The Harley-Davidson Fat Boy, is a V-twin softail cruiser motorcycle with solid-cast disc wheels. [2] Designed by Willie G. Davidson and Louie Netz, Harley-Davidson built a prototype Fat Boy in Milwaukee for the Daytona Bike Week rally at Daytona Beach in 1988 and 1989. [3] [4] Fat Boys produced from 1990-2017 are coded FLSTF, and FLFB (& FLFBS) from 2018.
An oft-repeated false etymology claims that the name comes from a contraction of Fat Man and Little Boy, the atomic bombs dropped on Japan during WWII, as a symbolic insult to Japanese motorcycles. [5] This has been debunked, as the name "Fat Boy" actually comes from the observation that the motorcycle is somewhat wider than other bikes when viewed head-on. [6] [5] In a 2015 interview, Scott Miller, Harley-Davidson's vice president of styling and product development, confirmed that the name was simply descriptive and had nothing to do with Harley's Japanese competitors. [7]
In the mid-1970s, mechanical engineer Bill Davis designed and built a predecessor to the Softail and patented the design in 1976. [8] Davis sold his patents, prototype, and tooling to Harley-Davidson in January 1982. [9] The Fat Boy was one of numerous Harley-Davidson models built on the Softail frame.
The 2018 Softail frame has a modified swingarm with a Showa rear monoshock suspension mounted beneath the seat, replacing earlier twin shocks. So as to provide a more comfortable and better controlled ride with improved handling, the front forks contain a Showa "Dual Bending Valve" (SDBV), [13] a cartridge simulator using two valves to control compression and rebound damping, giving linear damping characteristics proportional to fork stroke speed. Harley-Davidson claims the 2018 chassis is stiffer and lighter than earlier Softail and Dyna platforms. [14] Further upgrades include an LED headlight and 18-inch "Lakester" rims, with wider 160mm front and 240mm rear tires. [15] [16]
For 2020, the Fat Boy is only available with the Milwaukee-Eight 114 engine. Harley-Davidson also produced a 30th Anniversary edition for 2020. [17]
It is one of Harley-Davidson's best selling models and has appeared prominently in a number of TV shows and movies. [3] The Fat Boy earned a place in American pop culture after appearances in the movie Terminator 2: Judgment Day . One of the motorcycles used in Terminator 2 is displayed at the Harley-Davidson Museum. It appeared again in Terminator Genisys . [2] [18] [7] [19]
Harley-Davidson, Inc. is an American motorcycle manufacturer headquartered in Milwaukee, Wisconsin, United States. Founded in 1903, it is one of two major American motorcycle manufacturers to survive the Great Depression along with its historical rival, Indian Motorcycles. The company has survived numerous ownership arrangements, subsidiary arrangements, periods of poor economic health and product quality, and intense global competition to become one of the world's largest motorcycle manufacturers and an iconic brand widely known for its loyal following. There are owner clubs and events worldwide, as well as a company-sponsored, brand-focused museum.
Indian Motorcycle is an American brand of motorcycles owned and produced by American automotive manufacturer Polaris Inc.
Buell Motorcycles is an American motorcycle manufacturer based in Grand Rapids, Michigan, United States. It was founded in 1983 by ex-Harley-Davidson engineer Erik Buell. Harley-Davidson acquired 49 percent of Buell in 1993, and Buell became a wholly owned subsidiary of Harley-Davidson by 2003. On November 17, 2006, Buell announced that it had produced and shipped its 100,000th motorcycle.
The Honda Shadow refers to a family of cruiser-type motorcycles made by Honda since 1983. The Shadow line features motorcycles with a liquid-cooled 45 or 52-degree V-twin engine ranging from 125 to 1,100 cc engine displacement. The 250 cc Honda Rebel is associated with the Shadow line in certain markets.
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.
Erik F. Buell is the founder, former chairman and chief operations officer of the Buell Motorcycle Company, which eventually merged with Harley-Davidson Corp. Buell is a pioneer of modern race motorcycle technology. Buell is also the founder of Erik Buell Racing.
Victory Motorcycles was an American motorcycle brand based in Spirit Lake, Iowa, United States. It began selling its vehicles in 1998, and began winding down operations in January 2017 to be succeeded by the revived traditional American motorcycle brand Indian, which are both owned by parent company Polaris Industries.
The Vulcan name has been used by Kawasaki for their custom or touring bike since 1984, model designation VN, using mostly V-twin engines ranging from 398 to 2,053 cc.
The Triumph Rocket III is a three-cylinder motorcycle made by Triumph Motorcycles Ltd. At 2,294 cc (140.0 cu in) it had the largest-displacement engine of any production motorcycle until 2019 when Triumph released the Triumph Rocket 3.
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.
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 1964 Ducati Berliner 1260 Apollo was a prototype 1,257 cc (76.7 cu in) V4 engine motorcycle producing 100 bhp (75 kW) and capable of over 120 mph (190 km/h). It was never put into production, but did influence other production Ducatis that followed. Both Ducati and their United States distributor, Berliner Motor Corporation, were experiencing declining sales of existing small-capacity single-cylinder models, and sought to create a bike to compete with Harley-Davidson. Berliner Motor was keen to have a model that could win lucrative police motorcycle supply contracts, and that could also sell as a civilian touring bike.
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.
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.
The Kawasaki Vulcan 900 Classic motorcycle is a mid-sized motorcycle cruiser made by Kawasaki, first introduced in 2006. The cycle follows the formula of a smaller yet capable engine fitted into a one-size up frame, a popular combination also in use by Honda, Suzuki, and Yamaha in their respective cruiser lines.
The Harley-Davidson VRSC, or V-Rod, is a line of V-twin cruiser motorcycles made by Harley-Davidson from 2002 until 2017. They are often called muscle bikes for their relatively high power output. The V-Rods are the first street motorcycles made by Harley-Davidson with overhead camshafts and liquid cooling.
Harley-Davidson CVO for motorcycles are a family of models created by Harley-Davidson for the factory custom market. For every model year since the program's inception in 1999, Harley-Davidson has chosen a small selection of its mass-produced motorcycle models and created limited-edition customizations of those platforms with larger-displacement engines, costlier paint designs, and additional accessories not found on the mainstream models. Special features for the CVO lineup have included performance upgrades from Harley's "Screamin' Eagle" branded parts, hand-painted pinstripes, ostrich leather on seats and trunks, gold leaf incorporated in the paint, and electronic accessories like GPS navigation systems and iPod music players.
The Harley-Davidson Milwaukee-Eight engine is the ninth generation of "big twin" engines developed by the company, but only Harley's fourth all-new Big Twin in 80 years, first introduced in 2016. These engines differ from the traditional Harley Big Twin engines in that there are four valves per cylinder, totaling eight valves, hence the name. It also marked a return to the single-camshaft configuration as used on previous Harley Big Twin Engines from 1936 to 1999. In addition, the engines all have internal counterbalancers, whereas Twin Cams were counterbalanced only on Softail models, where the engine was rigidly mounted.
The Honda 650 cc standard and sport motorcycles are a range of 649 cc (39.6 cu in) inline-four standard and sport motorcycles made by Honda since 2013. The line includes the CB650F standard or 'naked bike', and the CBR650F sport bike that replaced outgoing CB600F Hornet.
Davis relented and signed the deal on January 6, 1982, selling Harley the Sub Shock Wide Glide prototype, the patents for the design, all the tooling, and six complete Sub Shock frames.
