The connecting rods would be inherited by the Sportster along with many other design elements and dimensions. This is developed from the earlier 45 W model, but with the revised flat head engine and new 4-speed transmission contained in the same castings as would become the Sportster. The Model K, from which the Sportster evolved, was the first civilian motorcycle produced by Harley-Davidson with hydraulic shock absorbers on both wheels. Buell motorcycles built with variants of the Sportster engine have used a rubber mount system since 1987. Sportsters released in 2004 and later use rubber isolation mounts and tie links to limit engine movement to a single plane, which greatly reduces vibration felt by the rider. They are identified by the 100th anniversary paint schemes and plaques attached to the sheetmetal, speedometer housing, and engine. In 2003 Harley Davidson produced a limited number of 100th anniversary model sportsters. While this system allows the bike to be somewhat lighter with more precise handling, it also transmits engine vibration directly to the rider. The engine was mounted directly to the frame from 1957 through the 2003 model year. Models since 1991 have five speeds 1990 and earlier models had four speeds. Sportster engines retained the K/KH design crankcase design, in which the transmission is contained in the same casting as the engine, and driven by the engine with a triple-row #35 chain primary drive and a multi-plate cable-operated clutch. The company used similar cam followers for decades with minor changes, from 1929 to the 1980s.Ī typical 5-gear, foot-shift transmission on an HD Sportster The cam followers used in Sportster engines, K models, big twin side valve models, and the side-valve W model series, were a slightly shorter version of the followers used in the larger motors, but with the same 0.731-inch (18.6 mm) diameter body and 0.855-inch (21.7 mm) diameter roller follower since 1929. Sportster engines, the 45 cubic inch R, D, G & W Models 1929 side-valve motors, and the 'Big Twin' side-valve motors, which were: the flathead 74.0 cu in (1,213 cc) Models V, VL etc. The original Sportster engine was the Ironhead engine, which was replaced with the Evolution engine in 1986. Sportster motorcycles are powered by a four-stroke, 45° V-twin engine in which both connecting rods, of the 'fork and blade' or 'knife & fork' design, share a common crank pin. Harley-Davidson 45° V-twin, Sportster Evolution engine An all-new model equipped with the Revolution Max engine called the Sportster S was introduced in 2021, the first motorcycle under the Sportster nameplate to receive a new engine since 1986, and the first Sportster to have an engine not derived from the Model K. The original Sportster line was discontinued in Europe in 2020 due to the engine failing to meet the stricter Euro 5 emissions standards. The first Sportster in 1957 had many of the same details of the KH including the frame, fenders, large gas tank and front suspension. These models K, KK, KH, and KHK of 1952 to 1956 had a sidevalve ('flat head') engine, whereas the later XL Sportster models use an overhead valve engine. In 1952, the predecessors to the Sportster, the Model K Sport and Sport Solo motorcycles, were introduced.
