Harley-Davidson Sportster

The Harley-Davidson Sportster is a line of motorcycles produced continuously since 1957 by Harley-Davidson. Sportster models are designated in Harley-Davidson’s product code by beginning with « XL ». In 1952, the predecessors to the Sportster, the Model K Sport and Sport Solo motorcycles, were introduced. These models K, KK, KH, and KHK of 1952 to 1956 had a sidevalve engine, whereas the later XL Sportster models use an overhead valve engine. The first Sportster in 1957 had many of the same features of the KH including the frame, fenders, large gas tank and front suspension.
