The business was founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade".[3] By 1902 the company 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. During the Second World War Norton produced almost 100,000 of the military Model 16 H and Big 4 sidevalve motorcycles.
When major shareholders started to leave Norton in 1953 the company declined and Associated Motor Cycles bought the shares.[4] 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 500 cc, then 600 cc, then 650 cc and then the 750 cc Norton Atlas kept sales buoyant, especially with sales to the United States.
In 1968 the new 750 cc 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 smoother, more-comfortable ride. The Commando was a best seller, and voted #1 Motorcycle of the Year a number of times in Britain. 850 cc models appeared for 1973, giving more torque. For 1975 an electric start arrived in the 850 Mk3. sourced from wikipedia
