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 flat head engine, whereas the later XL Sportster models use an overhead valve engine. The first Sportster in 1957 had many of the same details of the KH including the frame, fenders, large gas tank and front suspension.WL 739 cc engine Harley-Davidson 45° V-twin, Sportster Evolution engine 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. The original Sportster engine was the Ironhead engine, which was replaced with the Evolution engine in 1986.

The company used similar cam followers for decades with minor changes, from the 1929 to the Eighties. A typical 5-gear, foot-shift transmission on an HD Sportster 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. Models since 1991 have five speeds; 1990 and earlier models had four speeds. The engine was mounted directly to the frame from 1957 through the 2003 model year. While this system allows the bike to be somewhat lighter with more precise handling, it also transmits engine vibration directly to the rider. 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. Buell motorcycles built with variants of the Sportster engine have used a rubber mount system since 1987.

The Model K, from which the Sportster evolved, was the first civilian motorcycle produced by Harley-Davidson with hydraulic shock absorbers on both wheels. Common usage calls this a K Model. 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 connecting rods would be inherited by the Sportster along with many other design elements and dimensions.

Introduced in 2007, the XL1200N Nightster included (then) unique elements such as a bobbed rear fender, front fork gaiters, and a side mount license plate. The riding position and 25.3-inch (640 mm) seat height of the Nightster are the same as those of the XL883L Sportster Low - UK version (along with Iron 883 and Forty-Eight) has central number plate, 13.5-inch rear shocks, tapered silencers, and combined LED indicator/tail/brake lights. The bike has a measured HP of 57.2 hp (42.7 kW) (rear wheel) and 64.4 lb·ft (87.3 N·m) (rear wheel) and a top speed of 107 mph (172 km/h) and a wet weight of 564 lb (256 kg). The Harley Iron was released in 2009 as a smaller displacement version of the Nightster. The major differences are blacked out engine, cast wheels instead of laced; and of course the smaller engine displacement. In the 2008 model year, Harley-Davidson released the XR1200 Sportster in Europe, Africa, and the Middle East. The XR1200 had an Evolution engine tuned to produce 91 bhp (68 kW), four-piston dual front disc brakes, and an aluminum swing arm.

Motorcyclist had the XR1200 on the cover of its July 2008 issue, and was generally positive about it in their "First Ride" story, in which Harley-Davidson was repeatedly asked to sell it in the United States.[8] One possible reason for the delayed availability in the United States was the fact that Harley-Davidson had to obtain the "XR1200" naming rights from Storz Performance, a Harley customizing shop in Ventura, Calif.[9] The XR1200 was released in the United States in 2009, in a special color scheme including Mirage Orange highlighting its dirt-tracker heritage. The first 750 XR1200 models in 2009 were pre-ordered and came with a number 1 tag for the front of the bike, autographed by Kenny Coolbeth and Scott Parker and a thank you/welcome letter from Harley-Davidson, signed by Bill Davidson. The XR1200 was discontinued on the United States Market for the 2013 lineup. The bike has a measured HP of 79.26 hp (59.10 kW) (rear wheel) and 67.53 lb·ft (91.56 N·m) (rear wheel) and a top speed of 120.7 mph (194.2 km/h)and a wet weight of 580 lb (260 kg).

In the 2010 model year, Harley-Davidson introduced the XL1200X "Forty-Eight" model. It is similar to the "Dark" Nightster style but has the classic 1948 style small peanut tank, wire wheels, forward-controls, a wider front tire with a fat front end and chopped front fender, a slammed speedo with under mount mirrors, low solo single seat, and low suspension. In the 2012 model year, Harley-Davidson introduced the XL1200V "Seventy-Two" model. It has the classic styling of the early '70s chopper/bobbers that were prevalent during this time. It has the peanut gas tank, wire wheels, white-wall tires, forward-controls, a bit of extra rake and slightly longer front forks, a chopped (bobbed) rear fender, side-mounted license plate, low solo single seat, mini-ape hanger handlebars, and low suspension.[11] The bike has a measured HP of 54.67 hp (40.77 kW) (rear wheel) and 59.81 lb·ft (81.09 N·m) (rear wheel) and a top speed of 108 mph (174 km/h) with a wet weight of 559.5 lb (253.8 kg).
