Harley-Davidson History

1870 Birth of William A. Davidson, Milwaukee, WI.
1876 Birth of Walter Davidson, Milwaukee, WI.
1880 Birth of William S. Harley, Milwaukee, WI. As he was born just after Christmas, his parents gave him the middle name "Sylvester".
1881 Birth of Arthur Davidson, Milwaukee, WI.
1901 William S. Harley, aged 21, completes a blueprint for an engine to fit into a bicycle.
1903 Harley and Arthur Davidson build the first production Harley-Davidson. It features a 3-1/8" bore and a 3-1/2" stroke yielding 7.07 cubic inches (116cc). They make a more powerful motor with the assistance of Ole Evinrude - better known as the inventor of the outboard motor. It is designed for use on the wooden velodromes where popular bicycle races are held. Harley and Davidson work in a 10 x 15 foot shed on Chestnut Street (later named Juneau Avenue) which is still the address of Harley-Davidson's head office.
1904 The first Harley-Davidson dealer, C.H. Lang of Chicago, opens for business.
1906 A new 28 x 80 foot factory is built on Chestnut Street. The company has grown to have six employees. It produces its first catalog, and coins the nickname "Silent Gray Fellows". It's a reference to the fact that bikes were painted dove gray, and that they were quietly reliable. (Evidently, the company's founders were unaware that loud pipes save lives.)
1907 William A. Davidson joins the firm. Harley-Davidson Motor Company is incorporated, with stock shared by the Harley and the three Davidson brothers.
1908 Walter Davidson scores a perfect 1,000 points at the 7th Annual Federation of American Motorcyclists Endurance and Reliability Contest. Three days after the contest, Walter sets the FAM economy record at 188.234 miles per gallon. Perhaps impressed with that reliability, Detroit becomes the first city to buy a Harley-Davidson for police use.
1909 "The Motor Company" makes its first V-Twin. It has a displacement of 49.5 cubic inches and produces seven horsepower.
1910 The 'Bar & Shield' logo is used for the first time in 1910 and was trademarked one year later.
1911 The 'F-head' single cylinder engine is introduced and will remain in use until 1929. (This is a reference to the shape of valve ports). It is an inlet-over-exhaust design, with an overhead intake valve (int the head like a modern motor) but a "side" exhaust valve which is in the cylinder.
1912 Harley-Davidson begins exporting motorcycles to Japan. Construction begins on a six-story headquarters. The Parts and Accessories Department is formed. The company has more than 200 dealers across America.
1913 The Racing Department is formed, under the control of Bill Harley.
1914 Sidecars are made available. Some models are briefly available with a two-speed transmission in the rear hub. Also, belts go out of fashion - for the moment. Harley-Davidson is one of the last motorcycle manufacturers to switch from leather drive belts to chains. The leather belts slipped, stretched and rotted, so chains are a big improvement.
1915 Harley-Davidson motorcycles become available with three-speed sliding-gear transmission with final and primary drive on the same side.
1916 The Enthusiast magazine is published for the first time.
1917 About a third of the company's production is purchased by the Army. To train Army mechanics, the company starts the Quartermasters School. After the war, it will be retained as the Service School, providing factory-trained mechanics for dealers.
1918 Almost half of all Harley-Davidson motorcycles produced are sold for use by the U.S. Military in World War I. After armistice is signed, Corporal Roy Holtz becomes the first American soldier to enter Germany. He does so on a Harley-Davidson motorcycle.
1919 The 37-cubic inch Sport model is introduced. It's horizontally opposed, fore-and-aft V-Twin.

1920 Now the largest motorcycle manufacturer, Harley-Davidson boasts over 2,000 dealers in 67 countries. The factory racing team, already known as "The Wrecking Crew" because it's become so dominant in American racing, has a small pig as a mascot. The bikes are nicknamed "hogs" as a result.
1925 The company adopts teardrop-shaped gas tanks (previously they were flat-topped) that give its machines a very distinct look. Joe Petrali becomes one of the first salaried "factory racers".
1926 Single-cylinder motorcycles are sold for the first time since 1918. Models A, AA, B and BA are available in side-valve and overhead-valve engine configurations.
1928 The first two-cam engine is made available on the JD series motorcycles. The bike can reach a top speed between 85 and 100 mph. Luckily, this year all Harley-Davidson models are also available with a brake on the front wheel. Surprisingly, few Harley-Davidson riders use them, even to this day.
1929 The D model is introduced with a rugged, 45 cubic inch Flathead V-Twin engine. The "Flathead" motor will be sold in various guises for over 40 years. The stock market crash heralds the Great Depression. In 1929, the company sells 21,000 motorcycles. It's the strongest of the dozens - if not hundreds - of motorcycle brands that were launched in the first three decades of the century; only a handful will survive into the fourth.
1932 The three-wheeled Servicar begins its 41-year run. (Sure they were used to deliver great corned-beef sandwiches, but they were also used by the guys who wrote 410,000 parking tickets, too.) In racing, Joe Petrali begins a string of five consecutive national championships in dirt track, as well as four consecutive hill-climbing titles. (In those years, the championship was decided in a single race.)
1933 The company sells only 4,000 motorcycles this year. To reduce costs for competitors, the AMA creates a new racing class, Class C, based on production equipment and allowing for limited modifications. Although the original, prototype-based Class A persists, the AMA emphasizes the new class. Purists resent the change.
1935 Alfred Child, the company's agent in Asia, realizes that currency exchange rates are killing sales in Japan. He convinces the company to license production of its motorcycles Japan. The Sankyo Seiyakyo Corporation purchases tooling and begins producing Harley "clones". They are sold under the name Rikuo, which means "King of the Road".
1936 Introduction of the EL, an overhead-valve, 61 cubic inch powered bike, which earns the nickname of 'Knucklehead' because of the shape of its rocker boxes. The company also introduces and 80 cubic inch side-valve engine.
1937 Petrali sets a land speed record of over 136 mph with a streamlined Knucklehead. The first WL models are produced. William A. Davidson dies, two days after signing an agreement that makes the company a union shop.
1938 Ben Campale wins the Daytona 200 on a 45 cubic inch WLDR. The race was run on the 3.2 mile beach course. The Jackpine Gypsies hold the first Black Hills rally in Sturgis.
1941 The United states enters World War II. The production of civilian motorcycles is almost entirely stopped for the production of the Harley military bikes for the war.
1942 When U.S.soldiers capture their first "Wehrmacht"-issue motorcycles in North America, they find that the BMWs and Zundapps are better suited to tough military duty. Harley-Davidson and Indian each develop about 1,000 machines for evaluation, with shaft drives and Flat-Twin motors copied from the Germans. They are never widely issued, though the machines cost Uncle Sam a whopping $35,000 each. Walter Davidson dies.
1943 William S. Harley dies.
1945 The war finally ends. Between 1941-45 the company produced 90,000 WLA models for military use.
1946 The 45 cubic-inch, Flathead, WR production racer is made. It conforms to stricter Class C AMA rules, which are intended to reduce costs for competitors. It's a Flathead, because in Class C, Flatheads are allowed to displace 750cc, while OHV motors are limited to 500cc.
1948 The company's 61 and 74 cubic inch OHV engines are updated with aluminum heads and hydraulic valve lifters. Also new are the one-piece rocker covers, which resemble cake pans, earning the motor the nickname 'Panhead'. As part of Germany's war reparations, the Allies loot German patents. The fine, small two-stroke motors built by DKW (seen in that company's popular RT125) are copied by BSA (the Bantan) and Harley-Davidson, which produces the model S that will come to be known as the "Hummer".

1949 Hydraulic front forks make their first appearance on the new Hydra Glide models.
1850 Arthur Davidson dies.
1952 Returning servicemen seem to favor the lighter British Twins they saw "over there". In response, Harley-Davidson creates the 45 cubic inch side-valve K model. It's a unit-construction motor - the crankcases and gearbox are one set of castings.
1953 Indian goes into its long, painful death throes. Harley-Davidson, which celebrates its 50th Anniversary this year will be the only real motorcycle manufacturer in the U.S. for the rest of the century. The aging WR and WRTT production racers are no match for the British 500s now invading the dirt tracks (and a few road coursers) of America.
1955 The new KR begins a run of seven consecutive Daytona 200 victories, which will include the last race run on the old beach course and first one run at the new Daytona International Speedway.
1957 The Sporster is introduced. It is basically a larger-displacement version of the K motor, fitted with an OHV head. At 55 cubic inches, it offers performance to rival anything coming out of England (at least, anything coming out of England without a "Vincent" tank badge.) has an overhead valve engine.
1958 Hydraulic rear suspensions appear on the Duo-Glide.
1960 Harley-Davidson acknowledges the market potential of smaller machines. The company makes its first and only scooter, the Topper. It also purchases a half-interest in the Italian company Aermacchi, which produces fast and stylish single-cylinder machines of up to 350cc. Brad Andres wins the last Daytona 200 run on the sand. 2nd through 13th places all go to riders on KRs.
1961 The first Aermacchi design to reach America is the Harley Davidson Sprint. Short-track racers are quick to realize that its good power and low center of gravity make it a winner.
1962 Harley-Davidson acquires the Tomahawk boat company and starts to learn about the uses of fiber glass.
1964 The humble Servicar is the first of the company's machines to be fitted with an electric starter.
1965 The Duo Glide is fitted with an electric starter, and thus becomes the Electra Glide.
1966 Riders clamoring for more power cause the company to update the old Panhead motor. The new engine has rocker boxes that resemble coal shovels. Hence, the new mill gets the nickname "Shovelhead". This basic motor will remain in production for 20 years.
1968 After years of increasingly vociferous lobbying, the import manufacturers convince the AMA rules committee that the 250cc displacement advantage given to Flathead motors is unfair. the AMA declares that, bikes with overhead valves (all the British and Japanese models) can also displace up to 750cc. Harley-Davidson lobbies to delay the implementation of the new rule for one more season.
1969 Although Harley-Davidson stock is publicly traded, it is still a relatively closely held corporation. The shareholders - perhaps sensing that the "Japanese invasion" is about to open a new front in the heavyweight category, with the Honda CB750 Four - sell the company to the American Machine and Foundry Company (AMF). AMF has hitherto been known to the American consumer as a maker of bowling balls, but it is in fact a large, diversified manufacturer. AMF could have risen to the challenge presented by the sophisticated and comparatively affordable Honda. Instead, AMF's managers really blow it. Harley-Davidson quality plummets. Before long, dealers are forced to rebuild motors under warranty and magazines are brutally critical of test bikes. Used Harleys are described as "pre-AMF" in classified ads.
1970 The racing department creates a new production racer, the XR-750. The motor is basically a destroked Sportster until. It gets off to an inauspicious start; none of the factory entries reach the finish in the Daytona 200. The first Harley across the line is an ancient KRTT, ridden by Walt Fulton III.
1971 By mating the spare front end of the XL series with the frame and motor of the FL series, the company creates the first cruiser - the FX1200 Super Glide.
1973 A new assembly plant is opened in York, PA.

1977 Although most Harley fans would rather forget the years when the company was owned by AMF, there is one AMF-era bike that's highly sought-after by collectors: the 1977 XLCR. That "CR" stands for Cafe' Racer and the bike was only the second major project for Willie G. Davidson (the grandson of one of the founders). While the model is prized now, it was rejected by Harley customers. Only 3,100 were sold and the model was dropped a year later - although dealers still had unsold XLCRs cluttering their showroom floors well into the 1980s. The FXS Low Rider is introduced.
1979 The FXEF "Fat Bob" is introduced. It's called fat because of its dual gas tanks, and bob on account of its bobbed fenders.
1980 The FLT is introduced. It has rubber-isolated drive-train and an engine and five-speed transmission which are bolted together. Belts come back into fashion: a Kevlar belt replaces the chain as the final drive on some models. The FXB Sturgis, featuring and 80 cubic inch engine, and FXWB Wide Glide are introduced.
1981 After years of AMF mismanagement, Harley-Davidson has lost almost all customer loyalty and profits are in a free-fall. When a group of company executives led by Vaughn Beals offers to buy the division for $75 million, AMF quickly agrees. Beals leads an amazing corporate turnaround. He funds new product development and implements world-class quality control. It's impossible to know what would have happened to the Harley-Davidson brand if Beals had not risen up to save it, but it's certain that no one else could have done a better job at rehabilitating it.
1982 The FXR/FXRS Super Glide II are introduced, featuring a rubber isolated, five-speed power-train. The company adopts a just-in-time inventory system on the manufacturing side, which helps to lower cost and improve quality.
1983 The Harley Owners Group (HOG) is formed. The company petitions the International Trade Commission (a branch of the U.S. federal government) to impose a tariff on Japanese motorcycles of over 700cc. As a result, many Japanese motorcycles that are sold as 750cc models in the rest of the world are sleeved-down to 700cc for the U.S. market.
1984 The 1340cc V2 Evolution engine appears on five models. Although it's been in development since the AMF era, the motor proves the newly independent company has turned the corner in terms of build quality. Is is far more reliable and oil-tight. The Softail, which features concealed rear suspension and evokes the rigid-framed hogs of 30 or 40 years ago, meets with commercial success.
1986 Harley-Davidson diversifies with acquisition of the Holiday Rambler motor home company.
1987 The company makes its Initial Public Offering. Stock is traded on the NYSE, with the ticker symbol of HOG. The company petitions the ITC to relax the tariff on imported motorcycles, a year before it was scheduled to lapse. The move serves notice that Harley-Davidson is capable of competing on a level playing field, despite the fact that the Japanese companies now all make V-Twin cruisers that compete directly with the American offerings.
1988 Exploiting customers' love of traditional styling, the Springer front end returns on the FXSTS Springer Softail.
1990 Introduction of the FLSTF Fat Boy.
1991 Introduction of the first motorcycle in the Dyna line, the FXDB Dyna Glide Sturgis.
1992 Harley-Davidson is the first company to equip all its models (except for a handful of racing motorcycles) with drive belts. Modern drive belts provide a smoother ride than chains, last longer (questionable), and free riders from the drudgery of chain lubrication and adjustment.
1993 Harley-Davidson buys a minority interest in the Buell Motorcycle Company.
1994 The company enters the AMA Superbike Championship, fielding the water-cooled, DOHC VR1000. AMA rules specified that the company had to also build and sell 2,000 machines for road use, a process called "homologation". So, you may wonder, why have you never seen a road-going VR1000 if 2000 were sold? Because the model homologated in Poland. By selling it there, Harley avoided U.S. liability and Poland's lax laws allowed the barely-modified race bike to be legally licensed. Despite being ably ridden by Miguel Duhamel, Pascal Picotte, Chris Carr and Scott Russell, the VR1000 will never win an AMA race.
1995 Harley-Davidsons are equipped with fuel injection for the first time.

1996 Sales of parts and accessories are an increasingly important part of the business - a fact reflected in the new, 250,000 square feet facility the company opens in Franklin, WI.
1997 A new 217,000 square foot design center opens in Milwaukee. FL engine production moves to a newly purchased plant in Menomonee Falls. A new 330,000 square foot plant in Kansas City takes over the production of Sportsters.
1998 The company opens its first foreign factory in Manaus, Brazil. The remaining shares of Buell are also acquired.
1999 The Touring and Dyna lines receive the new Twin Cam 88.
2000 Despite spending tens of thousands of dollars in legal fees in the mid-1990s - and having initial success in its efforts to trademark the "potato-potato" sound of Harley motors - the company drops its U.S. Patent Office application. Harley-Davidson's vice president of marketing, Joanne Bischmann, tells reporters, "I've personally spoken with Harley-Davidson owners from around the world and they've told me repeatedly that there is nothing like the sound of a Harley-Davidson motorcycle. If our customers know the sound cannot be imitated, that's good enough enough for me and for Harley-Davidson".
2001 The VRSCA V-Rod is introduced. The motor - which was designed with input from Porsche - is fuel injected, has overhead cams, and liquid cooling.
2003 It is estimated that 250,000 people come to Milwaukee to celebrate The Motor Company's 100th Anniversary.
2006 Fittingly, the 2006 model Dyna motorcycles come with six-speed transmissions. The company announces a major new museum, scheduled to open in Milwaukee in 2008.
2007 Harley upgrades its Big Twin motor, stroking it out to 96 cubic inches and earning the moniker "Twin Cam 96". The six-speed transmission from the Dyna line is added across the board.
2008 The Motor Company opens its impressive new museum in time for Harley's 105th Anniversary.
