The history of the motorcycle begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel. Despite some early landmarks in its development, the motorcycle lacks a rigid pedigree that can be traced back to a single idea or machine. Instead, the idea seems to have occurred to numerous engineers and inventors around Europe at around the same time.
Osborn Engineering Company was a British manufacturer of motorcycles, which sold its machines under the OEC brand name.
The Harley-Davidson KR or KR750 was a 45.125 cu in (739.47 cc) displacement V-twin engine racing motorcycle made by Harley-Davidson from 1953 through 1969 for flat track racing. It was also used in road racing in the KRTT faired version. When the KR was first introduced, it dominated motorcycle racing in the United States. In 1970 it was replaced by the long-lived and US race-winning Harley-Davidson XR-750.
