A motorcycle (motorbike, bike, or, if three-wheeled, a trike) is a two or three-wheeled motor vehiclesteered by a handlebar from a saddle-style seat.[1][2][3]
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,[6] while 66.7 million cars were sold over the same period.[7]
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 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 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 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.[12][13]
Butler's Patent Velocycle
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.[14] 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.[15]
The Butler Petrol Cycle was a three-wheeled vehicle, with the rear wheel directly driven by a 5⁄8hp (0.47kW), 40cc (2.4cuin) displacement, 2+1⁄4in ×5in (57mm ×127mm) bore × stroke, flat twinfour-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 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 the front wheels. It was not, however, a success, as Butler failed to find sufficient financial backing.[16]
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.[17][18][19] Given the rapid rise in use of electric motorcycles worldwide,[20] defining only internal-combustion powered two-wheelers as 'motorcycles' is increasingly problematic. The first (petroleum fueled) internal-combustion motorcycles, like the German Reitwagen, were, however, also the first practical motorcycles.[18][21][22]
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,[12][13] constructed around the same time as the American Roper steam velocipede, built by Sylvester H. Roper of Roxbury, Massachusetts,[12][13] who had been demonstrating his machine at fairs and circuses in the eastern U.S. since 1867.[10] Roper built about 10 steam cars and cycles from the 1860s until his death in 1896.[19]
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. 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.
1902 Orient motocycle
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 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.[24]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,[25][26] producing over 20,000 bikes per year.[27]
During 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 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 499cc (30.5cuin) air-cooled four-stroke single-cylinder engine. It was also the first Triumph without pedals.[28][bettersourceneeded]
The Model H in particular, is regarded by many as having been the first "modern motorcycle".[29] Introduced in 1915 it had a 550cc 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".[30]
Postwar

By 1920, Harley-Davidson was the largest manufacturer,[31] with their motorcycles being sold by dealers in 67 countries.[32][33]
Amongst many British motorcycle manufacturers, Chater-Lea with its twin-cylinder models followed by its large singles in the 1920s stood out. Initially, using converted a Woodmann-designed OHV Blackburne engine it became the first 350 cc to exceed 100mph (160km/h), recording 100.81mph (162.24km/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 102.9mph (165.6km/h) for the firm. Chater-Lea produced variants of these world-beating sports models and became popular among racers at 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.[citation needed]
By the late 1920s or early 1930s, DKW in Germany took over as the largest manufacturer.[34][35][36]
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.[37] 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.[38]
Moto Guzzi produced competitive race machines, and until the end of 1957 had a succession of victories.[39] The following year, 1958, full enclosure fairings were banned from racing by 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 GermanMZs Walter Kaaden's engine work in the 1950s.[40]
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 300cc) motorcycles, mostly concentrated in Asian and African countries and produced in China and India.[citation needed] A Japanese example 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.[41] 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 8.5million to date.[42] Other major producers are Bajaj and TVS Motors.[43]

Technical aspects

Motorcycle construction 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 aluminiumframe, 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 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.
Fuel economy
Motorcycle fuel economy varies greatly with engine displacement and riding style.[44] A streamlined, fully faired Matzu Matsuzawa Honda XL125 achieved 470mpg‑US (0.50L/100km; 560mpg‑imp) in the Craig Vetter Fuel Economy Challenge "on real highways– in real conditions".[45] Due to low engine displacements (100–200cc (6.1–12.2cuin)), 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, the average motorcycle fuel economy is 44 miles per US gallon (19km per liter).[46]
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.[47]Fuel cells and petroleum-electric hybrids are also under development to extend the range and improve performance of the electric drive system.
Reliability
Water cooling and electronic control improve reliability than before (Triumph Bonneville 2017)
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.[48] 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.[48] There were not enough sport bikes in the survey for a statistically significant conclusion, though the data hinted at reliability as good as cruisers.[48] 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.[49] Trouble with fuel systems is often the result of improper winter storage, and brake problems may also be due to poor maintenance.[48] Of 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.[48] Harley-Davidsons had a rate of 24%, while BMWs did worse, with 30% of those needing major repairs.[48] There were not enough Triumph and Suzuki motorcycles surveyed for a statistically sound conclusion, though it appeared Suzukis were as reliable as the other three Japanese brands while Triumphs were comparable to Harley-Davidson and BMW.[48] 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.[48] 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 the same bike again, followed by 72% of Honda owners and 60 to 63% of Kawasaki and Yamaha owners.[48]
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 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.[50]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 the direction opposite of the desired turn. This practice is counterintuitive and therefore often confusing to novices– and even many experienced motorcyclists.[51][52][53]
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 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.
Records
The world record for the longest motorcycle jump was set in 2008 by Robbie Maddison with 107 metres (351ft).[54]
Wearing a motorcycle helmet (which is a legal requirement in many countries) reduces the risks of death or head injury in a motorcycle crash.
Motorcycles have a higher rate of fatal accidents than automobiles or trucks and buses. United States Department of Transportation data for 2005 from 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.[56] The same data shows that 1.56 fatalities occur per 100 million vehicle miles travelled for passenger cars, whereas for motorcycles the figure is 43.47 which is 28 times higher than for cars (37 times more deaths per mile travelled in 2007).[9] 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.[57] This is sometimes called a SMIDSY, an acronym formed from the motorists' common response of "Sorry mate, I didn't see you".[58] 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.[59]
The United Kingdom has several organisations dedicated to improving motorcycle safety by providing advanced rider training beyond what 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[60]

In South Africa, the Think Bike campaign is dedicated to increasing both motorcycle safety and 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.[61]
Motorcycle safety education is offered throughout 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 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 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.[67] 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).[68][69] The noise is caused by wind noise while riding, rolling noise from the tyres and the engine itself.[70] The helmet only provides insufficient protection against high sound pressure levels.[71] 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.
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.[72]
Sport– the rider leans forward into the wind and the weight of the upper torso is supported by the rider's core at low speed and air pressure at high speed.[73] The footpegs are below the rider or to the rear. The reduced frontal area cuts wind resistance and allows higher speeds. At low-speed in this position the rider's arms may bear some of the weight of the rider's torso, which can be problematic.
Standard– the rider sits upright or leans forward slightly. The feet are below the rider. These are motorcycles that are not specialised to one task, so they do not excel in any particular area.[74][75] The standard posture is used with touring and commuting as well as dirt and dual-sport bikes, and may offer advantages for beginners.[76]
Cruiser– the rider sits at a lower seat height with the upper torso upright or leaning slightly rearward. Legs are extended forwards, sometimes out of reach of the regular controls on cruiser pegs. The low seat height can be a consideration for new or short riders. Handlebars tend to be high and wide. 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 motorcycles can more readily accomplish.[77][78]
Factors of a motorcycle's ergonomic geometry that determine the seating posture include the height, angle and location of footpegs, seat and handlebars. Factors in a rider's physical geometry that contribute to seating posture include torso, arm, thigh and leg length, and overall rider height.
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. Most countries distinguish between mopeds of 49cc and the more powerful, larger vehicles, including scooter type motorcycles.[79] Many jurisdictions include some forms of three-wheeled cars as motorcycles.
In Nigeria, motorcycles, popularly referred to as Okada have been subject of many controversies with regards to safety and security followed by restriction of movement in many states. In 2020, it was banned in Lagos, Nigeria's most populous city.[80][81]
Environmental impact
Motorcycles and scooters' low fuel consumption has attracted interest in the United States from environmentalists and those affected by increased fuel prices.[82][83]Piaggio Group Americas supported this interest with the launch of a "Vespanomics" website and platform, claiming lower per-mile carbon emissions of 0.4lb/mile (113g/km) less than the average car, a 65% reduction, and better fuel economy.[84]
United States Environmental Protection Agency 2007 certification result reports for all vehicles versus on highway motorcycles (which also includes scooters),[86] 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. 54% of the tested 2007-model motorcycles were equipped with a catalytic converter.

European emission standards for motorcycles are similar to those for cars.[88] New motorcycles must meet Euro 5 standards,[89] while cars must meet Euro 6D-temp standards. Motorcycle emission controls are being updated and it has been proposed to update to Euro 5+ in 2024.[90]
Vietnam
According to the National Environmental Status Report 2016 and recent air quality reports, emissions from motor vehicles have been identified as the main cause of environmental pollution.[91][92] Among them, with over 68 million vehicles in operation nationwide (statistics from the Ministry of Transport, 2021), motorcycles are the largest source of pollutant emissions.[93][94][95]
In Hanoi, there are over 6 million motorcycles, of which nearly 3 million were manufactured before 2000.[96][97][98] In Ho Chi Minh City, there are about 7.8 million motorcycles, of which 67.89% are over 10 years old.[99][100] Air quality index (AQI) in urban centers often spikes during peak traffic times, such as rush hour in the morning and evening.[93][101][102]
A study by the Institute of Environment and Resources, Vietnam National University, Ho Chi Minh City, found that motorcycles account for about 29% of NO emissions, 90% of CO emissions, 65.4% of NMVOC emissions, 37.7% of particulate matter emissions, and 31% of fine particulate matter emissions.[93][103][104]
Traffic emissions account for 50% of total emissions in Ho Chi Minh City.[105] While the world is moving towards Euro 6 emission standards, most cars in Vietnam meet Euro 4 or Euro 5 standards. However, motorcycles still meet Euro 2 or Euro 3 standards, which were implemented over 25 years ago.[93]

A moped is a type of small motorcycle, generally having a less stringent licensing requirement than full motorcycles or automobiles. Historically, the term exclusively meant a similar vehicle with both bicycle pedals and a motorcycle engine. Mopeds typically travel only slightly faster than bicycles on public roads.
A feet first (FF) motorcycle is a class of motorcycle design which positions the rider with their feet ahead, like a car, rather than below and astride, as with conventional bikes. As there are other types of motorcycle that have a 'feet forward' position, an alternative term sometimes used is advanced single track vehicle. The name "feet first" was first used by Royce Creasey.
Suzuki Motor Corporation is a Japanese multinational mobility manufacturer headquartered in Hamamatsu, Shizuoka. It manufactures automobiles, motorcycles, all-terrain vehicles (ATVs), outboard marine engines, wheelchairs and a variety of other small internal combustion engines. In 2016, Suzuki was the eleventh biggest automaker by production worldwide. Suzuki has over 45,000 employees and has 35 production facilities in 23 countries, and 133 distributors in 192 countries. The worldwide sales volume of automobiles is the world's tenth largest, while domestic sales volume is the third largest in the country.
The Honda ST series, also known as the Pan-European in Europe, is a duo of Sport Touring motorcycles comprising the ST1100 and the later ST1300.
The Honda Super Cub is a Honda underbone motorcycle with a four-stroke single-cylinder engine ranging in displacement from 49 to 124 cc.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
In the market, there is a wide variety of types of motorcycles, each with unique characteristics and features. Models vary according to the specific needs of each user, such as standard, cruiser, touring, sports, off-road, dual-purpose, scooters, etc. Often, some types like sport touring are considered as an additional category or integrated with touring.
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above 52 km/h (32 mph); however, in recent years larger motors have been built, allowing bikes to reach speeds of upwards of 113 km/h.
Motorcycling is the act of riding a motorcycle. For some people, motorcycling may be the only affordable form of individual motorized transportation, and small-displacement motorcycles are the most common motor vehicle in the most populous countries, including India, China and Indonesia.
The BMW C1 is an enclosed scooter made by Bertone for BMW. Compared to a conventional scooter, the C1 offered extra safety features and protection from the elements. The rider would sit in a car-type seat and adopt a feet-forward posture. Introduced in 2000, it was available throughout Europe, but sales were disappointing and the C1 was discontinued in 2002. In 2009 the C1-E electric version was presented as a concept.
An underbone is a type of motorcycle that uses structural tube framing with an overlay of plastic or non-structural body panels and contrasts with monocoque or unibody designs where pressed steel serves both as the vehicle's structure and bodywork. Outside Asia, the term underbone is commonly misunderstood to refer to any lightweight motorcycle that uses the construction type, known colloquially as step-throughs, mopeds or scooters.
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Power is supplied by a rechargeable battery that drives one or more electric motors. Electric scooters are distinguished from motorcycles by having a step-through frame, instead of being straddled. Electric bicycles are similar vehicles, distinguished by retaining the ability to be propelled by the rider pedaling in addition to battery propulsion.
The history of the motorcycle begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel. Despite some early landmarks in its development, the motorcycle lacks a rigid pedigree that can be traced back to a single idea or machine. Instead, the idea seems to have occurred to numerous engineers and inventors around Europe at around the same time.
The Kawasaki Ninja ZX-9R is a motorcycle in the Ninja sport bike series from Japanese manufacturer Kawasaki, produced from 1994 until 2003. There were five model incarnations across two basic designs.
Motorcycle components and systems for a motorcycle are engineered, manufactured, and assembled in order to produce motorcycle models with the desired performance, aesthetics, and cost. The key components of modern motorcycles are presented below.
A scooter is a motorcycle with an underbone or step-through frame, a seat, a transmission that shifts without the operator having to operate a clutch lever, a platform for their feet, and with a method of operation that emphasizes comfort and fuel economy. Elements of scooter design were present in some of the earliest motorcycles, and motor scooters have been made since at least 1914. More recently, scooters have evolved to include scooters exceeding 250cc classified as Maxi-scooters.
The legal definition of a motorcycle for the purposes of registration, taxation and rider licensing in most countries is a powered two-wheel motor vehicle. Most countries distinguish between mopeds up to 49 cc and the more powerful, larger, vehicles known as motorcycles, including scooter type motorcycles. Many jurisdictions include some forms of three-wheelers as motorcycles.
Motorcycle testing and measurement includes a range of more than two dozen statistics giving the specifications of the motorcycle, and the actual performance, expressed by such things as the output of the engine, and the top speed or acceleration of the motorcycle. Most parameters are uncontroversial and claims made by manufacturers are generally accepted without verification.
