James Lansdowne Norton founded the company that bears his name in 1898, first making bicycle parts and then motorcycles. The first Norton motorcycle was the 1902 Energette, powered by a 143cc Clement engine. In 1907, Rem Fowler rode a 5-horsepower Peugeot-powered Norton in the first Isle of Man TT. Norton started making his own engines in 1908, a side-valve single, and by 1909, Norton motorcycles could be purchased in Harrod’s department store. Norton became known as one of the best in the business and their racing success continued.

Norton won 78 out of 92 Grand Prix races between 1930 and 1937, and seven of the nine Isle of Man TT races between 1931 and 1939. Like other manufacturers during WWII, Norton withdrew from racing and focused on military production. Between 1937 and 1945, Norton manufactured nearly 100,000 motorcycles.
