1951 Norton Dominator 500cc Solo Motorcycle

In 1949, Norton broke with years of tradition and introduced their first twin cylinder engine machine, the Model 7. This model was the Norton factory's first twin cylinder machine of the modern era and made its debut at the 1948 Earls Court Show. Early versions used the plunger rear end frame with Roadholder forks, but in late 1952 the change was made to the swinging arm frame. The engine had a single carburettor and developed about 29 b.h.p., reasonable for its time.
