Alf Hagon
Alf Hagon (born 3 October 1931 in Ilford, England) is a former motorcycle speedway rider who later competed in Grasstrack. He manufactured off-road competition frames, forks and other components, later developing into the production of shock absorbers, specialising in modern-replicas of the traditional Girlings used as original equipment and replacements for historic motorcycles. Competition background Over a 12-year career in Speedway, he rode for six teams. In four consecutive years - 1961, 1962, 1963, and 1964 - he rode for teams that ended their seasons at the bottom of the table. He later found regular success when competing in Grasstrack. When riding in Grasstrack, Hagon started to develop a racing machine, with the assistance of Essex motorcycle dealer and competition sponsor Tom Kirby, creating a lightweight bike powered by a JAP engine. In 1958 he established a business building speedway and grasstrack bike frames in his mother's garden shed, but progress was int ...

English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common history and culture. The English identity is of History of Anglo-Saxon England, 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 Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al.

RAF Elvington
Royal Air Force Elvington or more simply RAF Elvington is a former Royal Air Force station which operated from the beginning of the Second World War until 1992 located at Elvington, Yorkshire, England. History Royal Air Force use The station was originally a grass airfield within No. 4 Group RAF. In the early 1940s the airfield was entirely reconstructed with three hardened runways replacing the grass. It re-opened in October 1942 as a station for 77 Squadron RAF and along with RAF Melbourne and RAF Pocklington was known as "No. 42 Base". The squadron had a strength of approximately 20 aircraft and initially used the twin engined Armstrong Whitworth Whitley medium bomber although this was quickly replaced by the Handley Page Halifax four engined heavy bomber which was being introduced. No. 77 Squadron suffered heavy losses during its time at Elvington with over 500 aircrew killed, missing or taken prisoner and almost 80 Halifaxes lost as it played a major part in the Battl ...

Duxford
Duxford is a village in Cambridgeshire, England, about south of Cambridge. It is part of the Hundred Parishes area. History The village formed on the banks of the River Cam, a little below its emergence from the hills of north Essex. One of the more populous settlements in its hundred it was split into two ecclesiastical parishes in medieval times until they were united in 1834. Originally known as ''Duxworth'' and listed as ''Dukeswrthe'' in the 10th century, and ''Dochesuuorde'' in the Domesday Book the village's name comes from "Worth (enclosure) of a man called Duc". Churches The village has two Grade I listed medieval parish churches, St John's Church and St Peter's Church. The two parishes were combined in 1874, services being held thereafter at St Peter's; St John's remained a chapel of ease and finally declared redundant. Still consecrated, it is now in the care of The Churches Conservation Trust. The churchyard has been cleared of headstones and is maintained by Duxf ...

V-Twin
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. Although widely associated with motorcycles (installed either transversely or longitudinally), V-twin engines have also been used for industrial engines and in several small cars. The V-twin design dates back to the late 1880s. Origins One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor. An early V-twin engined motorcycle was produced in November 1902 by the Princeps AutoCar Company in the United Kingdom. The following year, V-twin motorcycles were produced by Eclipse Motor & Cycle Co in the United Kingdom (the ''XL-ALL'' model), Glenn Curtiss in the United States, and NSU Motorenwerke in Germany. ...

Supercharged
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

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 ...

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 ...
