1901 - In Milwaukee, William Harley, 21, and Arthur Davidson, 20, began experiments on taking the work out of bicycling. They were soon joined by Arthur's brothers, Walter and William.
1902 - The 1902 prototype was a 10.2ci, (167cc), single with 2.125 bore and stroke with a 5" flywheel. It would blow your hat off in a good breeze plus the almost 25mph it could attain.
1903 - The company Harley-Davidson was founded. Many changes were made to the engine design before its builders were satisfied. After the new looped frame was finalized, they were ready to begin production.
1903 - The first Harley-Davidson motorcycle is manufactured: a 25 cubic inch (410cc) atmospheric-inlet-valve single-cylinder. Only 3 Harley-Davidson motorcycles were made in 1903
1904/1905 - Production began in a shed behind the Davidson family home. The machine was a 30 cubic inch (494cc) single which was later nicknamed: The "Silent Grey Fellow" nickname coincides with the new standard grey color.
1906 - Harley-Davidson erected its first building at the current Juneau Avenue site in 1906. Catalogs are produced to advertise the new Silent Gray Fellow
1907 - Harley-Davidson incorporated in 1907. A prototype V-twin motorcycle was built. Although only 150 motorcycles were made that year, 1907 saw the first Harley-Davidson sold
for police duty
1909 - The trademark 45 degree V-Twin engine, introduced in 1909, displaced 49.5 cu in and produced seven horsepower. Top speed: 60 mph. 1909 production was truly massive compared
to previous years (almost 8 times the 1907 production rate) at 1,149 motorcycles
1912 - First clutch mechanism.
1913 - The original 28' x 80' factory had grown to 297,110 square feet. Harley-Davidson began to dominate racing events. 1913 production: 12,904 motorcycles
1914 - Step-starter and internal expanding rear brake.
1915 - Three speed transmission
1920 - Harley-Davidson became the largest motorcycle manufacturer in the world, boasting dealers in 67 countries. Harley-Davidson motorcycle development was evolutionary rather than revolutionary with side-valve machines replacing inlet- over-exhaust designs in the late 1920s. 1920 production: 28,189 motorcycles
1921 - In February 1921, on a Fresno, CA., board track, a Harley-Davidson became the first motorcycle ever to win a race with an average speed over 100 mph
1922 - 74" Twin engine debuts.
1928 - Front wheel brakes were introduced dramatically improving
the safety and handling of Harley-Davidson's cycles.
1929 - After the stock market crash of October 1929, Harley- Davidson sales suffered with everyone else's in the industry. This year saw the introduction of the first 45 ci (750cc) side- valve V-twins, the "D" series. These used the same frame as the singles, which was made possible by mounting the generator perpendicular to the engine. Early Forty-fives lacked the power of their competition, the Indian Scout.
1932 - The 45ci Servicar model was introduced. Cost $450
1933 - The depression hit Harley-Davidson very hard. By 1933, production in Milwaukee had dropped to 3,700 vehicles.
1936 - Harley-Davidson wasted no time building momentum out of the depression, introducing its EL model, featuring the 61 ci (1000cc)overhead valve engine, also known as the "Knucklehead" This engine, termed the "61 OHV" in factory literature and called the Sixty-one in every day circles was a mid-season 1936 model. This, in the opinion of many, is the motorcycle that saved Harley-Davidson. At that time, for the first time, a major American motorcycle company was building a big motorcycle with overhead valves (this coming shortly after the major engineering difficulties of the 1929 Forty-five and the 1930 Seventy-four. Also introduced this year was the 80ci
side valve twin engine. Despite the specter of the depression Harley-Davidson produced almost 10000 motorcycles in 1936.
1937 - William A. Davidson dies.
1941 - Almost immediately after the Japanese attacked Pearl Harbor, Harley-Davidson's entire motorcycle output was produced for Allied use. By the end of World War II, 90,000 WLA army- version motorcycles had been built and shipped.
1942 - Walter Davidson dies at age 65.
1943 - Bill Harley dies at age 66.
1947 - 74" OHV Big Twin engine.
1948 - Harley-Davidson introduced a new 74 cu in. engine
with hydraulic valve lifters and aluminum heads. The "Panhead" was born. 1948 production: 31,163 motorcycles
1949 - The Hydra-Glide debuts
1950 - Arthur Davidson dies at age 69.
1953 - Harley-Davidson celebrates its 50th anniversary while its oldest and closest competitor, Indian, went out of business, leaving Harley-Davidson as the sole survivor in a
once overcrowded American motorcycle marketplace. Harley- Davidson expanded its line to include two-stroke engines and even a scooter. 1953 production: 14,050 motorcycles.
1957 - XLH Sportster debuts.
1958 - The Duo Glide (based on the earlier Hydra-Glide model) was introduced, featuring a hydraulic rear shock suspension
to go with the hydraulically dampened front fork. Also in
1958, Carroll Resweber won the first of four consecutive
AMA Grand National Championships.
1959 - XLCH Sportster.
1960 - The "Topper" a fiberglass motor scooter, was introduced. Harley-Davidson teams up with
Italian manufacturer Aeronautica Macchi S.P.A. to produce a line of smaller bikes including the Shortster and Sprint models. Italian-built lightweights were sold in America under the Harley-Davidson name. The Topper featured a pull-cord starting mechanism much like that of a lawn-mower.
1963 - Willie G. Davidson joins Harley-Davidson as design director.
1965 - With the addition of an electric starter, the Duo Glide became the Electra Glide in 1965, which was also the last year of the "Panhead" engine. Harley-Davidson became a publicly-held company when it issued stock in 1965.
1966 - The introduction of the "Shovelhead" engine. Production: 36,310 motorcycles.
1967 - Electric start Sportster.
1969 - Merger with American Machine and Foundry Company (AMF).
1971 - FX 1200 Super Glide, considered the first true factory custom. Joe Smith, riding a drag bike powered by a single Harley-Davidson motor, was the first to break the nine-second barrier in motorcycle drag racing.
1972 - 1000 cc XLH/XLCH Sportster. First disc brakes on a Harley.
1974/75 - Chassis manufacturing and final assembly operations moves to a plant in York, Pa. Engine and transmission operations remained in Milwaukee, along with the corporate headquarters. 1975 production: 75,403 motorcycles.
1978 - In 1978, Harley-Davidson sold the Italian operation (the old Aermacchi company) and the sales of Italian motorcycles with the Harley-Davidson name was halted.
1978 - 75th Anniversary models debuts.
1978 - FLH 80 Electra-Glide debuts.
1978 - First electronic ignition on a Harley.
1979 - FXS 80 Low Rider debuts.

Many people over the years have become suitably confused by Harley-Davidson's model designations. And rightfully so. The alpha-designations merely exist, the letters seemingly drawn out of thin air. Today, even though we have only two basic engine designs to deal with, the Sportster X and Big Twin F, the number of letters for one model would do credit to a bowl of soup. For example, the 1995 model line included the FLHTCI and the FXSTSB - mouthfuls both. Let us analyze these. First, the FLHTCI bagger. The F stands for the medium compression 74-inch OHV engine introduced in 1941; the L stood for the slightly more powerful "Special Sport Solo" version. The H was tacked on in 1955, indicating the "Super Sport Solo". In 1978 the 80-inch engine was introduced as an option, and by 1981 the F model designation meant an 80-incher. The T was added in 1983 to indicate that this was a touring machine with bags and batwing fairing, and the C also came in that year to show that this model had "classic" looks and a higher price tag. The I is the first use of that letter, and is alphabetical proof that this model is fuel-injected rather than carbureted.
Got all that?
Now the FXSTSB. The F has been demonstrated. The X shows that this big twin had the lighter, Sportster-type front end inaugurated in 1971. The ST (in this case those letters have to stand together) stands for the Softail chassis design, introduced in 1984. The second S is the Springer front end, intro-Ed in 1988. The B is for the new 1995 model, the Bad Boy.
Confused? And rightfully so. While all these letters might not make much sense to the average Harley enthusiast, they help a lot in the parts department - especially when prefaced by a year, such as an 1984 FXRT. Often the first alpha-designation a Harley enthusiast interested in Harley history hears is about someone's JD model, indicating the 74-inch V-twin introduced in 1921, but the lettering goes back long before that.
Up to 1908, there was only one Harley model per year, a battery-fired single cylinder, so and further designation than the year was superfluous: i.e., an 1907 Harley. But in 1909, the factory offered four singles, with either 26- or 28- inch wheels (wheels were measured from the outer edge of the tire back then), and either battery or magneto ignition. These were referred to as the Model 5 (fifth year of production, which, for Harley-Davidson purposes, began in 1904) with battery and 28s, the Model 5-A with mag and 28s, 5-B with battery and 26s and 5-C, mag/26. The abortive twin was called the 5-D.
In 1910, the single-cylinder racer was called the 6-E. In 1912, things got real complicated with both chain and belt drive being offered, and a clutching mechanism designated by an X; all wheels were the 28-inch variety. The basic single was the Model 8, the mag-fired twin with "freewheel control" and chain drive was called the Model X-8-E.
In 1914, we see the first use of the F letter, a 61-inch magneto twin with two-speed gearbox. In 1915, the J model appeared, the twin with three-speed transmission and battery ignition. That was also the year of the first K model, a racing twin.
In 1916, the year designation was changed from year of production to calendar year, so it was not 12-F, but 16-F. Eight models were available that year: the F, J, E, R and T twins, and C, B and S singles. Already Harley was complicating things, as the E of 1910 was a racing single, while the E of 1916 was a one-speed twin. The heck with this; let us start with the alphabet and go right through to see how many letters have been used, and how many times. When you see a "/", that means the letter(s) was secondary (FL), tertiary (FLH), etc. To try to keep this under control, I will start with the models that were in the 1920 line, and ignore what went on before that date.
