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 ('flat head') 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. [1]

Contents

The original Sportster line was discontinued in Europe in 2020 because the engine failed to meet the stricter Euro 5 emissions standards. [2] An all-new model, called the Sportster S and equipped with the Revolution Max engine, was introduced in 2021. It was 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. [3]

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. 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. (1930–1936), Models U and UL (1937–1948), and the 80.0 cu in (1,311 cc) models VH and VLH (1935–1936), models UH and ULH (1937–1941), have four separate cams, sporting one lobe per cam.

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 featured the same 0.731-inch (18.6 mm) diameter body and 0.855-inch (21.7 mm) diameter roller follower used since 1929. The company used similar cam followers for decades, with minor changes, from 1929 to the 1980s.

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. In 2003, Harley Davidson produced a limited number of 100th anniversary model Sportsters. They are identified by the 100th anniversary paint schemes and plaques attached to the sheetmetal, speedometer housing, and engine. 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.

Model K series

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.

2008 XL1200N Nightster

Introduced in 2007, [11] 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). [12]

The Harley "Iron" was introduced in 2009 as a smaller-displacement version of the Nightster. The major differences are blacked-out engine, cast wheels instead of laced; narrower handlebars; and of course the smaller 883 cc engine displacement compared to the Nightster's 1200 cc. The Nightster was discontinued in 2012. [13]

The Nightster name returned in 2022 with a 975cc engine. [14]

XR1200

2010 Harley-Davidson XR1200 Sportster

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. [15] 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, California. [16] 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 after 2012. For 2012, the XR1200X model had upgraded suspension front and rear. 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). [12]

Forty-Eight

Harley-Davidson Sportster Forty-Eight

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. [7]

Seventy-Two

In the 2012 model year, Harley-Davidson introduced the XL1200V "Seventy-Two" model, sold until 2016. 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. [17] 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). [12]

Roadster

In the 2016 model year, Harley-Davidson introduced the XL1200CX "Roadster" model. This is the sporty Sportster with café bike styling and stance. With mid-position pegs and a slammed drag bar give a slight lean-forward riding position. [18] A 43mm inverted cartridge fork and in the back preload-adjustable emulsion-type shocks help the roadster to have the greatest lean angle of any Sportster. Also standard are twin 300mm floating disc brakes and a tachometer. The bike has a measured HP of 65.4 hp (48.8 kW) (rear wheel) and 69.7 lb⋅ft (94.5 N⋅m) (rear wheel). [19]

Sportster S

In 2021, Harley-Davidson launched the Sportster S with the new Revolution Max 1250T engine and described it as a "sports custom motorcycle". In an independent review, UK publisher Bennetts commented that: "Despite the Sportster moniker, the new bike’s specs mean it’s got more in common with the old V-Rod than its namesakes. By the end of its life, the V-Rod had a 1247cc, water-cooled, DOHC V-twin making 125hp, putting it within spitting distance of the new Sportster’s 1252cc and 121hp. But the old bike was a much heftier machine, coming in at around 300kg depending on which version you picked, where the Sportster S is a relatively lithe 228kg ready-to-ride. The result means the Sportster will be a significantly better-performing machine, both in a straight line and around corners, than the old V-Rod." [20]

Current models

The Sportster is offered in a number of different models. The 2022 models, which are not all offered in the same countries, are:

Harley-Davidson manufactured the last Evolution Sportster, a Gunship Gray 883, on November 18, 2022.

Buell

Buell started with water-cooled two-stroke square-fours and ended with a water cooled four-stroke V-Twin, but the vast majority of their bikes used reworked 883 and 1200 Sportster engines. With Buell-designed heads, barrels, and in 1999 fuel injection, these all led to an increase in horsepower. They also had rubber mounting and a fan to cool the rear cylinder. [21]

A softail motorcycle intentionally looks like vintage motorcycles with a rigid hard-tail frame that has a triangle of steel tubes at the rear axle, as on a bicycle frame, but on a Softail these tubes are actually a triangular swingarm, with the shock absorber(s) hidden, as opposed to clearly visible regular twin shocks on both sides of the rear wheel on standard bikes. Since the introduction of the Harley-Davidson FXST Softail in 1983 as a registered trademark of the Motor Company, softail has become a genericized trademark for other models of cruiser motorcycles with rear suspensions hidden for retro style reasons. This was done even though the rear wheel was often hidden behind bags or exhaust pipes.

The Evolution engine is an air-cooled, 45-degree, V-twin engine manufactured from 1984 by Harley-Davidson for the company's motorcycles. It was made in the 1,340 cc (82 cu in) displacement for Harley-Davidson Big V-twins bikes, replacing the Shovelhead engine until 2000 when the last EVO was placed in a production factory custom FXR4. In 1999, it was replaced by the Harley-Davidson Twin Cam 88 in the Touring and Dyna model and in 2000 in the Softail models. Also available in the Sportster model beginning in 1986, it was made in the 1,100 cc (67 cu in) displacement until 1988 and is still made in the 883 cc (53.9 cu in) and 1,200 cc (73 cu in) displacements for the Harley-Davidson Sportster, replacing the ironhead Sportster engine.

The Harley-Davidson Twin Cam are motorcycle engines made by Harley-Davidson from 1998 to 2017. Although these engines differed significantly from the Evolution engine, which in turn was derived from the series of single camshaft, overhead valve motors that were first released in 1936, they share a number of characteristics with nearly all previous Harley-Davidson engines. Both engines have two cylinders in a V-twin configuration at 45°, are air-cooled, and activate valves with push-rods. The crankshafts have a single pin with a knife and fork arrangement for the connecting rods. These are sandwiched between a pair of flywheels.

<span class="mw-page-title-main">Harley-Davidson FL</span> HD FL 1200 Lowrider

Harley-Davidson FL is a model designation used for Harley-Davidson motorcycles since 1941, when F referred to the new large capacity 74 cui (1200cc) variant of the V-2 Overhead valve engine (″Knucklehead″) that was introduced in 1936 as Model E with 61 cui (1000cc). The presence of an additional letter L indicated higher compression, offering more power but requiring higher octane gasoline. In 1950s, the low compression version was discontinued, and in 1952 also the low capacity EL, making FL the standard engine and model designation for decades to come.

The Harley-Davidson Super Glide was a motorcycle made by the Harley-Davidson. Reputed to be the first factory custom motorcycle, it originated Harley-Davidson's FX series of motorcycles by mating Sportster components, most notably the front end, with the chassis of their larger big twin motorcycles. Super Glide models from 1991 to 2018 were based on the Dyna Glide chassis which has a wider variety of front ends and trim levels, and for a time filled the intermediate niche between the smallest and largest Harley-Davidson models; the Dyna platform has since been discontinued for the 2018 model year in favor of the new Softail frame, with some models from the Dyna nameplate being carried over to the Softail line.
