Motorcycle Fork
A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp. The fork and its attachment points on the frame establish the critical geometric parameters of rake and trail, which play a major role in defining how a motorcycle handles and dives during braking. While the standard telescopic fork arrangement is found with few major differences among mainstream street motorcycles since the 1970s, historically there have been many variations, including trailin ...

IMZ-Ural
IMZ-Ural (russian: Ирбитский мотоциклетный завод, Irbitskiy Mototsikletniy Zavod, Irbit Motorcycle Factory) is a Russian maker of heavy sidecar motorcycles. In 1940, the Soviet Union acquired the design and production techniques for BMW R71 motorcycles and sidecars. The first M-72 model was finished in 1941. Originally, factories were to be located in Moscow, Leningrad (now Saint Petersburg), and Kharkiv, but due to the approach of Nazi German troops, the Moscow facilities were moved to Irbit, and the Leningrad and Kharkiv facilities to Gorkiy (now called Nizhny Novgorod). Plans for the M-72 were later sold to the Nanchang Aircraft Manufacturing Corporation, a Chinese industrial firm, to build the Chang Jiang. History The origins of the IMZ-Ural are linked to developments in the Eastern Front during World War II. The Soviet Union was preparing for possible military action by Nazi Germany. Joseph Stalin ordered the Soviet military to prepare in all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincent Motorcycles
Vincent Motorcycles was a British manufacturer of motorcycles from 1928 to 1955. The business was established by Philip Vincent who bought an existing manufacturing name HRD, initially renaming it as ''Vincent HRD'', producing his own motorcycles as HRD did previously with engines purchased as complete assemblies from other companies. From 1934, two new engines were developed as single cylinder in 500 cc and v-twin 1,000 cc capacities. Production grew from 1936, with the most-famous models being developed from the original designs after the War period in the late 1940s.''Classic Bike'', September 2002, ''The Vincent Story'' – Timeline, by ''Dave Minton'', pp.27–31 Accessed 17 September 2014 The 1948 Vincent Black Shadow was at the time the world's fastest production motorcycle. The name was changed to ''Vincent Engineers (Stevenage) Ltd.'' in 1952 after financial losses were experienced when releasing capital to produce a Vincent-engined prototype Indian (''Vindi ...

Douglas (motorcycles)
Douglas was a British motorcycle manufacturer from 1907–1957 based in Kingswood, Bristol, owned by the Douglas family, and especially known for its horizontally opposed twin cylinder engined bikes and as manufacturers of speedway machines. The company also built a range of cars between 1913 and 1922. History The brothers William and Edwin Douglas founded the Douglas Engineering Company in Bristol in 1882. Initially doing blacksmith work, they progressed to foundry work. Joseph F. Barter's Light Motors Ltd. was one of Douglas's customers. Barter built a single-cylinder bicycle engine between 1902 and 1904; he then developed the Fée bicycle engine system. The Fée's 200 cc flat-twin engine was mounted in-line with the frame, using chain drive to a countershaft beneath (with clutch); this then used a drive belt to power the bicycle's rear wheel. Barter founded Light Motors Ltd. to build the Fée system. Production began in 1905; the Fée's name was anglicized to Fairy sh ...

MV Agusta
MV Agusta (, full name: MV AGUSTA Motor S.p.A., original name: Meccanica Verghera Agusta or MV) is a motorcycle manufacturer founded by Count Domenico Agusta on 19 January 1945 as one of the branches of the Agusta aircraft company near Milan in Cascina Costa, Italy. The abbreviation MV stands for ''Meccanica'' (mechanics) ''Verghera'', the hamlet where the first MVs were made. The modern headquarters and main production facilities are located in Varese, Italy on the shore of Lake Varese. History 1943–1945: From idea to mass production It all began in the early years of the 20th century, when Count Giovanni Agusta left Sicily for northern Italy, where he built his first aircraft, the AG.1, four years after the Wright brothers had made history in the US. The First World War, which demonstrated the prospects of aviation, prompted the count to act decisively – and in 1923, in the town of Samarate, he founded the Costruzioni Aeronautiche Giovanni Agusta S.A.

Englishman
The English people are an ethnic group and nation native to England, who speak the English language, a West Germanic language, and share a common history and culture. The English identity is of Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Romans, and the partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al. Genomic signals of migration and continuity in Britain before the Anglo-Saxons. Nat Commun 7, 10326 (2016). https://doi.org/10.1038/ncomms10326 Collectively known as the Anglo-Saxons, they founded what was to become the Kingdom of England by th ...

Softail
A softail (shortened form of ''soft tail'') motorcycle intentionally looks like vintage motorcycles with a rigid hard-tail frame that has a triangle of steel tubes at the rear axle, like on a bicycle frame, but on a Softail these tubes are actually a triangular swingarm, with the shock absorber(s) hidden, as opposed to clearly visible regular twin shocks on both sides of the rear wheel on standard bikes. Since the introduction of the Harley-Davidson ''FXST Softail'' in 1983 as a registered trademark of the Motor Company, ''softail'' has become a genericized trademark for other models of cruiser motorcycles with Suspension (motorcycle)#Rear suspension, rear suspensions hidden for retro style reasons. This was done even though the rear wheel was often hidden behind bags or exhaust pipes. The hard tail becomes obsolete The first Suspension (motorcycle)#Rear suspension, rear suspensions on motorcycles were introduced before World War I, and many companies offered fully suspende ...

Chopper (motorcycle)
A chopper is a type of custom motorcycle which emerged in the US state of California in the late 1950s. A chopper employs radically modified steering angles and lengthened forks for a stretched-out appearance. They can be built from an original motorcycle which is modified ("chopped") or built from scratch. Some of the characteristic features of choppers are long front ends with extended forks often coupled with an increased rake angle, hardtail frames (frames without rear suspension), very tall "ape hanger" or very short "drag" handlebars, lengthened or stretched frames, and larger than stock front wheels. The "sissy bar", a set of tubes that connect the rear fender with the frame, and which are often extended several feet high, is a signature feature on many choppers. Two famous examples of the chopper are customised Harley-Davidsons, the "Captain America" and "Billy Bike", seen in the 1969 film ''Easy Rider''. History The Bob-Job Era, 1946–1959 Before there were chopper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
