Triumph Quadrant
The so-called Triumph Quadrant (aka "Quadrent") was a "bitsa" designed and built in secret by Doug Hele in 1973. It was a 1,000 cc four-cylinder motorcycle made up from Trident A trident is a three- pronged spear. It is used for spear fishing and historically as a polearm. The trident is the weapon of Poseidon, or Neptune, the God of the Sea in classical mythology. The trident may occasionally be held by other marine ... parts (although the camshaft was sourced from outside the factory). Essentially, the fourth cylinder came from grafting on an extra middle crankcase unit; but since the primary chaincase and final drive sprocket could not be relocated, the fourth cylinder protruded on the right hand side of the bike. The top speed was reputedly 125 mph. Quite why Hele developed this motorcycle is something of a mystery, as the lopsided machine could never have reached production to compete with modern Japanese machines such as the Honda CB750 or the Kawasak ...

Triumph Engineering
Triumph Engineering Co Ltd was a British motorcycle manufacturing company, based originally in Coventry and then in Meriden. A new company, Triumph Motorcycles Ltd, based in Hinckley, gained the name rights after the end of the company in the 1980s and is now one of the world's major motorcycle manufacturers. Origins The company was started by Siegfried Bettmann, who had emigrated from Nuremberg, part of the German Empire, to Coventry in England in 1883. In 1884, aged 20, Bettmann had founded his own company, the S. Bettmann & Co. Import Export Agency, in London. Bettmann's original products were bicycles, which the company bought and then sold under its own name. Bettmann also distributed sewing machines imported from Germany. In 1886, Bettmann sought a more specific name, and the company became known as the Triumph Cycle Company. A year later, the company was registered as the New Triumph Co. Ltd, now with funding from the Dunlop Pneumatic Tyre Company. During that year, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Types Of Motorcycles
The six main types of motorcycles are generally recognized as ''standard'', ''cruiser'', ''touring'', ''sports'', ''off-road'', and ''dual-purpose''. ''Sport touring'' is sometimes recognized as a seventh category or integrated with the ''touring'' category. Although there are many names and systems for classifying types of motorcycles based on their characteristics and usage, there are generally six categories recognized by most motorcycle manufacturers and organizations. Strong distinctions are usually made between the six main types of motorcycles and other motorcycles. Scooter, moped, underbone, miniature, pocket, electric, and three-wheeled motorcycles are generally excluded from the main categories but other classification schemes may include these as types of motorcycles. There is no universal system for classifying all types of motorcycles. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or legal definitions of a mot ...

Doug Hele
Douglas Lionel Hele (13 July 19193 November 2001) was a pioneering British motorcycle engineer with Triumph and other firms: BSA, Douglas and Norton. He was born in Birmingham in 1919 and died in Hagley, Worcestershire on 2 November 2001. Career Described as an 'outstanding student' at King's Norton Secondary School. Hele started his career in engineering as an apprentice with the Austin Motor Company at the Longbridge factory in Birmingham where he worked throughout the Second World War. He moved on to Douglas Motorcycles in Bristol in 1945 where he worked as a draughtsman in the motorcycle design team under former Norton chief designer Walter Moore. Moore encouraged him to go to the Norton factory, where he helped Polish engineer Leo Kusmicki design and develop the Featherbed framed Manx Norton single-cylinder racing models that won world championships in the early 1950s. After a short time at BSA where he worked on the 250cc single-cylinder racer with BSA chief ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-cylinder Engine
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets, turbofans, turboprops and turboshafts. Piston engines Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'. Engines with multiple banks are shorter than straight engines and can be designed to cancel out the unbalanced forces from each bank, in order to reduce the vibration. Most engines with f ...

BSA Rocket 3/Triumph Trident
The Triumph Trident and BSA Rocket 3 was a technically advanced, high-performance roadster (or standard) motorcycle made by Triumph Engineering and BSA (both companies part of the Birmingham Small Arms Company) from 1968 to 1975, and sold under both the Triumph and BSA marques. Alongside the Honda CB750, and later the Kawasaki triples, it brought a new level of sophistication to street motorcycles, marking the beginning of the superbike era. The Honda CB750 overshadowed the Trident to be remembered as the 'first superbike', in spite of the Triumph Trident actually debuting before the Honda by a few weeks. It had a , air-cooled OHV unit construction straight-three engine, with four gears and a conventional chassis and suspension. The engine had less vibration than the existing 360° twins. The Rocket 3/Trident was part of Triumph's plan to extend the model range beyond their 650 cc parallel twins. It was the last major motorcycle developed by Triumph at Meriden, West Mid ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
