Twistgrip
A twistgrip is a handle that can be twisted to operate a control. It is commonly found as a motorcycle's right handlebar grip to control the throttle, but is sometimes found elsewhere, such as on a bicycle as a gearshift, and in helicopters. History The first use of the twist grip throttle control was on the Roper steam velocipede of 1867-69. Rather than a sleeve that rotated around the handlebar, Sylvester H. Roper's steam motorcycle's entire handlebar rotated, with a dual mode operation. When rotated forward it opened the throttle, and when rotated backwards it applied the spoon brake. '' Motorcycle Consumer News'' design columnist Glynn Kerr said that pioneering this technology was a point in favor of the Roper's precedence as the first motorcycle, in response to '' Cycle World'' Technical Editor Kevin Cameron's position that the 1885 Daimler ''Reitwagen'' was more deserving because it used the more successful technology, internal combustion rather than steam.

Roper Steam Velocipede
The Roper steam velocipede was a steam-powered velocipede built by inventor Sylvester H. Roper of Roxbury, Boston, Massachusetts, United States sometime from 1867–1869. It is one of three machines which have been called the first motorcycle, along with the Michaux-Perreaux steam velocipede, also dated 1867–1869, and the 1885 Daimler ''Reitwagen''. Historians disagree over whether the Roper or the Michaux-Perreaux came first. Though the ''Reitwagen'' came many years later than the two steam cycles, it is often labeled as the "first motorcycle" because there is doubt by some experts whether a steam cycle should meet the definition of a motorcycle. After his initial prototype of the late 1860s, Roper built a new and revised version in 1894, based on the then state of the art safety bicycle frame type. Sylvester Roper died of an apparent heart attack while riding this machine in 1896. An 1869 Roper machine is now in the Smithsonian Institution, and one from 1868 is in priva ...

Daimler Reitwagen
The Daimler ''Reitwagen'' ("riding car") or ''Einspur'' ("single track") was a motor vehicle made by Gottlieb Daimler and Wilhelm Maybach in 1885. It is widely recognized as the first motorcycle. Daimler is often called "the father of the motorcycle" for this invention. Even when the steam powered two-wheelers that preceded the ''Reitwagen'', the Michaux-Perreaux and Roper of 1867–1869, and the 1884 Copeland, are considered motorcycles, it remains nonetheless the first gasoline internal combustion motorcycle, and the forerunner of all vehicles, land, sea and air, that use its overwhelmingly popular engine type. First motorcycle? The ''Reitwagen''s status as the first motorcycle rests on whether the definition of motorcycle includes having an internal combustion engine. The ''Oxford English Dictionary'' uses this criterion. Even by that definition, the use of four wheels instead of two raises doubts. If the outriggers are accepted as auxiliary stabilizers, they point to a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brussels
Brussels (french: Bruxelles or ; nl, Brussel ), officially the Brussels-Capital Region (All text and all but one graphic show the English name as Brussels-Capital Region.) (french: link=no, Région de Bruxelles-Capitale; nl, link=no, Brussels Hoofdstedelijk Gewest), is a region of Belgium comprising 19 municipalities, including the City of Brussels, which is the capital of Belgium. The Brussels-Capital Region is located in the central portion of the country and is a part of both the French Community of Belgium and the Flemish Community, but is separate from the Flemish Region (within which it forms an enclave) and the Walloon Region. Brussels is the most densely populated region in Belgium, and although it has the highest GDP per capita, it has the lowest available income per household. The Brussels Region covers , a relatively small area compared to the two other regions, and has a population of over 1.2 million. The five times larger metropolitan area of Brussel ...

Production Vehicle
Production vehicles or production cars are mass-produced identical models, offered for sale to the public, and able to be legally driven on public roads ( street legal). Legislation and other rules further define the production vehicle within particular countries or uses. There is no single fixed global definition of the term. Origin In 1896 the term ''production car'' was used to describe a railway carriage that carried the scenery for an opera company. The earliest use of the term ''production car'' being applied to motor cars, found to date, was in a June 1914 American advertisement for a Regal motor car. The phrase was a shortened form of ''mass-produced'' or ''quantity-produced'' car. The phrase was also used in terms of the car to be made in production, as opposed to the prototype. At that time production cars referred to cheaper vehicles such as Model T's that were made in relatively large numbers on production lines, as opposed to the more expensive coach built models. ...

Gottlieb Daimler
Gottlieb Wilhelm Daimler (; 17 March 1834 – 6 March 1900) was a German engineer, industrial designer and industrialist born in Schorndorf ( Kingdom of Württemberg, a federal state of the German Confederation), in what is now Germany. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum-fueled engine. Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream. In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the ...

Model Year
The model year (sometimes abbreviated "MY") is a method of describing the version of a product which has been produced over multiple years. The model year may or may not be the same as the calendar year in which the product was manufactured. Automobiles United States and Canada Automobiles in the United States and Canada are identified and regulated by model year, whereas other markets use production date (month/year) to identify specific vehicles, and model codes in place of the "year" (model year) in the North American make-model-year identifier. In technical documents generated within the auto industry and its regulating agencies such as the U.S. National Highway Traffic Safety Administration and United States Environmental Protection Agency and Transport Canada and Environment Canada, the letters "MY" often precede the year (as in "MY2019" or "MY93"). Even without this prefix, however, in the North American context it is usually the model year rather than the vehic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorcycle Land-speed Record
The motorcycle land-speed record is the fastest speed achieved by a motorcycle on land. It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions. AMA National Land Speed Records requires 2 passes the same calendar day in opposite directions over a timed mile/kilo while FIM Land Speed World Records require two passes in opposite directions to be over a timed mile/kilo completed within 2 hours. These are special or modified motorcycles, distinct from the fastest production motorcycles. The first official Fédération Internationale de Motocyclisme (FIM) record was set in 1920, when Gene Walker rode an Indian on Daytona Beach at . Since late 2010, the Ack Attack team has held the motorcycle land speed record at .

Glenn Curtiss
Glenn Hammond Curtiss (May 21, 1878 – July 23, 1930) was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines. Curtiss won a race at the world's first international air meet in France and made the first long-distance flight in the U.S. His contributions in designing and building aircraft led to the formation of the Curtiss Aeroplane and Motor Company, which later merged into the Curtiss-Wright Corporation. His company built aircraft for the U.S. Army and Navy, and, during the years leading up to World War I, his experiments with seaplanes led to advances in naval aviation. Curtiss civil and military aircraft were so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
