Norton Motorcycle Company

Norton is a British motorcycle marque, originally from Bermingham,  founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade" By 1902, they had begun manufacturing motorcycles with bought-in engines. In 1908, a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and a long history of racing involvement.
Wartime WW2 production of the military Model 16h and Big4 sidevalve motorcycles was Nortons contribution to the war effort, almost 100,000 being manufactured.

When major shareholders started to leave Norton in 1953, the company declined and Associated Motor Cycles bought the shares.^[2] Although motorcycle sales went through a recession in the 1950s, and Norton Motors Ltd was only a small manufacturer, Norton sales flourished. A series of Norton Dominator Twins of 500cc, then 600cc, then 650cc and then the 750cc Norton Atlas kept sales buoyant, especially with sales to the USA.
In 1968, the new 750cc Norton Commando Model appeared, with the engine/gearbox/swingarm unit "isolastically" insulated from the frame with a series of rubber mountings. This kept the vibrations from the rider, giving a smooth comfortable ride. The Commando was a best seller, and voted #1 Motorcycle of the Year a number of times in Britain. 850cc Models appeared for 1973, giving more torque. And for 1975 an electric start arrived in the 850 Mk3.
Political manoeuvrings brought the downfall of Norton and other manufacturers in the 1970s - taxpayer assisted wranglings over amalgamations and sell-offs all but killing the industry.
In late 2008, Stuart Garner, a UK businessman, bought the rights to Norton from some US concerns and relaunched Norton in its Midlands home at Donington Park where it will develop the NRV588 racer, a machine styled after the Norton Commando,^[3] and a new range of Norton motorcycles, with options including 1200 cc Superbike, and 750 cc Supersport variants.<sup>[4]
