Allen Norton (motorcycle)
Allen Norton is a defunct British company that supplied replicas of 350 and 500 cc Norton Manx road racing motorcycles. The company was run by Bernie Allen in Great Bedwyn, near Marlborough, Wiltshire. The company started to build replicas of the famous Norton Manx racers in 1990, based on the final 1961 Manx. Allen had been given the rights in 1989 after the death of Norton tuner Ray Petty and had received special permission to use the name "Norton" in England. Except for the magnetos, all the components used were of new manufacture. The engines were supplied by Summerfield Engineering of Derbyshire, the frames came from Goodman Engineering and were made from Reynolds 531 tubing. The machines were fitted with a 5-speed gearbox and a belt primary drive. (The originals used a 4-speed gearbox and chain primary drive.) Although the original Manx machines were pure racers, Allen fitted a speedometer, horn and brake light so the machines could be ridden on the road. The machines ...

Norton Manx
The Norton Manx or Manx Norton is a British racing motorcycle that was made from 1947 to 1962 by Norton Motors Ltd. Norton had contested every Isle of Man TT race from the inaugural 1907 event through into the 1970s, a feat unrivalled by any other manufacturer, and the development and honing of the Manx racing motorcycle was another step in this racing achievement. New Manx Nortons, built to various specifications are still available to buy new, from various suppliers around the world. These should not be confused with Norton production motorcycles even though they suit different categories and definitions of Classic Motorcycle Racing and Historic Motorcycle Racing in different countries around the world. Norton's first use of the name 'Manx' was applied to the 'Manx Grand Prix' model available from 1936-1940, a special racing version of their 'International' roadster, with telescopic forks and a plunger rear suspension, magnesium for the crankcases and cambox, and no provisi ...

Marlborough, Wiltshire
Marlborough ( , ) is a market town and Civil parishes in England, civil parish in the England, English Counties of England, county of Wiltshire on the A4 road (England), Old Bath Road, the old main road from London to Bath, Somerset, Bath. The town is on the River Kennet, 24 miles (39 km) north of Salisbury and 10 miles (16 km) southeast of Swindon. History The earliest sign of human habitation is the Marlborough Mound, a prehistoric tumulus in the grounds of Marlborough College. Recent radiocarbon dating has found it to date from about 2400 BC. It is of similar age to the larger Silbury Hill about west of the town. Legend has it that the Mound is the burial site of Merlin (wizard), Merlin and that the name of the town comes from Merlin's Tumulus, Barrow. More plausibly, the town's name possibly derives from the medieval term for chalky ground "marl"—thus, "town on chalk". However more recent research, from geographer John Everett-Heath, identifies the original O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton Motorcycle Company
The Norton Motorcycle Company (formerly Norton Motors, Ltd.) is a brand of motorcycles, originally based in Birmingham, England. For some years around 1990, the rights to use the name on motorcycles was owned by North American financiers. From 2008 to 2020, a line of motorcycles was produced under owner and chief executive Stuart Garner. Due to financial failure with large debts, in April 2020 administrators BDO agreed to sell certain aspects of Garner's business to Project 303 Bidco Limited, a new business established for the purpose with links to Indian motorcycle producer TVS Motor Company. The business was founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade".Holliday, Bob, ''Norton Story'', Patrick Stephens, 1972, p.11. By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignition Magneto
An ignition magneto, or high-tension magneto, is a magneto that provides current for the ignition system of a spark-ignition engine, such as a petrol engine. It produces pulses of high voltage for the spark plugs. The older term ''tension'' means ''voltage''. The use of ignition magnetos is now confined mainly to engines where there is no other available electrical supply, for example in lawnmowers and chainsaws. It is also widely used in aviation piston engines even though an electrical supply is usually available. In this case, the magneto's self-powered operation is considered to offer increased reliability; in theory, the magneto should continue operation as long as the engine is turning. History Firing the gap of a spark plug, particularly in the combustion chamber of a high-compression engine, requires a greater voltage (or ''higher tension'') than can be achieved by a simple magneto. The ''high-tension magneto'' combines an alternating current magneto generator a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derbyshire
Derbyshire ( ) is a ceremonial county in the East Midlands, England. It includes much of the Peak District National Park, the southern end of the Pennine range of hills and part of the National Forest. It borders Greater Manchester to the north-west, West Yorkshire to the north, South Yorkshire to the north-east, Nottinghamshire to the east, Leicestershire to the south-east, Staffordshire to the west and south-west and Cheshire to the west. Kinder Scout, at , is the highest point and Trent Meadows, where the River Trent leaves Derbyshire, the lowest at . The north–south River Derwent is the longest river at . In 2003, the Ordnance Survey named Church Flatts Farm at Coton in the Elms, near Swadlincote, as Britain's furthest point from the sea. Derby is a unitary authority area, but remains part of the ceremonial county. The county was a lot larger than its present coverage, it once extended to the boundaries of the City of Sheffield district in South Yorkshire where it cov ...

Gearbox
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belt Drive
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text the ''Dictionary of Local Expressions'' by the Han Dyna ...

Chain Drive
Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects. In other situations, a second gear is placed and the power is recovered by attaching shafts or hubs to this gear. Though drive chains are often simple oval loops, they can also go around corners by placi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
