BMW R50
The R60 and R60/2 are 600 cc boxer-twin that were manufactured from 1956 to 1969 in Munich, Germany, by BMW. Production history Some 20,133 of these 600 cc shaft-drive, opposed twin R60 (1956–1960, ), R60/2 (1960–1969, ), and R60US (1968–1969, 30 hp) were built. These models, except for those with the "US" designation, were designed primarily as rugged motorcycles to pull sidecars (mounting points were built in) and had duplex tubular steel frames. Simultaneously manufactured were related models, including the 500 cc R50 (1955–1960, ), the R50/2 (1960–1969, 26 hp), the R50 S (1960–1962, ), the R50US (1968–1969, 26 hp), and the 600 cc sport-oriented R69 (1955–1960, 35 hp), R69S (1960–1969, ), and R69US (1968–1969, 42 hp). In the United States, all these Earles-fork and US-fork (i.e., telescopic fork) models from 1955 to 1969 are often lumped together as "Slash-2" BMWs, even though that is technically incorrec ...

Flat-twin Engine
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the ''Lanchester 8 hp Phaeton'' car released in 1900. The flat-twin engine was used in several other cars since, however a more common usage is in motorcycles; early models oriented the cylinders in line with the frame, however later models switched to the cylinders being perpendicular to the frame to provide even cooling across both cylinders. Flat-twin engines were also used in several aircraft up until the 1930s and in various stationary applications from the 1930s to the 1960s. The Australian lawnmower manufacturer Victa also produced a flat-twin engine push mower from August 1975 to 1980 dubbed as the ‘Twin 500’ and â ...

Motorcycle Handlebar
A motorcycle handlebar is a tubular component of a motorcycle's steering mechanism. Handlebars provide a mounting place for controls such as brake, throttle, clutch, horn, light switches and rear view mirrors; and they help to support part of the rider's weight. Even when a handlebar is a single piece it is usually referred to in the plural as handlebars. Construction Handlebars are made from round-section metal tubing, typically aluminium alloys or chrome plated steel but also of carbon fibre and titanium, shaped to the desired contour. Holes may be drilled for the internal routing of control cables such as brake, throttle, and clutch. Risers hold the handlebars above their mounting position on the upper triple clamp or the top of the fork, and may be integrated into the bar itself or separate items. Each handlebar end may contain bar-end weights to damp vibration by isolating the bar's resonant frequency from that of the engine. Electrically heated grips may be fitted to pr ...

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] |
BMW Motorcycles
BMW Motorrad is the motorcycle brand of BMW, part of its Corporate and Brand Development division. It has produced motorcycles since 1923, and achieved record sales for the fifth year in succession in 2015. With a total of 136,963 vehicles sold in 2015, BMW registered a growth of 10.9% in sales in comparison with 2014. In May 2011, the 2,000,000th motorcycle produced by BMW Motorrad was an R1200GS. History The company began as an aircraft engine manufacturer in the early 20th century and through World War I. BMW manufactured its first motorcycle in 1923, the R32, which featured a flat-twin boxer engine. BMW Motorrad still uses the flat-twin boxer configuration, but now manufactures motorcycles with a variety of engine configurations. Current production With the exception of the G310 series (which is produced at TVS's Tamil Nadu, India plant), all BMW Motorrad's motorcycle production takes place at its plant in Berlin, Germany.

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 ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Hella Signal
''Hella'' is an American slang term that originated in the San Francisco Bay Area. It is used as an intensifying adverb such as in "hella bad" or "hella good" and was eventually added to the ''Oxford English Dictionary'' in 2002. It is possibly a contraction of the phrase "hell of a" or "hell of a lot f, in turn reduced to "hell of", though some scholars doubt this etymology since its grammatical usage does not align with those phrases. It often appears in place of the words "really", "a lot", "totally", "very", and in some cases, "yes". Whereas ''hell of a'' is generally used with a noun, according to linguist Pamela Munro, ''hella'' is primarily used to modify an adjective such as "good". According to lexicographer Allan A. Metcalf, the word is a marker of northern California dialect. According to Colleen Cotter, "Southern Californians know the term ... but rarely use it." Sometimes the term ''grippa'' is used to mock "NorCal" dialect, with the actual meaning being the oppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touring Motorcycle
A touring motorcycle is a type of motorcycle designed for touring. Although almost any motorcycle can be used for this purpose, manufacturers have developed specific models designed to address the particular needs of these riders. Touring motorcycles commonly have large displacement fairings and windshields that offer a high degree of weather and wind protection, large-capacity fuel tanks for long ranges between fill-ups, engines with a great deal of low-end horsepower, and a more relaxed, upright seating position than sport bikes. Particularly in the US, touring motorcycles may be given names such as ''bagger'', ''full bagger'', ''full dresser'', ''full dress tourer'', or ''dresser''. These monikers (often used disparagingly or jocularly) originally applied to cruisers with full sets of saddlebags or panniers such as Harley-Davidsons; but these terms may now refer to any touring motorcycle. Full-dress tourers Full-dress touring motorcycles are generally characterized by ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Bar On A BMW R60-2 Motorcycle
Safety is the state of being "safe", the condition of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk. Meanings There are two slightly different meanings of ''safety''. For example, ''home safety'' may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants. Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers unfortunately are left to conclude whether they comprise a redundancy. This confuses the uniqueness that should be reserved for each by itself. When seen as unique, as we intend here, each term will a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
