Norton Model 88 Dominator
The Norton Model 88 Dominator, also originally known as the ''Dominator De Luxe'' was a 500 cc vertical twin motorcycle manufactured by the British Norton Motorcycle Company from 1952 to 1966. It was the first of Norton's motorcycles to use the featherbed frame, which established Norton's reputation of producing fine handling machines. The 88 used the Bert Hopwood designed engine that was first fitted to the Model 7 and was initially for export only. It became available on the home market in 1953. Norton were a small manufacturer at the time and without the economies of scale the model was expensive compared to other manufacturer's equivalent machines. The 88 retailed for 20% more than the contemporary Triumph Speed Twin and was dearer than the 650 cc Triumph Thunderbird. Technical details Engine and transmission The 497 cc Bert Hopwood designed engine from the Model 7 was used in the 88. The pre-unit 360° pushrod vertical twin used cast iron cylinders and head.

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 Global, 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 motor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triumph Speed Twin
The Speed Twin 5T is a standard motorcycle that was made by Triumph at their Coventry, and later Meriden factories. Edward Turner, Triumph’s Chief Designer and Managing Director, launched the Triumph Speed Twin at the 1937 National Motorcycle Show. It was a 500 cc OHV vertical twin in a lightweight frame and the first truly successful British parallel twin, setting the standard for many twins to follow. After World War II the Speed Twin was responsible for the survival of Triumph - and every major British marque offered a 500 cc twin designed on similar lines to the Speed Twin. History Edward Turner’s Triumph twin was a major turning point for the British motorcycle industry, as although a 500 cc parallel twin of medium capacity was not revolutionary, the 5T Speed Twin model was lighter than many contemporary singles with significantly more power and torque. Early models were only available in 'Amaranth red' with hand painted gold pinstripes to set off the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescopic Fork
A telescopic fork is a form of motorcycle front suspension whose use is so common that it is virtually universal. The telescopic fork uses fork tubes and sliders which contain the springs and dampers. The main advantages of the telescopic fork are that (i) it is simple in design and relatively cheap to manufacture and assemble; (ii) it is lighter than older designs using external components and linkage systems; and (iii) it has a clean and simple appearance that bikers find attractive. Telescopic forks sometimes have gaiters to protect the fork tubes from abrasion and corrosion. A more modern (and more expensive) version of the conventional telescopic fork is the inverted or "USD" (upside-down) fork. BMW's patented telelever front suspension appears at first glance to be conventional telescopic fork, but the fork tubes contain neither springs nor damping. Instead, a wishbone and an inboard monoshock perform suspension duties, and the forks serve to locate the front wheel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton ES2
The Norton ES2 is a Norton motorcycle produced from 1927 until 1964. From 1965, a different machine was produced for a short time by parent manufacturer AMC, based on a Matchless but badged as Norton ES2 Mk2. Development It was a long stroke single, always 79mm x 100mm bore and stroke, originally launched as a sports motorcycle but throughout its long life it was gradually overtaken by more powerful models. It remained popular due to its reliability and ease of maintenance, as well as the traditional design. From 1947 the ES2 had an innovative hydraulically damped telescopic front fork and race developed rear plunger suspension. From 1953 it had a single downtube swinging-arm frame. Featherbed frame From 1959 it used the Rex McCandless designed Featherbed frame, with upgrades featuring an improved AMC gearbox, revised cylinder head, crankshaft-mounted Lucas RM15 60-watt alternator with coil ignition and an 8-inch front brake with full width hubs front and rear.The Moto ...

Reynolds 531
Reynolds 531 (pronounced 'five-three-one') is a brand name, registered to Reynolds Technology of Birmingham in the United Kingdom, for a manganese–molybdenum, medium-carbon steel tubing that was used in many quality applications, including race car chassis, aircraft components and, most famously, bicycle frame tubing. It is one of a number of tubing types developed by Reynolds. Reynolds 531 "was the standard of excellence for many decades" among bicycle frame-building materials. And because of the availability of a wide range of butting, diameters and thicknesses of tubes, along with different stays and fork blades, it became the tubing of choice for most frame builders. Details Introduced in 1935 and for many years at the forefront of alloy steel tubing technology, 531 cycle tubing has been superseded by more complex alloys and heat-treatment/ cold-forming cycles as Reynolds continues to compete with other manufacturers of steel for the bicycle industry.Reynolds Technolog ...

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 provis ...

Rex McCandless
Rex McCandless (1915–1992) was a former motorcycle racer, designer and constructor from Northern Ireland. Born in Hillsborough, County Down, McCandless had been a successful motorcycle racer prior to the Second World War. During the war, he worked in the aviation industry. He had been working as a vehicle mechanic when in 1943, he went into business with his brother Cromie McCandless to repair vehicles for the Ministry of Supply. It was at this time that he built his own motorcycle which became the prototype for the successful featherbed frame adapted by the Norton Motorcycle Company. In the following years McCandless worked on the frame design, improving it and calling it the 'Kneeler'. This version went on to break many world speed records. In the mid-1950s he moved into four wheels and he designed two aluminum-bodied racing cars for Harry Ferguson. In the 1960s he turned his attention to aviation and built his own autogyro An autogyro (from Greek and , "self-tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Dynamo
"Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via solid state technology) is effective and usually economical. History Induction with permanent magnets The Faraday disk was the first electric generator. The horseshoe-shaped magnet ''(A)'' created a magnetic field through the disk ''(D)''. When the disk was turned, this induced an elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Block
In an internal combustion engine, the engine block is the structure which contains the cylinders and other components. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block", although technically, the block of a modern engine (i.e. multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each of these elements, which were bolted together during engine assembly. ...
