69-484: 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 . In 1966 AMC went bankrupt and were taken over by Manganese Bronze Holdings which formed Norton-Villiers to oversee operations. At

138-418: A manual five- or six-speed sequential transmission drives the swingarm -mounted rear wheel by a chain , driveshaft , or belt . The repair can be done using a Motorcycle lift . Motorcycle fuel economy varies greatly with engine displacement and riding style. A streamlined, fully faired Matzu Matsuzawa Honda XL125 achieved 470 mpg ‑US (0.50 L/100 km; 560 mpg ‑imp ) in

207-598: A 75.5 mm (3.0 in) bore x 78 mm (3.1 in) stroke, three valve head version of the AJS 7R making 36 bhp (27 kW). It was called the AJS 7R3, and was Ike's response to the Italian multi-cylinder racers. They did well enough in their first year, not as well the second. For 1954 Jack Williams, the works team manager, developed the bike further, lowering the engine in the frame, and making some tuning changes that gave 40 bhp (30 kW) @ 7800 rpm. It immediately won

276-559: A concept bike designated P10, and later Z26 as an improvement) that would separate the engine from the frame with rubber bushes, creating a more rider-friendly experience. The Norton Isolastic frame was developed in time for the 1967 Earls Court Show. Production began in April 1968, but bending problems with the frame resulted in a more-developed frame being introduced in January 1969. The Norton Commando promptly turned up in racing events, amongst

345-535: A cycle company in 1878. His sons Henry (Harry) and Charles (Charlie) joined him and the name was changed to H. Collier & Sons. 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

414-621: A financial rescue package contingent on a merger of the two groups and Norton-Villiers-Triumph was born. Motorcycle History (retrieved 21 October 2006) Associated Motorcycles 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

483-789: A full motorcycle licence or endorsement for completing a Motorcycle Safety course varies by province. Without the Motorcycle Safety Course the chance of getting insurance for the motorcycle is very low. The Canada Safety Council , a non-profit safety organisation, offers the Gearing Up program across Canada and is endorsed by the Motorcycle and Moped Industry Council. Training course graduates may qualify for reduced insurance premiums. Motorcyclists and motor scooter riders are also exposed to an increased risk of suffering hearing damage such as hearing loss and tinnitus (ringing ears). The noise

552-503: A higher load capacity roller bearing NJ306E made by FAG. The piston issues were resolved by removing the slot for oil drainage behind the oil ring, and drilling a series of holes instead, so that the piston crown didn't separate from the piston at higher RPMs . This brought a deterioration in finances. By the middle of 1972 the BSA group was in serious financial trouble as a result of its BSA and Triumph motorcycle activities. The government offered

621-555: A loss of £350,000. With the closure of the Norton plant at Birmingham in 1962 and the merger of Norton and Matchless production, the future was beginning to look rather bleak. In the sixties, with sales declining AMC made the commercial decision to focus on the Norton twins and the Matchless/AJS singles but they were not to be successful and the factory ceased production shortly afterwards. Some models were "parts bin specials" put together at

690-654: A motorcycle ( German : Motorrad ). Excelsior Motor Company , originally a bicycle manufacturing company based in Coventry , England , began production of their first motorcycle model in 1896. The first production motorcycle in the US was the Orient-Aster, built by Charles Metz in 1898 at his factory in Waltham, Massachusetts . In the early period of motorcycle history, many producers of bicycles adapted their designs to accommodate

759-414: A motorcycle either as OEM (factory-fitted) or aftermarket . Such accessories are selected by the owner to enhance the motorcycle's appearance, safety, performance, or comfort, and may include anything from mobile electronics to sidecars and trailers . Motorcycles have a higher rate of fatal accidents than automobiles or trucks and buses. United States Department of Transportation data for 2005 from

828-695: A new company, called Norton-Villiers in 1966. Some of the contents of the Norton factory including motorcycles were later auctioned off after the company went into receivership. Four-stroke scrambler production ceased in 1966. Matchless became overshadowed with focusing on BSA, Triumph and Norton from 1960. The more race-worthy Matchless G85CS replaced the G80CS having a purpose-built frame, alloy fuel tank, ultralight hubs, 12:1 compression ratio and GP Amal (carburettor) . Only 150 of these hand built bikes were made. Vic Eastwood, Chris Horsfield, and Dave Nicoll were signed to race these Matchless Motocross bikes. By

897-549: 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 activities 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

966-402: A role in how a motorcycle performs in given conditions. For example, one with a longer wheelbase provides the feeling of more stability by responding less to disturbances. Motorcycle tyres have a large influence over handling. Motorcycles must be leaned in order to make turns. This lean is induced by the method known as countersteering , in which the rider momentarily steers the handlebars in

1035-488: Is 43.47 which is 28 times higher than for cars (37 times more deaths per mile travelled in 2007). Furthermore, for motorcycles the accident rates have increased significantly since the end of the 1990s, while the rates have dropped for passenger cars. The most common configuration of motorcycle accidents in the United States is when a motorist pulls out or turns in front of a motorcyclist, violating their right-of-way. This

1104-439: Is caused by wind noise while riding, rolling noise from the tyres and the engine itself. The helmet only provides insufficient protection against high sound pressure levels. Medicine (as of 2024) is not able to cure hearing damage. Wearing hearing protection, such as special earplugs for motorcyclists, can help prevent hearing damage. The motorcyclist's riding position depends on rider body-geometry ( anthropometry ) combined with

1173-593: Is increasingly problematic. The first (petroleum fueled) internal-combustion motorcycles, like the German Reitwagen , were, however, also the first practical motorcycles. If a two-wheeled vehicle with steam propulsion is considered a motorcycle, then the first motorcycles built seem to be the French Michaux-Perreaux steam velocipede which patent application was filed in December 1868, constructed around

1242-610: Is necessary to pass the basic motorcycle licence test. These include the Institute of Advanced Motorists (IAM) and the Royal Society for the Prevention of Accidents (RoSPA). Along with increased personal safety, riders with these advanced qualifications may benefit from reduced insurance costs In South Africa, the Think Bike campaign is dedicated to increasing both motorcycle safety and

1311-493: Is often a racing counterpart to each type, such as road racing and street bikes, or motocross including dirt bikes. Street bikes include cruisers , sportbikes , scooters and mopeds , and many other types. Off-road motorcycles include many types designed for dirt-oriented racing classes such as motocross and are not street legal in most areas. Dual purpose machines like the dual-sport style are made to go off-road but include features to make them legal and comfortable on

1380-477: Is sometimes called a SMIDSY , an acronym formed from the motorists' common response of "Sorry mate, I didn't see you". Motorcyclists can anticipate and avoid some of these crashes with proper training, increasing their visibility to other traffic, keeping to the speed limits, and not consuming alcohol or other drugs before riding. The United Kingdom has several organisations dedicated to improving motorcycle safety by providing advanced rider training beyond what

1449-435: Is the 1958 Honda Super Cub , which went on to become the biggest selling vehicle of all time, with its 60 millionth unit produced in April 2008. Today, this area is dominated by mostly Indian companies with Hero MotoCorp emerging as the world's largest manufacturer of two wheelers. Its Splendor model has sold more than 8.5 million to date. Other major producers are Bajaj and TVS Motors . Motorcycle construction

1518-585: Is the engineering, manufacturing, and assembly of components and systems for a motorcycle which results in the performance, cost, and aesthetics desired by the designer. With some exceptions, construction of modern mass-produced motorcycles has standardised on a steel or aluminium frame , telescopic forks holding the front wheel, and disc brakes . Some other body parts, designed for either aesthetic or performance reasons may be added. A petrol-powered engine typically consisting of between one and four cylinders (and less commonly, up to eight cylinders) coupled to

1587-644: The Australian Capital Territory , Tasmania and the Northern Territory , it is compulsory to complete a basic rider training course before being issued a Learners Licence, after which they can ride on public roads. In Canada, motorcycle rider training is compulsory in Quebec and Manitoba only, but all provinces and territories have graduated licence programs which place restrictions on new drivers until they have gained experience. Eligibility for

1656-482: The Craig Vetter Fuel Economy Challenge "on real highways – in real conditions". Due to low engine displacements (100–200 cc (6.1–12.2 cu in)), and high power-to-mass ratios, motorcycles offer good fuel economy. Under conditions of fuel scarcity like 1950s Britain and modern developing nations, motorcycles claim large shares of the vehicle market. In the United States,

1725-705: The FIM in the light of the safety concerns. From the 1960s through the 1990s, small two-stroke motorcycles were popular worldwide, partly as a result of East German MZs Walter Kaaden's engine work in the 1950s. In the 21st century, the motorcycle industry is mainly dominated by Indian and Japanese motorcycle companies. In addition to the large capacity motorcycles, there is a large market in smaller capacity (less than 300 cc) motorcycles, mostly concentrated in Asian and African countries and produced in China and India. A Japanese example

1794-478: The Fatality Analysis Reporting System show that for passenger cars, 18.62 fatal crashes occur per 100,000 registered vehicles. For motorcycles this figure is higher at 75.19 per 100,000 registered vehicles – four times higher than for cars. The same data shows that 1.56 fatalities occur per 100 million vehicle miles travelled for passenger cars, whereas for motorcycles the figure

1863-645: The Ulster Grand Prix course at over 100 mph (161 km/h). It weighed 405 lb (184 kg). Its top speed was 135 mph (217 km/h). Then the Second World War intervened. During the War, Matchless manufactured 80,000 G3 and G3L models for the armed forces. AMC sold the Sunbeam name to BSA in 1943. Post-war landmarks start with the production of Matchless/AJS 350 cc and 500 cc singles, developed from

1932-615: The Wolverhampton plant and frames from the Manchester plant were assembled into complete machines, were presented with a Greater London Council compulsory purchase order . The Plumstead works closed in July 1969. A Government subsidy allowed assembly to move to a factory at North Way, Andover , with an aircraft hangar on nearby Thruxton Airfield housing the Test Department. Manufacturing

2001-496: The 1920s stood out. Initially, using converted a Woodmann-designed OHV Blackburne engine it became the first 350 cc to exceed 100 mph (160 km/h), recording 100.81 mph (162.24 km/h) over the flying kilometre during April 1924.[7] Later, Chater-Lea set a world record for the flying kilometre for 350 cc and 500 cc motorcycles at 102.9 mph (165.6 km/h) for the firm. Chater-Lea produced variants of these world-beating sports models and became popular among racers at

2070-501: The Brown family, now imports and retails small capacity motorcycles manufactured in China under the AJS name, whilst maintaining the spares supply for the Stormer models. Motorcycle A motorcycle ( motorbike , bike , or, if three-wheeled, a trike ) is a two or three-wheeled motor vehicle steered by a handlebar from a saddle-style seat. Motorcycle designs vary greatly to suit

2139-466: The First World War, motorbike production was greatly ramped up for the war effort to supply effective communications with front line troops. Messengers on horses were replaced with despatch riders on motorcycles carrying messages, performing reconnaissance and acting as a military police. American company Harley-Davidson was devoting over 50% of its factory output toward military contract by the end of

2208-521: The Isle of Man TT. Today, the firm is probably best remembered for its long-term contract to manufacture and supply AA Patrol motorcycles and sidecars. By the late 1920s or early 1930s, DKW in Germany took over as the largest manufacturer. In the 1950s, streamlining began to play an increasing part in the development of racing motorcycles and the "dustbin fairing" held out the possibility of radical changes to motorcycle design. NSU and Moto Guzzi were in

2277-581: The United States by organisations ranging from state agencies to non-profit organisations to corporations. Most states use the courses designed by the Motorcycle Safety Foundation (MSF), while Oregon and Idaho developed their own. All of the training programs include a Basic Rider Course, an Intermediate Rider Course and an Advanced Rider Course. In Ireland , since 2010, in the UK and some Australian jurisdictions, such as Victoria , New South Wales ,

2346-417: The art at the time. Starting was by compressed air. The engine was liquid-cooled, with a radiator over the rear driving wheel. Speed was controlled by means of a throttle valve lever. No braking system was fitted; the vehicle was stopped by raising and lowering the rear driving wheel using a foot-operated lever; the weight of the machine was then borne by two small castor wheels. The driver was seated between

2415-403: The average motorcycle fuel economy is 44 miles per US gallon (19 km per liter). Very high fuel economy equivalents are often derived by electric motorcycles. Electric motorcycles are nearly silent, zero-emission electric motor-driven vehicles. Operating range and top speed are limited by battery technology. Fuel cells and petroleum-electric hybrids are also under development to extend

2484-560: The awareness of motorcycles on the country's roads. The campaign, while strongest in the Gauteng province, has representation in Western Cape, KwaZulu Natal and the Free State. It has dozens of trained marshals available for various events such as cycle races and is deeply involved in numerous other projects such as the annual Motorcycle Toy Run. Motorcycle safety education is offered throughout

2553-514: The direction opposite of the desired turn. This practice is counterintuitive and therefore often confusing to novices – and even many experienced motorcyclists. With such short wheelbase , motorcycles can generate enough torque at the rear wheel, and enough stopping force at the front wheel, to lift the opposite wheel off the road. These actions, if performed on purpose, are known as wheelies and stoppies (or endos) respectively. Various features and accessories may be attached to

2622-474: The first "modern motorcycle". Introduced in 1915 it had a 550 cc side-valve four-stroke engine with a three-speed gearbox and belt transmission. It was so popular with its users that it was nicknamed the "Trusty Triumph". By 1920, Harley-Davidson was the largest manufacturer, with their motorcycles being sold by dealers in 67 countries. Amongst many British motorcycle manufacturers, Chater-Lea with its twin-cylinder models followed by its large singles in

2691-607: The first being London dealer Vincent Davey running a team under the Gus Kuhn name with riders Dave Croxford and Mick Andrew. The 1969 Commando S was introduced fitted with a high-level left-side exhaust and a 2.5-imperial-gallon (11 L) petrol tank, primarily aimed at the export (US) market. The original model was thereafter referred to as the Commando Fastback. In late 1968 the Plumstead works at Burrage Grove, where engines from

2760-488: The first series production motorcycle. Globally, motorcycles are comparable numerically to cars as a method of transport: in 2021, approximately 58.6 million new motorcycles were sold around the world, while 66.7 million cars were sold over the same period. In 2022, the top four motorcycle producers by volume and type were Honda , Yamaha , Kawasaki , and Suzuki . According to the US Department of Transportation ,

2829-464: The first two rounds of the World Championship and took first at the Isle of Man TT. These were factory specials, but one has survived, and a second has been reconstructed from spares. In 1953 there was a Clubman range of Matchless/AJS 350 cc and 500 cc singles, and the production model Matchless G45 500 twin became available. In 1952 further extended the empire by taking over Norton. Then 1958 saw

2898-429: The five brands with enough data to draw conclusions, Honda, Kawasaki and Yamaha were statistically tied, with 11 to 14% of those bikes in the survey experiencing major repairs. Harley-Davidsons had a rate of 24%, while BMWs did worse, with 30% of those needing major repairs. There were not enough Triumph and Suzuki motorcycles surveyed for a statistically sound conclusion, though it appeared Suzukis were as reliable as

2967-515: The front wheels. It was not, however, a success, as Butler failed to find sufficient financial backing. Many authorities have excluded steam powered , electric motorcycles or diesel-powered two-wheelers from the definition of a 'motorcycle', and credit the Daimler Reitwagen as the world's first motorcycle. Given the rapid rise in use of electric motorcycles worldwide, defining only internal-combustion powered two-wheelers as 'motorcycles'

3036-420: The introduction of unit construction 250 cc AJS/Matchless machines. From 1948, competition models of the singles were produced which gave the company some memorable wins. AMC withdrew from the world of works and one-off road racing at the end of the 1954, with the death of H.J.'Ike' Hatch, and in the face of fierce competition from the other European bikes. Instead of works specials, AJS and Norton would make

3105-453: The late 1960s, competition from Japan had driven the British motorcycle industry into a precipitous decline. In 1966 AMC collapsed and was reformed as Norton-Villiers under Manganese Bronze Holdings . This only staved off the problems for a little while and Norton-Villiers eventually went into liquidation in 1974. Norton was reformed with financial assistance from the British government as Norton-Villiers-Triumph (NVT) actually incorporating

3174-474: The legendary war-time Matchless G3 produced for the Army. In 1946 Freddie Clarke joined AMC as Chief Development Engineer after a row with his former employers, Triumph , and in 1947 AMC absorbed Francis-Barnett , followed later by the acquisition of James in 1951. In 1949 the first Matchless/AJS vertical twin (500cc) was produced, later to be joined by 600 cc and 650 cc vertical twins in 1956 and 1959 respectively. On

3243-498: The majority of BSAs motorcycle concerns but omitting the BSA name for Triumph. In part due to a labour dispute, NVT later went into receivership in 1974. Following the final collapse of NVT, the AJS name was bought by former works rider and competition manager Fluff Brown who continued production of the AJS Stormer in 250 and 360cc capacities. The company, AJS Motorcycles, still owned by

3312-555: The new internal combustion engine. As the engines became more powerful and designs outgrew the bicycle origins, the number of motorcycle producers increased. Many of the nineteenth-century inventors who worked on early motorcycles often moved on to other inventions. Daimler and Roper, for example, both went on to develop automobiles. At the end of the 19th century the first major mass-production firms were set up. In 1898, Triumph Motorcycles in England began producing motorbikes, and by 1903 it

3381-406: The number of fatalities per vehicle mile traveled was 37 times higher for motorcycles than for cars. The term motorcycle has different legal definitions depending on jurisdiction (see § Legal definitions and restrictions ). There are three major types of motorcycle: street, off-road, and dual purpose. Within these types, there are many sub-types of motorcycles for different purposes. There

3450-408: The other three Japanese brands while Triumphs were comparable to Harley-Davidson and BMW. Three-fourths of the repairs in the survey cost less than US$ 200 and two-thirds of the motorcycles were repaired in less than two days. In spite of their relatively worse reliability in this survey, Harley-Davidson and BMW owners showed the greatest owner satisfaction, and three-fourths of them said they would buy

3519-455: The press, along with quality control issues. The solution to the main bearing problems was the much-fabled bearings designated "Superblend" by Norton in a 1972 Service Release. These bearings were a 'special' with additional crowning, marked 6/MRJA30 and made by R&M (later RHP). Early in 1973 a superseding service release referred to Extra High Capacity Main Bearings. These were in reality just

3588-494: The production versions of the Manx Norton and the standard two valve AJS 7R, for privateers. In 1958 the Matchless/AJS road bikes were joined by a 250 cc and in 1960 by a 350 cc for a lightweight series of singles. In 1960 leading light Bert Hopwood resigned and joined Triumph at Meriden . That same year AMC posted a profit of a just over £200,000, not so good compared with BSA's £3.5 million. Then in 1961 they posted

3657-679: The racing front AMC were fielding the AJS Porcupine (500 cc forward-facing parallel twin), the AJS 7R (32 bhp, 350 cc OHC single), the Matchless G50 (a 500 cc variant of the 7R) and by 1951, the Matchless G45 (500 cc vertical twin). The AJS Porcupine had been designed for supercharging, before the rules changed ending supercharged racing motorcycles, but even so, Les Graham won the 1949 World Championship on an unsupercharged AJS 500 cc Porcupine. In 1951 AJS development engineer Ike Hatch developed

3726-579: The range and improve performance of the electric drive system. A 2013 survey of 4,424 readers of the US Consumer Reports magazine collected reliability data on 4,680 motorcycles purchased new from 2009 to 2012. The most common problem areas were accessories , brakes , electrical (including starters , charging , ignition ), and fuel systems , and the types of motorcycles with the greatest problems were touring, off-road/dual sport, sport-touring, and cruisers. There were not enough sport bikes in

3795-842: The request of the American dealers. The Americans were desert racing, so Berliners sent AMC an example custom bike using a Norton 750 motor in a G80CS frame, and asked them to build them some. This was the last Matchless motorcycle, the 748 cc G15 which was also sold as the AJS Model 33' and as the Norton P11. The G15 was produced up until 1969. A Mk2 version was sold in Britain from 1964. Matchless/AJS built predictable handling, comfortable, well-made, reliable and economical motorcycles, for their day. Unfortunately such attributes were not enough to keep them in business. Continuing poor sales led to AMC becoming part of

3864-400: The same bike again, followed by 72% of Honda owners and 60 to 63% of Kawasaki and Yamaha owners. Two-wheeled motorcycles stay upright while rolling due to a physical property known as conservation of angular momentum in the wheels. Angular momentum points along the axle, and it "wants" to stay pointing in that direction. Different types of motorcycles have different dynamics and these play

3933-466: The same time as the American Roper steam velocipede , built by Sylvester H. Roper of Roxbury, Massachusetts , who had been demonstrating his machine at fairs and circuses in the eastern U.S. since 1867. Roper built about 10 steam cars and cycles from the 1860s until his death in 1896. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle, and the first to be called

4002-621: The street as well. Each configuration offers either specialised advantage or broad capability, and each design creates a different riding posture. In some countries the use of pillions (rear seats) is restricted. The first internal combustion , petroleum fueled motorcycle was the Daimler Reitwagen . It was designed and built by the German inventors Gottlieb Daimler and Wilhelm Maybach in Bad Cannstatt , Germany, in 1885. This vehicle

4071-471: The survey for a statistically significant conclusion, though the data hinted at reliability as good as cruisers. These results may be partially explained by accessories including such equipment as fairings, luggage, and auxiliary lighting, which are frequently added to touring, adventure touring/dual sport and sport touring bikes. Trouble with fuel systems is often the result of improper winter storage, and brake problems may also be due to poor maintenance. Of

4140-415: 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

4209-462: The vanguard of this development, both producing very radical designs well ahead of their time. NSU produced the most advanced design, but after the deaths of four NSU riders in the 1954–1956 seasons, they abandoned further development and quit Grand Prix motorcycle racing . Moto Guzzi produced competitive race machines, and until the end of 1957 had a succession of victories. The following year, 1958, full enclosure fairings were banned from racing by

4278-449: The war. The British company Triumph Motorcycles sold more than 30,000 of its Triumph Type H model to allied forces during the war. With the rear wheel driven by a belt, the Model H was fitted with a 499 cc (30.5 cu in) air-cooled four-stroke single-cylinder engine. It was also the first Triumph without pedals . The Model H in particular, is regarded by many as having been

4347-535: Was a completely new development for 1967 and was further developed for 1968–69. The P11 was available either as Norton or Matchless. For Norton-Villiers the development of a new engine to market was cost-prohibitive, but the vibration of the 750 cc vertical twin was so well transmitted to the rider through the Featherbed frame of the Norton Atlas , that it was dropped in favour of an earlier experimental frame (based on

4416-481: Was a three-wheeled vehicle, with the rear wheel directly driven by a 5 ⁄ 8  hp (0.47 kW), 40 cc (2.4 cu in) displacement, 2 + 1 ⁄ 4  in × 5 in (57 mm × 127 mm) bore × stroke, flat twin four-stroke engine (with magneto ignition replaced by coil and battery) equipped with rotary valves and a float-fed carburettor (five years before Maybach ) and Ackermann steering , all of which were state of

4485-527: Was concentrated at Wolverhampton, in the former Villiers factory, with 80 complete machines produced there each week. Wolverhampton also shipped components, assembled engines, and gearboxes to the Andover assembly line. The high performance Combat engine gave 65 bhp (48 kW) at 6,500 rpm using 10 :1 compression ratio. It was too much for the stretched old 1948 Model 7 497 cc-based design, with main bearing failures and broken pistons being reported in

4554-803: Was designed as an expedient testbed for their new engine, rather than a true prototype vehicle. The first commercial design for a self-propelled cycle was a three-wheel design called the Butler Petrol Cycle, conceived of Edward Butler in England in 1884. He exhibited his plans for the vehicle at the Stanley Cycle Show in London in 1884. The vehicle was built by the Merryweather Fire Engine company in Greenwich , in 1888. The Butler Petrol Cycle

4623-410: 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. In 1939 a 495 cc AJS V4 was built to compete against the supercharged BMWs then dominating racing. The bike was a water-cooled and supercharged design. In 1939 the dry-sump V4 was the first bike to lap

4692-447: Was producing over 500 bikes. Other British firms were Royal Enfield , Norton , Douglas Motorcycles and Birmingham Small Arms Company who began motorbike production in 1899, 1902, 1907 and 1910, respectively. Indian began production in 1901 and Harley-Davidson was established two years later. By the outbreak of World War I, the largest motorcycle manufacturer in the world was Indian, producing over 20,000 bikes per year. During

4761-464: Was unlike either the safety bicycles or the boneshaker bicycles of the era in that it had zero degrees of steering axis angle and no fork offset , and thus did not use the principles of bicycle and motorcycle dynamics developed nearly 70 years earlier. Instead, it relied on two outrigger wheels to remain upright while turning. The inventors called their invention the Reitwagen ("riding car"). It
