In 1933 he also added a couple of 250cc continental Grand Prix wins riding Moto Guzzi machines, and in the same year he broke the run of Norton dominance by winning the 350 class of the Ulster Grand Prix. In 1934 he contracted to race Norton motorcycles and gained his fifth win in the Belgian Grand Prix at Spa. In 1937 he gained the gold star for BSA by lapping the Brooklands circuit at over 107 mph. He did this at a time when most people had wrongly surmised that he had decided to retire.
