This compares to around 590 million cars, or about 91 per 1000 people. Most of the motorcycles, 58%, are in the developing countries of Asia—Southern and Eastern Asia, and the Asia Pacific countries, excluding Japan—while 33% of the cars (195 million) are concentrated in the United States and Japan. As of 2002, in the two countries of India and China, there were a total of only 15 million cars,[7] but 71 million motorcycles.[8]

History

Replica of the Daimler-Maybach Reitwagen
A 1913 Fabrique National in-line four with shaft drive from Belgium
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 in 1885.[9] This vehicle was unlike either the safety bicycles and boneshaker bicycles of the era in that it had zero degrees of steering axis angle and no fork offset, and thus not using the principles of bicycle and motorcycle dynamics developed 30 years earlier.^ That means it was built just five years after Francesco Laverda decided to create a lightweight motorcycle for his own use.

^ And this machine is an original condition, original paint example.From the Bonhams press release:"The Hildebrand brothers, Henry and Wilhelm, developed their motorcycle in… .

^ English interior designer, Barrend Massow built a panther shaped motorcycle.

Instead, it relied on two outrigger wheels to remain upright while turning.[10] The inventors called their invention the Reitwagen ("riding car"). It was designed as an expedient testbed for their new engine, rather than a true prototype vehicle.[11][12] .Many authorities define motorcycle this way, excluding steam engined as well as electric and diesel two-wheelers, and thus give credit the Daimler Reitwagen as the world's first motorcycle.^ Harry Hurt, one of the world's foremost authorities on motorcycle crashes and their causes, has died.

^ His groundbreaking research published in 1981 continues to form the basis of many of the country's motorcycle safety programs and is credited with saving countless lives.

^ This is the first of a series of Field Tests in which we'll give real riders real riding gear and have them tell us how it works in the real world.

[13][14]
.If a two-wheeled vehicle with steam propulsion is considered a motorcycle, then the first was the French Michaux-Perreaux steam bicycle of 1868.[11][12] This was followed by the American Roper steam velocipede of 1869.[11][12] One such machine was demonstrated at fairs and circuses in the eastern U.S. in 1867, built by Sylvester Howard Roper of Roxbury, Massachusetts.^ It is one of the first production motorcycles ever made.

^ Two Wheel Terrors 2 is stuffed with cool motorcycles covering everything, I think, except crotch rockets and big touring bikes.

^ I had always considered the Pulsar 200 to be one of the most propotionate and good looking motorcycle to have graced our Indian roads.

[9]
A pre-war Polish Sokół 1000
.In 1894, Hildebrand & Wolfmüller became the first series production motorcycle, and the first to be called, in German, a motorrad, that is, a motorcycle.^ It is one of the first production motorcycles ever made.

^ It's quite rare for any pre-1900 motorcycle to come up for sale, but the Hildebrand & Wolfmüller is the granddaddy of our whole two-wheeled family, the first machine to be called explicitly a motorcycle ('motorrad' auf Deutsche), and the first in any reasonable series production.

^ You are looking at an original circa 1895 Hildebrand & Wolfmüller motorcycle and Bonhams will auction it in Stafford, England on April 25th, 2010.

[11][12][15] In the early period of motorcycle history, many producers of bicycles adapted their designs to accommodate the new internal combustion engine. .As the engines became more powerful and designs outgrew the bicycle origins, the number of motorcycle producers increased.^ All high powered single engine propeller planes, especially with large blades, have swing effect when you increase power suddenly.

NSU Sportmax streamlined motorcycle, 250 cc class winner of the 1955 Grand Prix season
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 the vanguard of this development both producing very radical designs well ahead of their time.[24] 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.[25] Moto-Guzzi produced competitive race machines, and by 1957 nearly all the Grand Prix races were being won by streamlined machines.[citation needed] The following year, 1958, full enclosure fairings were banned from racing by the FIM in the light of the safety concerns.

Technical aspects

A Suzuki GS500 with a clearly visible frame (painted silver).

Construction

Motorcycle construction is the engineering, manufacturing, and assembly of components and systems for a motorcycle which results in 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.^ It’s good having a friend in the machine shop business, because he came through for me with some wonderful custom brackets that would attach to the front brake calipers.

^ Unlike the Hyper-lite brake lights, the front running lights weren’t so simple to install: the wiring was more involved and I needed to make some brackets because the lights were going to be mounted low on the forks.

^ This will be the 3rd time in a month (front wheel replacement, and fork bearing adjustment).

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 a manual five- or six-speed sequential transmission drives the swingarm-mounted rear wheel by a chain, driveshaft or belt.^ Me 109 G: "Landing: landing glide using engine power and the following light wheel touchdown was easy and non-problematic.

Fuel economy

.Motorcycle fuel economy varies greatly with engine displacement and riding style[30] ranging from a low of 29 mpg-US (8.1 L/100 km; 35 mpg-imp) reported by a Honda VTR1000F rider,[31] to 107 mpg-US (2.20 L/100 km; 129 mpg-imp) reported for the Verucci Nitro 50 cc Scooter.^ This was preceded by elevator buffet and opening the slats about 20 mph (30 km/h) above the stall, these being accompanied by the unpleasant aileron snatching as the slats opened unevenly.

[32] A specially designed Matzu Matsuzawa Honda XL125 achieved 470 mpg-US (0.50 L/100 km; 560 mpg-imp) "on real highways - in real conditions."[33] .Due to lower engine displacements (100 cc–200 cc), motorcycles in developing countries offer good fuel economy.^ C3 fuel was equivalent to 100/145 grade fuel by Allied standards, which is remarkably good.
  • virtualpilots.fi: 109myths 13 January 2010 20:49 UTC www.virtualpilots.fi [Source type: FILTERED WITH BAYES]

[citation needed] In the Indian market, the second most selling company, Bajaj, offers two models with superior fuel economy: XCD 125 and Platina. Both are 125 cc motorbikes with a company-claimed fuel economy of 256 mpg-US (0.919 L/100 km; 307 mpg-imp) and 261 mpg-US (0.901 L/100 km; 313 mpg-imp), respectively.[citation needed]

Electric motorcycles

Dynamics

Racing motorcycles leaning in a turn.
.Different types of motorcycles have different dynamics and these play a role in how a motorcycle performs in given conditions.^ Other types, including the British, French, American and Italian planes, different often wildly from their "paper performance".
  • virtualpilots.fi: 109myths 13 January 2010 20:49 UTC www.virtualpilots.fi [Source type: FILTERED WITH BAYES]

For example, a longer wheelbase provides more stability in a straight line.[34] Motorcycle tyres have a large influence over handling.
.Motorcycles must be leaned in order to make turns.^ Youths charged in theft of motorcycleAuburn CitizenThe APD said it recovered the stolen motorcycle, which had been painted in order to make identifying it more difficult.

This lean is induced by the method known as countersteering, in which the rider steers the handlebars in the direction opposite of the desired turn. .Because it is counter-intuitive this practice is often very confusing to novices—and even to many experienced motorcyclists.^ Indeed many fresh young pilots thought they were pulling very tight turns even when the slats were still closed against the wing.

These actions, if performed on purpose, are known as wheelies and stoppies respectively. If carried past the point of recovery the resulting upset is known as an "endo" (short for "end-over-end"), or "looping" the vehicle.

Accessories

Various features and accessories may be attached to a motorcycle either as OEM (factory-fitted) or after-market. .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.^ Irvine, California (January 7, 2010) - The California Highway Patrol selected the Motorcycle Safety Foundation to administer the California Motorcyclist Safety Program (CMSP) for the fourth consecutive time.

Social aspects

Popularity

Motorbikes are the primary form of transportation in Vietnam.
In numerous cultures, motorcycles are the primary means of motorised transport. .According to the Taiwanese government, for example, "the number of automobiles per ten thousand population is around 2,500, and the number of motorcycles is about 5,000."[36] In places such as Vietnam, motorcycle use is extremely high due to a lack of public transport and low income levels that put automobiles out of reach for many.^ When put into a full throttle climb at low air speeds, the airplane climbed at a very steep angle, and our fighters used to have difficulty in keeping their sights on the enemy even when at such a height that their rates of climb were comparible.

[3] In Vietnam, motorised traffic consist of mostly motorbikes.[4] The four largest motorcycle markets in the world are all in Asia: China, India, Indonesia, and Vietnam.[3] The motorcycle is also popular in Brazil's frontier towns.[5] Amid the global economic downturn of 2008, the motorcycle market grew by 6.5%.[37]
Recent years have seen an increase in the popularity of motorcycles elsewhere. .In the USA, registrations increased by 51% between 2000 and 2005.[38] This is mainly attributed to increasing fuel prices and urban congestion,[39] but is also partly due to television programmes such as reality show American Chopper, or adventure-travel shows such as Long Way Down.^ C3 fuel was used like water/methanol to cool down the mixture so that you can increase the pressure in the cylinders.

Subcultures

Around the world, motorcycles have historically been associated with subcultures. Some of these subcultures have been loose-knit social groups such as the cafe racers of 1950s Britain, and the Mods and Rockers of the 1960s. A few are believed to be criminal gangs.
Social motorcyclist organisations are popular and are sometimes organised geographically, focus on individual makes, or even specific models. Example motorcycle clubs include: American Motorcyclist Association, Harley Owners Group and BMW MOA. .Some organisations hold large international motorcycle rallies in different parts of the world that are attended by many thousands of riders.^ Motorcycle show at DC convention centerWashington ExaminerAP WASHINGTON — The Washington convention center is hosting the Cycle World International Motorcycle Show with displays of new motorcycles and custom bikes.

.Whereas many social motorcycle organisations raise money for charities through organised events and rides, some other motorcycle organisations exist only for the direct benefit of others.^ Stacey and I were planning a ride out to the coast for a BMWRO event this weekend, but I caught some evil respiratory infection, probably during the plane ride back from Colorado.

^ In the spirit of winter, here are some videos I found on YouTube that show motorcycles and snow can exist harmoniously!

^ Harley-Davidson Garage Party events provide a fun, social environment for women to learn about the sport of motorcycling, as well as meet other women who are interested in riding.

Bikers Against Child Abuse (BACA) is one example. BACA assigns members to individual children to help them through difficult situations, or even stay with the child if the child is alone or frightened.[40]
In recent decades, motorcyclists have formed political lobbying organisations in order to influence legislators to introduce motorcycle-friendly legislation. One of the oldest such organisations, the British Motorcycle Action Group, was founded in 1973 specifically in response to helmet compulsion, introduced without public consultation.[41] In addition, the British Motorcyclists Federation (BMF), originally founded in 1960 as a reaction to the public perception of motorcyclists as leather-jacketed hooligans, has itself moved into political lobbying. .Likewise, the U.S. has ABATE, which, like most such organisations, also works to improve motorcycle safety, as well as running the usual charity fund-raising events and rallies, often for motorcycle-related political interests.^ Not all of his work is based around motorcycles; he does incredible portraiture as well, and other genres.Mark Mederski,… .

At the other end of the spectrum from the charitable organizations and the motorcycle rights activists are the Outlaw Motorcycle Gangs. These are defined by the Provincial Court of Manitoba as: "Any group of motorcycle enthusiasts who have voluntarily made a commitment to band together and abide by their organizations' rigorous rules enforced by violence, who engage in activities that bring them and their club into serious conflict with society and the law".[43] The Federal Bureau of Investigation (FBI) and Criminal Intelligence Service Canada have designated four MCs as Outlaw Motorcycle Gangs (OMGs), which are the Pagans, Hells Angels, Outlaws MC, and Bandidos,[44][45] known as the "Big Four".[46]

[48] In places where it is permitted, lane splitting, also known as filtering, allows motorcycles to use the space between vehicles to move through stationary or slow traffic.[49]
In the UK, motorcycles are exempt from the £8 per day London congestion charge other vehicles must pay to enter the city during the day. Motorcycles are also exempt from toll charges at some river crossings, such as the Severn Bridge, Dartford Crossing, and Mersey Tunnels. Some cities, such as Bristol, allow motorcycles to use bus lanes and provide dedicated free parking. In the United States, those states that have high-occupancy vehicle lanes also allow for motorcycle travel in them. Other countries have similar policies.
In Australia many toll roads are free of tolls for motorcycles, and in some Australian cities (e.g. Melbourne) motorcycles can be parked on footpaths, allowing motorcyclists to park easily in the centre in of the central business district.[citation needed]
.In New Zealand motorcycle riders are not required to pay for parking that is controlled by a barrier arm;[50] the arm does not occupy the entire width of the lane, and the motorcyclist simply rides around it.^ Dixie Rider National Motorcycle News announced today that the publication will change its name to U.S. RiderNews with the January 2005 issue.

Each configuration offers either specialised advantage or broad capability, and each design creates a different riding posture.

Motorcycle rider postures

The motorcyclist's riding position depends on rider body-geometry (anthropometry) combined with the geometry of the motorcycle itself. These factors create a set of three basic postures.[60]
.
  • Sport — the rider leans forwards into the wind and the weight of the upper torso is supported by air pressure as long as the motorcycle is travelling at speed, typically above 50 mph (80 km/h).^ At speeds above 100 mph, the pilot has the impression of diving, and below 80 mph one of sinking.
    • virtualpilots.fi: 109myths 13 January 2010 20:49 UTC www.virtualpilots.fi [Source type: FILTERED WITH BAYES]

    ^ When you sit on a sport bike you’ll be tilted forward with your feet back behind your seat and some of your weight resting on your wrists.

    ^ So down we went about 2,000 feet with the air speed indicator amusing itself by adding a lot of big numbers - to a little over 400 mph.
    • virtualpilots.fi: 109myths 13 January 2010 20:49 UTC www.virtualpilots.fi [Source type: FILTERED WITH BAYES]

    The footpegs are below the rider or to the rear. The reduced frontal area cuts wind resistance and allow higher speeds. However, at low-speed this position throws the weight of the rider onto the arms instead, and this is quickly tiring to the wrists of unfamiliar riders. .Moreover, the sports position makes it more difficult for the rider to look around and foot through traffic.^ Youths charged in theft of motorcycleAuburn CitizenThe APD said it recovered the stolen motorcycle, which had been painted in order to make identifying it more difficult.

    ^ You’ll have to lift your head up to look around, because the sitting position forces you to curl into the shape of the bike.

    ^ Forward view can only be described as apalling, and due to the tail/brake arrangement this makes weaving more difficult than on other similar types.
    • virtualpilots.fi: 109myths 13 January 2010 20:49 UTC www.virtualpilots.fi [Source type: FILTERED WITH BAYES]

    .Many sport bikes have narrow, swept-back handlebars, or clip-ons (short stubs clamped to the telescopic fork tubes).^ When you sit on a sport bike you’ll be tilted forward with your feet back behind your seat and some of your weight resting on your wrists.

    .Following the style of racing bikes, most have full-fairings and often come with almost complete engine enclosure, although motorcycles with a sport riding position are becoming more diverse with the marketing of factory naked bikes, streetfighters, retro cafe racers, and other blends of styles, having varying riding positions somewhere in the range from sport to standard.^ Zoom.Sport bikes are made for racing.

    ^ This is a basic bike that comes fairly “naked” with an exposed engine and higher ground clearance (and therefore seat height), so you can jump logs or curbs and ford streams or ditches.

    ^ By 1952, Laverda had created a factory team of four racing bikes to enter into the Milano-Taranta road race—and when all four bikes finished the race, the Laverda name was… .

    [61]
  • Standard — the rider sits upright or leans forwards slightly. The feet are below the rider, not too far to the front or back. .These are straightforward, versatile motorcycles that are not too specialized for one task, but don't excel in one area either.^ And in our modern motorcycle kingdom one genus has evolved to best tackle this task – the Sport Tourers.

    ^ I don't usually comment much on the motorcycle news stuff, there are other blogs that specialize in that so why duplicate the effort?

    [62] Standards are used in touring, commuting, and sporting, and are good for beginners.[61] .The rider enjoys the benefits of freedom of head movement, good visibility in all directions, and easier use of the feet while moving through stationary traffic.
  • Cruiser — the rider sits at a lower seat height with the upper torso upright or leaning slightly rearwards.^ We used to fire all guns when in good position.

    Legs are extended forwards, sometimes out of reach of the regular controls on cruiser pegs. .The low seat heights can be a consideration for new or short riders.^ The French data is for an early-type DB601A with low full throttle height, while at the time of the Battle of Britain, the new type with increased full throttle height and accordingly increased top speed was available.
    • virtualpilots.fi: 109myths 13 January 2010 20:49 UTC www.virtualpilots.fi [Source type: FILTERED WITH BAYES]

    Handlebars tend to be high, and wide. Harley-Davidsons are exemplars of this style.[63] .The emphasis is on comfort, while compromising cornering ability because of low ground clearance and the greater likelihood of scraping foot pegs, floor boards, or other parts if turns are taken at the speeds other types of motorcycles can do.^ A bolt had fallen out and the peg swung down towards the ground with a couple inches of clearance.

    [64][65]
Important factors of a motorcycle's ergonomic geometry that determine the seating posture include the height, angle and location of footpegs, seat and handlebars. Likewise, factors in a rider's physical geometry that contribute to seating posture include torso, arm, thigh and leg length, and overall rider height.

Legal definitions and restrictions

.A motorcycle is broadly defined by law in most countries for the purposes of registration, taxation and rider licensing as a powered two-wheel motor vehicle.^ Two Wheel Terrors 2 is stuffed with cool motorcycles covering everything, I think, except crotch rockets and big touring bikes.

^ Powerful naked bikes have nearly become a two-wheeled cliché, but Aprilia’s Tuono 1000R Factory offers a visually arresting departure from the crowd.

Environmental impact

In 2007 and 2008, motorcycles and scooters, due to good fuel efficiency, attracted interest in the United States from environmentalists and those affected by increased fuel prices.[66][67] .Piaggio Group Americas supported this interest with the launch of a "Vespanomics" website and platform, citing lower per-mile carbon emissions of 0.4 lb/mile (113 g/km) less than the average car, a 65% reduction, and better fuel economy.^ ON.

.Other sources, however, claim that while motorcycles produce much less pollution in terms of greenhouse gases, a motorcycle can in some cases emit 10–20 times the quantity of nitrogen oxides (NOx) when compared to the NOx emissions of a car.^ G series were much better on this regard compared to 109 E, which yet again wasn't such a dog as many claim.

Along with other technologies that have taken longer to appear in motorcycles (e.g. fuel injection, anti-lock brake systems),[citation needed] catalytic converters are becoming increasingly commonplace.
.United States Environmental Protection Agency 2007 certification result reports for all vehicles versus on highway motorcycles (which also includes scooters),[70] the average certified emissions level for 12,327 vehicles tested was 0.734. The average "Nox+Co End-Of-Useful-Life-Emissions" for 3,863 motorcycles tested was 0.8531, for a difference of about 16%, not the claimed 10X factor.^ Claims of continuing growth in both the United States as well as Canada were made by the British motorcycle manufacturer adn the trade advocacy group, the Motorcycle Industry Council (MIC).

Simple English

A motorcycle (or motorbike) is a form of transport to move people from one place to another. It does not have 4 wheels like a car. It has 2 wheels like a bicycle. But it has a motor like a car. A motorcycle is normally driven by one person. One may also take another person with him, on the back of the motorcycle. There are also motorcycles with a sidecar, then 3 people can be transported.

Motorcycles are used both for transportation and extreme sports. Since motorcycles can be lighter than cars, they can accelerate more quickly. But it also makes them not as safe as cars, because they do not have a protecting chassis around them like cars. Very often motorcycle-riders are injured heavily in accidents. A motorcycle rider can wear a helmet and clothing that has armor. This special clothing may reduce the rider's injuries in an accident.

In the middle of the last century, motorcycles were used by many as a cheap method of transportation. Many people who did not have the money to buy a car, could afford a small motorcycle. Back then motorcycles were also much slower and with less motor-power. Today, motorcycles are used more as a hobby. Unlike cars, motorcycles do not have a protection against wind and rain. That makes it difficult to drive in winter or at bad weather.

On-road bikes (ones that are allowed on public roads) must have a special type of driver's license to be ridden legally. Off-road bikes are not allowed to be driven on public roads.

Speed and stunts are the main goals for off-road bike sports. Many on-road bikes are much faster than off-road bikes and can be used in sports such as motorbike racing.

There are different manufacturers of motorcycle, like Honda, Suzuki, Yamaha. A well known American manufacturer of motorcycles is Harley-Davidson.
