The Dominator is a twin cylinder motorcycle developed by Norton to compete against the Triumph Speed Twin. The original Dominator was designed in 1947 and 1948 by Bert Hopwood, who had been on the Speed Twin design team at Triumph.[1] Available for sale from mid 1949, this design set the pattern for Norton twins for the next 30 years.[2]
