Norton P11
The Norton P11 is a air-cooled OHV parallel twin motorcycle that was made by Norton-Villiers from 1967 to 1969. Designed as an extremely light high power-to-weight ratio desert racer, P11 was revised in 1968 to the P11A and marketed as the Norton Ranger, a road legal version of the P11 with a more comfortable seat to make it suitable for normal road use. The Norton P11 gained a reputation as a ' desert racer' in the late 1960s but by 1969 lighter two stroke desert racers began to dominate the sport and the Norton had begun Commando production and it was selling well. Norton ended production of the P11 series to concentrate on the Commando, which used a number of ideas developed on the P11 series. Development Norton-Villiers developed the P11 from the Norton Atlas and Norton/Matchless N15CS and G15CS models as an export model for the growing sport of desert racing. Prototyped by Californian Norton Distributor Bob Blair using the Atlas ''750 cc'' twin cylinder engine in a Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton-Villiers
Norton-Villiers was a British motorcycle manufacturer formed in the 1960s following the collapse of AMC. With the general decline of the British motorcycle industry, under a British Government initiative it was later combined with the remnants of BSA Triumph to form Norton-Villiers-Triumph. Norton Villiers (1966–1973) In 1966 AMC went bankrupt and were taken over by Manganese Bronze Holdings which formed Norton-Villiers to oversee operations. At the time Norton was the only motorcycle marque in the company that was making money. The AJS and Matchless traditional single cylinder four-stroke models were finished. Matchless and AJS badged models, with Norton motors, were assembled till 1969. In 1968 all models had new carburettors, ignition systems and an ignition lock. The G15CS, N15CS and M33CS had improved cycle parts for 1968–69. The P11 series was a completely new development for 1967 and was further developed for 1968–69. The P11 was available either as Norton or Mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton Atlas
The Norton Atlas was a Norton motorcycle made between 1962 and 1968, until it was replaced by the Norton Commando. Development The Mark 1 Atlas was launched as the 750SS in the early 1960s, but by the time it appeared c. 1962 it was being called a 750cc Atlas, with Norton's famous Featherbed frame. Designer Bert Hopwood’s 1949 497cc Dominator engine had been bored and stroked over the years to 745cc, via 600cc and then 650cc versions, to appeal to the American market and initially was only produced for export. ''Motorcycle Mechanics'', May 1962, p.13 ''Looking Ahead - Mighty Atlas. "...this exciting 750 cc twin from Norton's.'' ic''Unfortunately, as yet, it is only for the American market, to compete against their hefty capacity bikes.''". Accessed and added 2014-09-20 The styling was aimed at the US market with high-rise handlebars, small 2.5-gallon petrol tank and valanced chrome mudguards and chain guard. The look was completed with a heavy-duty WM3-18 rear wheel, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-twin Engine
A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, Jet Skis, all-terrain vehicles, tractors and ultralight aircraft. Various different crankshaft configurations have been used for straight-twin engines, with the most common being 360 degrees, 180 degrees and 270 degrees. Terminology The straight-twin layout is also referred to as "parallel-twin", "vertical-twin" and "inline-twin". Some of these terms originally had specific meanings relating to the crankshaft angle or engine orientation, however they are often also used interchangeably. In the United Kingdom, the term "parallel-twin" is traditionally used for engines with a crankshaft angle of 360 degrees, since the two pistons are in the same direction (i.e. parallel to each o ...

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert Racing
Desert racing is the act of racing through the desert in a two- or four-wheeled off-road vehicle. Races, which generally consist of two or more loops around a course covering up to , can take the form of Hare and Hound or Hare scramble style events, and are often laid out over a long and harsh track through relatively barren terrain. Point-to-point–style races, including the famous Mint 400 and Baja 1000, attract nationally ranked and celebrity drivers. This type of racing tests the endurance and capabilities of racer and machine, and while organized clubs or teams sometimes field multiple sponsored riders for particular events, desert racing in its purest form is largely an individual endeavor. Winning racers accrue points to advance their rank and placement in future contests. Desert racing vehicles, which include rugged enduro-style motorcycle, four wheeled all-terrain vehicles, trucks (like Group T4), pickup trucks (like Trophy Trucks), and dune buggies, have specialized ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Norton Commando
The Norton Commando is a British Norton-Villiers motorcycle with an OHV pre-unit parallel-twin engine, produced by the Norton Motorcycle company from 1967 until 1977. Initially having a nominal ''750 cc'' displacement, actually , in 1973 it became an ''850 cc'', actually . It had a hemi-type head, similar to all OHV Norton engines since the early 1920s. During its ten years of production, the Commando was popular all over the world. In the United Kingdom it won the ''Motor Cycle News'' "Machine of the Year" award for five successive years from 1968 to 1972. Around 60,000 Commandos were made in total. Background Associated Motor Cycles (AMC), Norton's parent company, had become bankrupt in 1966 and had been purchased by Manganese Bronze Holdings, who already owned Villiers Engineering, forming Norton-Villiers. Chairman Dennis Poore saw the need to produce a new flagship motorcycle to replace the aging 750 cc Atlas, the engine design of which could be traced bac ...

Associated Motor Cycles
Associated Motor Cycles (AMC) was a British motorcycle manufacturer founded by the Collier brothers as a parent company for the Matchless and AJS motorcycle companies. It later absorbed Francis-Barnett, James, and Norton before incorporation into Norton-Villiers. Henry Herbert Collier founded Matchless as a cycle company in 1878. His sons Henry (Harry) and Charles (Charlie) joined him and the name was changed to H. Collier & Sons. History AJS had been bought by Matchless's owners, the Colliers, in 1931 and Sunbeam was added in 1937 from Imperial Chemical Industries. The name of the Matchless Motor Cycles company was changed to "Amalgamated Motor Cycles Ltd" in 1937 and "Associated Motor Cycles (AMC)" in 1938. AMC was not a manufacturer in its own right, but rather the parent company of a group of motorcycle manufacturers which included Matchless, AJS, Norton, James, Francis-Barnett, Sunbeam and others.
