BMW R69
The R69S, R69US, and R69 are motorcycles, fitted with 594 cc boxer twin engines, that were manufactured by BMW in Munich, Germany. Production history From 1955 to 1969, 15,347 of these 594 cc shaft-drive, opposed twin motorcycles were built. The R69 was produced from 1955 to 1960, the R69S was produced from 1960 to 1969, and the 42 hp R69US was produced from 1968 to 1969. These models were designed as relatively high powered, high compression sport bikes, although the Earles fork R69 and R69S came with sidecar lugs installed on the frames. These lugs were deleted from the telescopic fork "US" models. The low compression R60/2, produced from 1955 to 1960, was designed primarily for sidecar use, though it was popularly used as a solo bike, along with the 30 hp R60US, which was produced between 1968 and 1969. The sport-oriented R69S, R69US, and R69 succeeded the plunger-framed 1951 to 1955 R68, which had an engine very similar to that in the later R ...

Motorcycles Powered By Flat Engines
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17%) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of BMW Motorcycles
BMW's motorcycle history began in 1921 when the company commenced manufacturing engines for other companies. BMW's own motorcycles—sold under the BMW Motorrad brand—began in 1923 with the BMW R 32, which was powered by a flat-twin engine (also called a "boxer-twin" engine). Production of motorcycles with flat-twin engines continues to this day, however BMW has also produced many models with other types of engines. Motorcycle history 1921–1938 At the end of World War I, the Treaty of Versailles demanded that BMW cease production of aircraft engines. To remain in business, the company began producing small industrial engines (along with farm equipment, household items and railway brakes). In 1920, BMW M2B15 flat-twin petrol engine was released. Despite being designed as a portable industrial engine, the M2B15 was also used by several motorcycle manufacturers, including for the 1920–1923 Victoria KR1 and the 1920–1922 Bayerische Flugzeugwerke (BFw) ''Helios'' motorcyc ...

Kawasaki Z1
The Kawasaki Z1 is a four-cylinder, air-cooled, double-overhead camshaft, carbureted, chain-drive motorcycle introduced in 1972 by Kawasaki. Following the introduction of Honda's CB750 in 1968, the Z1 helped popularize the in-line, across-the-frame four-cylinder, a format that became known as the ''Universal Japanese Motorcycle'' or ''UJM.'' The Z1 was noted for being the first large-capacity Japanese four-cylinder motorcycle to use the double-overhead-camshaft system on a production motorcycle. When it was introduced, only the MV Agusta 750 S used this system; it was a very expensive limited-production machine, as opposed to the Kawasaki which was less than half the price. Marketed variously as the Z1-900, 900 Z1 or 900 S4 ("Super Four"), the Z1 was the first of Kawasaki's Z models. History The Kawasaki Z1 was developed under the project name "New York Steak". In the late 1960s Kawasaki, already an established manufacturer of two-stroke motorcycles, had begun prototyping a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Final Drive Ratio
A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. Features of gears and gear trains include: * The gear ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set. * A planetary gear train provides high gear reduction in a compact package. * It is possible to design gear teeth for gears that are non-circular, yet still transmit torque smoothly. * The speed ratios of chain and belt drives are computed in the same way as gear ratios. See bicycle gearing. The transmission of rotation between contacting toothed wheels can be traced back to the Antikythera mechanism of Greece and the south-pointing chariot of China. Illustrations by the Renaissance scientist Georgius Agricola show gear trains with c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autodrome De Linas-Montlhéry
Autodrome de Montlhéry (established 4 October 1924) is a motor racing circuit, officially called L’autodrome de Linas-Montlhéry, owned by Utac, located south-west of the small town of Montlhéry about south of Paris. History Industrialist Alexandre Lamblin hired René Jamin to design the oval shaped track for up to vehicles at . It was initially called Autodrome Parisien, and had especially high banking. A road circuit was added in 1925. The first race there, the 1925 French Grand Prix, was held on 26 July 1925 and organised by The Automobile Club de France Grand Prix. It was a race in which Robert Benoist in a Delage won; Antonio Ascari died in an Alfa Romeo P2. The Grand Prix revisited the track in 1927 and each year between 1931 and 1937. In 1939 the track was sold to the government, deprived of maintenance, and again sold to ''Union technique de l’automobile et du cycle'' (UTAC) in December 1946. The last certification for racing was gained in 2001. Motorcar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW /5 Motorcycles
''For the WWII-era motorcycle, see BMW R75'' The BMW R50/5, R60/5, and R75/5 form a range of boxer twin motorcycles manufactured in Berlin, Germany, by BMW for model years 1970-1973 and featuring electric starting and telescopic forks. History For the 1970 model year, BMW launched three new models having engine capacities of 500 cc (R50/5), 600 cc (R60/5), and 750 cc (R75/5). The R75/5 could reach 110 mph (177 km/h). Model year 1972 saw the introduction of the rectangular tank with chrome side panels. For the second half of the 1973 model year, BMW lengthened the rear swingarm 2.5 inch (6.4 cm), resulting in the “long-wheelbase” (LWB) models. This enabled a larger battery, while retaining the kick starter. The /5 series was the first series to be manufactured completely in Berlin, as by 1969 all of Munich's production capacity was needed for automobiles. "Berlin with its well-trained workforce was an obvious choice. So in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
