inception in 1949 from 500 cc to 600 cc then again to 650 cc with the fire-breathing twin-carb Dominator 650 SS. The Norton Atlas was the next logical step. The engine had lower compression than the Dominator (at 7.6:1) and was fitted with a single 376 Amal monobloc carburetor giving 55 hp (41 kW) at 6500 rpm.
