The ATV is commonly called a quad (quad-bike) in Australia, New Zealand and the United Kingdom. They are used extensively in agriculture because of their speed and light footprint on the soil.

The term "All-Terrain Vehicle" or ATV in North America (quad-bike or quad elsewhere) is used in a general sense to describe any of a number of small open motorized buggies and tricycles designed for off-road use. A dune buggy is a recreational Vehicle with large Wheels and wide Tires designed for use on sand Dunes or Beaches The design A tricycle (often abbreviated to trike) is a three-wheeled vehicle Off Roading is a term for driving a specialized vehicle on unpaved roads such as Sand, Gravel, riverbeds Mud, Snow, Rocks, However, the American National Standards Institute (ANSI) defines an ATV as a vehicle that travels on low pressure tires, with a seat that is straddled by the operator, and with handlebars for steering control. Handlebars usually refer to the steering mechanism for Bicycles Motorcycles ATVs Snowmobiles and personal watercraft; the equivalent Although it is street legal in some countries, it is not in California and some states within the United States. By the current ANSI definition it is intended for use by a single operator, although a change to include 2-seaters (in tandem) is under consideration. ^[1]

The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slow speeds. MotorCycle is the title of a 1993 album by Rock band Daniel Amos, released on BAI Records. Although typically equipped with three or four wheels, six-wheel models exist for specialized applications. Engine sizes of ATVs currently for sale in the United States (as of 2008 products) range from 49 cc to 950 cc.

Development

Honda Quad ATV. () is a Multinational corporation, engine Manufacturer and engineering corporation headquartered in Japan.

Early days

Royal Enfield built and put on sale a powered Quadracycle in 1893 that works in the same way as, and resembles, a modern quad-bike. See also Royal Enfield Motors Royal Enfield was the brand of the Enfield Cycle Company an English Engineering company. The advent of the automobile replaced the Quadracycle (Powered or otherwise).

ATVs were made in the United States a decade before 3- and 4-wheeled vehicles were introduced by Honda and other Japanese companies. During the 1960s numerous manufacturers offered similar small off-road vehicles that were designed to float and were capable of traversing swamps, ponds and streams, as well as dry land. Typically constructed from a hard plastic or fiberglass "tub", they usually had six wheels—all driven—with low pressure (around 3 PSI) balloon tires, no suspension (other than what the tires offered) and skid-steer steering. These early amphibious models were the original all-terrain vehicles—or ATVs. Contrary to today's ANSI definition of an ATV, they were intended for multiple riders sitting inside, and would usually have a steering wheel or control stick rather than motorcycle-type handle bars as stipulated in the current definition.

Since the advent of three- and four-wheeled, straddled ATVs, these have more or less 'taken over' the term, leaving aside the 6x6 and 8x8 floating variety now mostly known as AATVs (Amphibious All-Terrain Vehicles). Small off-road and typically Six-wheel drive, Amphibious vehicles were developed in the early 1960s and quickly became popular in both the US and Canada

Three wheelers

Honda made the first three-wheeled ATVs in 1970, which were famously portrayed in the James Bond movie, Diamonds Are Forever. James Bond 007 is a Fictional character created in 1953 by writer Ian Fleming, who featured him in twelve Novels and two Short story Diamonds Are Forever (1971 is the seventh Spy film of the British James Bond series and the sixth to star Sean Connery Dubbed the US90 and later—when Honda acquired the trademark on the term^[2]—the ATC90, it was designed purely for recreational use. () is a Multinational corporation, engine Manufacturer and engineering corporation headquartered in Japan. Clearly influenced by earlier ATVs, it featured large balloon tires instead of a mechanical suspension. ^[3]

By the early 1980s, suspension and lower-profile tires were introduced. The 1982 Honda ATC200E Big Red was a landmark model. It featured both suspension and racks, making it the first utility three-wheeled ATV. The ability to go anywhere on terrain that most other vehicles could not cross soon made them popular with US and Canadian hunters, and those just looking for a good trail ride. Soon other manufacturers introduced their own models.

Sport models were also developed by Honda, which had a virtual monopoly in the market due to effective patents on design and engine placement. The 1981 ATC250R was the first high-performance three-wheeler, featuring full suspension, a 248 cc two-stroke motor, a five-speed transmission with manual clutch and a front disc brake. For the sporting trail rider, the 1983 ATC200X was another landmark machine. It has an easy-to-handle 192 cc four-stroke that was ideal for new participants in the sport.

Over the next few years all manufacturers, except Suzuki, developed high performance two-stroke engined machines to compete against Honda's monopoly, in the market, but did not sell as many due to the reputation already secured by Honda. These models were the Yamaha Tri-Z YTZ250 with a 246 cc two-stroke engine a manual clutch and 5- or 6-speed gearbox, and the Kawasaki Tecate KXT250 with a 249 cc two-stroke with 5-speed gearbox and a manual clutch. Other smaller or lesser known companies such as Tiger ATV, Can Am, Franks and Cagiva produced racing three wheelers, but in much smaller numbers.

Bombardier Recreational Products or BRP is a Canadian company Cagiva is an Italian Motorcycle manufacturer It was founded in 1950 by Giovanni Castiglioni in Varese, originally producing small metal components Few of these machines are known to exist today and are highly sought by collectors.

Four wheelers

Suzuki was a leader in the development of 4-wheeled ATVs. is a Multinational corporation headquartered in Hamamatsu Japan that specializes in manufacturing compact automobiles a full range of Motorcycles All-Terrain It sold the first ATV, the 1982 QuadRunner LT125, which was a recreational machine for beginners.

In 1985 Suzuki introduced to the industry the first high-performance 4-wheel ATV, the Suzuki LT250R QuadRacer. This machine was in production for the 1985-1992 model years. During its production run it underwent three major engineering makeovers. However, the core features were retained. These were: a sophisticated long-travel suspension, a liquid-cooled two-stroke motor and a fully manual 5-speed transmission for 85–86 models and a 6-speed transmission for the 87–92 models. It was a machine exclusively designed for racing by highly skilled riders.

Honda responded a year later with the FourTrax TRX250R—a machine that has not been replicated. Kawasaki responded with its Tecate-4 250. ( is an international corporation based in Japan. It has headquarters in both Chūō-ku, Kobe and Minato Tokyo.

In 1987, Yamaha introduced a different type of high-performance machine, the Banshee 350, which featured a twin-cylinder liquid-cooled two-stroke motor from the RD350LC street motorcycle. ( a Japanese motorized vehicle-producing company (whose HQ is at 2500 Shingai Iwata Shizuoka) is part of the Yamaha Corporation. Heavier and more difficult to ride in the dirt than the 250s, the Banshee became a popular machine with sand dune riders thanks to its unique power delivery. The Banshee remains popular, but 2006 is the last year it will be available in the U. S. (due to EPA emissions regulations); it is still available in Canada, however.

Shortly after the introduction of the Banshee in 1987, Suzuki released the LT500R QuadRacer. This unique quad was powered by a 500 cc liquid cooled two stroke engine with a 5-speed transmission. This ATV earned the nickname "Quadzilla" with its remarkable amount of speed and size. While there are claims of 100+ mph stock Quadzillas, it was officially recorded by 3&4 Wheel Action magazine as reaching a top speed of over 79 mph (127 km/h) in a high speed shootout in its 1988 June issue, making it the fastest production ATV ever produced. Suzuki discontinued the production of the LT500R in 1990 after just 4 years.

At the same time, development of utility ATVs was rapidly escalating. The 1986 Honda FourTrax TRX350 4x4 ushered in the era of four-wheel drive ATVs. Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to Other manufacturers quickly followed suit, and 4x4s have remained the most popular type of ATV ever since. These machines are popular with hunters, farmers, ranchers and workers at construction sites.

Safety issues with 3-wheel ATVs caused all manufacturers to switch to 4-wheeled models in the late '80s, and 3-wheel models ended production in 1987, due to consent decrees between the major manufacturers and the Consumer Product Safety Commission—the result of legal battles over safety issues among consumer groups, the manufacturers and CPSC. The United States Consumer Product Safety Commission (U S CPSC is an independent agency of the U The lighter weight of the 3-wheel models made them popular with some expert riders. Cornering is more challenging than with a 4-wheeled machine because leaning into the turn is even more important. Operators may roll over if caution isn't used. The front end of 3-wheelers obviously has a single wheel, making it lighter, and flipping backwards is a potential hazard, especially when climbing hills. Rollovers may also occur when traveling down a steep incline. The consent decrees expired in 1997, allowing manufacturers to, once again, make and market 3-wheel models, though there are very few marketed today.

Models continue, today, to be divided into the sport and utility markets. Sport models are generally small, light, two wheel drive vehicles that accelerate quickly, have a manual transmission and run at speeds up to 90 miles per hour (145 km/h). Two wheel drive or 2WD describes vehicles with a Drivetrain that allows two Wheels to receive power from the Engine simultaneously Utility models are generally bigger four-wheel drive vehicles with a maximum speed of up to 72. Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to 5 miles per hour (104 km/h). They have the ability to haul small loads on attached racks or small dump beds. They may also tow small trailers. Due to the different weights, each has advantages on different types of terrain.

Six wheel models often have a small dump bed, with an extra set of wheels at the back to increase the payload capacity. They can be either 4-wheel drive (back wheels driving only), or 6-wheel drive.

Racing models

Sport models are built with performance, rather than utility, in mind. To be successful at fast trail riding, an ATV must have light weight, high power, good suspension and a low center of gravity. These machines can be modified for such racing disciplines as motocross, woods racing (also known as cross country), desert racing (also known as Hare Scrambles), hill climbing, ice racing, speedway, Tourist Trophy (TT), flat track, drag racing and others. Motocross is a form of Motorcycle sport or All-terrain vehicle racing held on enclosed Off road circuits Off-road racing is a format of racing where various classes of specially modified vehicles (including cars trucks motorcycles and buggies compete in races through Off-road In Computer science, hill climbing is a mathematical optimization technique which belongs to the family of local search. Ice racing is a form of motor racing It utilizes cars, Motorcycles Snowmobiles All-terrain vehicles or other motorized vehicles In North American Auto racing, particularly with regard to NASCAR, a short track is a Racetrack of less than one mile (1 Drag racing is a competition in which objects compete to be the first to cross a set finish mark usually from a dead stop and in a straight line Examples of high-performance models(racing) include the Yamaha YFZ450, Honda TRX450R, Suzuki QuadRacer R450, Kawasaki KFX450R, Can-Am DS450,Polaris Outlaw 525 S, Outlaw 450 MXR. The TRX 450R is high performance All-terrain vehicle manufactured by Honda powersports As well as the original sport models no longer produced, Honda TRX250R and the Suzuki LT250R Quadracer. The Honda TRX250R was a sport ATV manufactured by Honda between 1986 and 1989 ATVs designed for fast trail riding include the Yamaha Raptor 700R/660R, Yamaha Raptor 350, Kawasaki Mojave 250, Kawasaki Lakota Sport 300, Honda Sportrax 400EX, Suzuki QuadSport Z400, Kawasaki KFX400, Bombardier/Can-Am DS650, Can-Am DS-450,Arctic Cat DVX400, Polaris Scrambler 500, Polaris Outlaw 500, Polaris Outlaw 525 (independent rear suspension IRS), Kawasaki KFX700, Polaris Predator 500 and Can-Am Renagade 800, ADLY 320U Commander, 320S Taifun, New Force 500S/500L Hunter, Gamax AX 300 Tenet, AX500 EFI Emperor.

Criticisms of ATVs

Since the late 1980s, ATVs have been associated with illegal youth activity such as underage drinking. This has led to greater conflict between ATV users and child-safety advocates, rural landowners, outdoor recreationalists and environmentalists.

Safety Issues in U. S.

Since the expiration of the consent decrees between the major manufacturers and CPSC in April of 1998, the manufacturers have entered into "voluntary action plans" that mimic the previously mandatory consent decrees. However, despite the move from 3-wheel to 4-wheel models and the action plans, some deaths and injuries still occur. Statistics released by CPSC show that in 2005, there were an estimated 136,700 injuries associated with ATVs treated in US hospital emergency rooms. In 2004, the latest year for which estimates are available, 767 people died in ATV-associated incidents. According to statistics released by CPSC, the risk of injury in 2005 was 171. 5 injuries per 10,000 four-wheel ATVs in use. The risk of death in 2004 was 1. 1 deaths per 10,000 four-wheelers in use. ^[4] Focus has shifted to machine size balanced with the usage of ATVs on state run land categorized by age ranges and engine displacements—in line with the consent decrees. ATVs are mandated to bear a label from the manufacturer stating that the use of machines greater than 90 cc by riders under the age of 12 is prohibited.

Critics point out that blanket policies concerning age are not sufficient and often use, as example, that early-teen male children are physically larger and stronger than many adult women riders. Some jurisdictions have either banned minors (typically those under 12 years of age) from using ATVs or are considering such legislation. In Law, jurisdiction (from the Latin ius iuris meaning "law" and dicere meaning "to speak" is the practical Authority In law the term minor (also infant or infancy) is used to refer to a person who is under the age in which one legally assumes Adulthood and is legally Legislation (or " Statutory law " is law which has been promulgated (or " Enacted quot by a Legislature or other Governing Advocates of ATVs argue that starting younger improves safety. They recommend that children can develop the necessary expertise by starting at as young as 6 years of age instead of waiting until age 18. The U. S. Consumer Product Safety Commission approved the sale of sub-50cc ATVs for use by children as young as age 6.

In 1988, the All-terrain Vehicle Safety Institute (ASI) was formed to provide training and education for ATV riders. The cost of attending the training is minimal and is free for purchasers of new machines. Successful completion of training is in many states a minimum requirement for minor-age children to be granted permission to ride on state land.

According to the New York Times September 2, 2007, the Consumer Product Safety Commission met in March 2005 to discuss the dangers of ATVs. Data from 2004 showed 44,000 children under 16 injured while riding ATVs, 150 of them fatally. ^[5] Says the Times, "National associations of pediatricians, consumer advocates and emergency room doctors were urging the commission to ban sales of adult-size ATVs for use by children under 16 because the machines were too big and fast for young drivers to control. But when it came time to consider such a step, a staff member whose name did not appear on the meeting agenda unexpectedly weighed in. " That staff member was John Gibson Mullan, "the agency’s director of compliance and a former lawyer for the A. T. V. industry" - the Times bases the claim on a recording of the meeting. Mullan reportedly said that the existing system of warnings and voluntary compliance was working. The agency's hazard statistician, Robin Ingle, was not allowed to present a rebuttal. She told the Times in an interview, "He had hijacked the presentation. He was distorting the numbers in order to benefit industry and defeat the petition. It was almost like he still worked for them, not us. "

U. S. EPA Concerns

Emissions

Due to the lack of emission controlling hardware and software, for year 2000 all recreational spark-ignited (SI) non-road vehicles (of which ATVs are a subset) contributed 8% of HC, . 16% of NOx, 5% of CO and . 8% of PM emissions for the entire non-road US EPA family. The entire range of non-road emissions accounted for 49% of engine produced emissions of all types. ^[6] While recreational SI vehicles produce an aggregate of <4% of all HC emissions in the US, based on the relatively small population of ATVs (<1. 2M) and small annual usage (<350 hrs), EPA emission regulations now include such engines, starting with model year 2006. ^[7]

In Minnesota alone it is projected there will be more than 1 million registered ATVs by 2010. There are about 300,000 in the state now.

Land Usage

Some countries where fencing is not common, such as the US, Canada and Australia, ATV riders knowingly cross privately owned property in rural areas and travel over public/private properties where their use is explicitly limited to trails. Ownership is the state or fact of exclusive rights and control over Property, which may be an object, land/real estate, Intellectual property Rural areas can be large and isolated (also referred to as "the country" and/or "the countryside over the course of time Subsequently, environmentalists criticize ATV riding as a sport for excessive use in areas biologists consider to be sensitive, especially wetlands and sand dunes; and in much of inland Australia. Environmentalism is a broad philosophy and Social movement centered on a concern for the conservation and improvement of the environment. A wetland is an area of Land consisting of Soil that is Saturated with Moisture, such as a Swamp, Marsh, or Bog In physical Geography, a dune is a Hill of Sand built by Aeolian processes.

While the deep treads on some ATV tires are effective for navigating rocky, muddy and root covered terrain, these treads also dig channels that may drain boggy areas, increase sedimentation in streams at crossings and damage groomed snowmobile trails. A bog or mire is a Wetland type that accumulates Acidic Peat, a deposit of dead plant material &ndash usually Mosses but also Sedimentation describes the motion of Molecules in Solutions or particles in suspensions in response to an external force such as gravity Studies have also shown that ATVs may help in the spread of invasive species such as knapweed and Lantana. Centaurea ( Cen-tau-ré-a) is a genus of about 350-500 Species Species in this genus include Centaurea adpressa Lantana is a Genus of about 150 Species of perennial Flowering plants native to tropical regions of the Americas Despite some limited studies showing the impacts of unregulated Off-Road Vehicle (ORV) use, the vast majority of ORV use on public lands is regulated. An off-road vehicle is considered to be any type of Vehicle which is capable of driving on and off paved or Gravel surface Moreover, running counter to the popular misconception that ATV and ORV use is a leading cause of damage to the landscape and sensitive habitats in general, the overwhelming evidence of human growth patterns upon the landscape indicates damage to the sensitive habitats is caused by unmitigated growth of single-family housing planning and extractive industries.

ATV advocacy groups have been organized to purchase property or obtain permission of landowners, or both. Many US states pay the clubs to build and maintain trails suitable for ATV riding and educate ATV riders about responsible riding. Many have also formed separate governing bodies that license ATVs separately from other ORVs. The monies from gas taxes and registration are used to create more trails to ride and to perform grooming and maintenance.

Self-regulation has proven particularly difficult. One public complaint against ATVs is excessive noise. Although the majority of ATVs comply with noise regulations, there are those whose intentional violation can disturb the activities of other recreational users for miles across open landscapes. Tampering with an ATVs exhaust silencer and spark arrestor is illegal on all US federal lands and most state lands. A spark arrestor is a device intended to prevent combustible materials usually Sparks or other tiny flaming Debris, from escaping However, enforcement is spotty. It is also possible to install after-market exhaust systems that do not have spark arrestors.

Further, off-road vehicles, including ATVs, frequently go off designated trails, thus creating new spur trails. This process is called trail proliferation. In areas where the vehicles are confined to designated trails, enforcement is fairly straightforward, however some states have laws that permit use on vaguely defined, undesignated trails.

Fellow outdoor recreationalists who have expressed concern about irresponsible ATV use include snowmobile users who resent improper use of exclusive snowmobile trails, ATV trail-riders whose trails have been damaged by improper use, and hunters whose game has been driven off by those riding during prime hunting times.

Nationally, the US Forest Service considers managed ATV use to be a legitimate activity in national forests, yet it also lists their unregulated use as one of the four greatest threats to long-term forest management. The US Forest Service recently released a national travel management plan designed to minimize the negative environmental impacts of ATVs while providing a safe, sustainable and enjoyable opportunity for ATV users.
