NORTON 50

The Model 50 was a Norton touring motorcycle designed by Edgar Franks in 1933, and except for the bore and stroke was almost identical to the Norton Model 18. The single-cylinder engine was 348cc with pushrod operated overhead valves. Halted by World War II, production of the Model 50 single restarted in 1956. Its popularity was partly due to its simplicity and economy, up to 75mpg from an over-engineered but understressed engine capable of 75mph.[citation needed] After 1959 the Model 50 gained the Featherbed frame and improved lighting. Few survive in original condition as many were converted into 'Tritons' with Triumph engines. Production ended in 1963.
