An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike or quad (if it has four wheels), as defined by the American National Standards Institute (ANSI), is a vehicle that travels on low-pressure tires, has a seat that is straddled by the operator, and has handlebars, similar to a motorcycle. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. It is street-legal in some countries, but not in most states, territories and provinces of Australia, the United States, and Canada.
By the current ANSI definition, ATVs are intended for use by a single operator, but some ATVs, referred to as tandem ATVs, have been developed for use by the driver and one passenger.
The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six or eight wheel (tracked) models exist and have existed historically for specialized applications. Multiple-user analogues with side-by-side seating are called utility terrain vehicles (UTVs) or side-by-sides to distinguish the classes of vehicle. Both classes tend to have similar powertrain parts. Engine sizes of ATVs for sale in the United States as of 2008 ranged from .
History 19th century
Royal Enfield built and sold the first powered four-wheeler in 1893. It had many bicycle components, including handlebars. The Royal Enfield resembles a modern ATV-style quad bike but was designed as a form of horseless carriage for road use. Royal Enfield Early History
Six-wheeled AATVs
The term "ATV" was originally coined to refer to non-straddle ridden, typically six-wheeled, amphibious ATVs, such as the Jiger produced by the Jiger Corporation, the Amphicat produced by Mobility Unlimited Inc, and the Terra Tiger produced by the Allis-Chalmers Manufacturing Company in the mid-1960s and early 1970s. With the introduction of straddle ridden ATVs, the term AATV was introduced to define the original amphibious ATV category.
Three-wheeled ATVs
The first three-wheeled ATV was the Sperry-Rand Tricart. It was designed in 1967 as a graduate project of John Plessinger at the Cranbrook Academy of Arts near Detroit. The Tricart was straddle-ridden with a sit-in rather than sit-on style (similar to the contemporaneous Big Wheel toy). In 1968 Plessinger sold the Tricart patents and design rights to Sperry-Rand New Holland who manufactured them commercially. Numerous small American manufacturers of 3-wheelers followed. These small manufacturers were unable to compete when larger motorcycle companies like Honda entered the market in 1969.
Honda introduced their first sit-on straddle-ridden three-wheeled all-terrain vehicle in 1969, known as a US90, as a 1970 Model. Variations would be popularized in the James Bond movie, Diamonds Are Forever and TV shows such as Doctor Who, Magnum, P.I. and Hart to Hart. In 1973, Honda trademarked the term "All Terrain Cycle" (ATC), applying it to all Honda's three-wheeled ATVs; it became a universal name associated with all vehicles of this type. It was directly influenced by earlier 6-wheeled AATVs of the sixties, and utilized balloon tires for both a low environmental impact and to compensate for a lack of mechanical suspension.
Honda entered the 1980s with a virtual monopoly in the market, due to effective patents on design and engine placement. By 1980, other companies paid patent royalties to Honda to enter the lucrative ATC field with their own machines. Yamaha introduced their first ATC, the Tri-Moto YZ125. Kawasaki followed suit the next year with the KLT200, while Suzuki produced their first model, the ALT125, in 1982. As the popularity of ATCs increased dramatically, rapid development ensued. The ability to go anywhere on terrain that most other vehicles could not cross soon made them popular with US and Canadian hunters. As other manufacturers were entering the market, Honda was diversifying, offering the ATC250R, the first Sport ATC intended for competition, in 1981. The 1982 Honda ATC200E Big Red was a landmark model. It featured both suspension and racks, making it the first ATC designed specifically for utility, and would become the world's best-selling ATC. Honda followed that effort in 1983 with the ATC200X, an easy-to-handle four-stroke Sport ATC that was ideal for new riders.
Not to be outdone, Kawasaki and Yamaha responded with their own Sport ATCs. 1984 saw the release of the Kawasaki KXT250 Tecate, and Yamaha followed in 1985 with the Tri-Z 250. Both were liquid cooled 250 cc two-strokes capable of giving the Honda ATC250R competition. In response to growing market, American Specialty manufacturer Tiger also introduced a series of ATCs, hand-built-to-order models that included the Tiger 500, the largest displacement ATC produced commercially. While Kawasaki and Yamaha both produced utility ATCs, famously making the KLT 250 Police and Yamahauler respectively, Suzuki turned their attention to building Sport Quads.
Honda continued to diversify their line-up (at peak offering 10 distinct models), releasing the larger, fully suspended 250 cc Big Red utility ATC, and introduced the 350X Sport ATC, their largest displacement machine, in 1985. But the bulk of their sales were the 200cc line, offering six models and selling over 500,000 units in 3 years. Honda's response to the Tecate and Tri-Z, the liquid cooled 1985 and 1986 ATC250R, remains one of the most desirable ATCs of the era, and aftermarket support still follows the machine.
U.S. manufacturers Main articles: Tiger ATV LTD and Polaris Scrambler 250R/es
American-based manufacturers also produced ATCs in this period, albeit in small numbers. Polaris offered the Scrambler in 1985 and 1986, producing appx 1600 units. Speciality manufacturer Tiger ATV also produced a range of ATCs, but their liquidation in 1991 left no official record of how many units were produced. The collector ATV market estimates vary drastically, from 300 to as many as 1000 units total production. Tiger ATCs were offered for three years, with models using two-stroke engines provided by KTM and Rotax.
The Tiger 500 is notable for being the fastest consumer ATC available, with tested top speeds of +80 mph from the stock @6500rpm engine and 5 speed gearbox. With final drive gearing changes, the ATC could exceed 100 mph. However, due to the rarity of the machines the brand never became well-known, and as all Tiger Models were custom-ordered and built to the buyer's specifications for the purpose of factory ATV racing, Polaris is generally known as the first American 'Production' ATV producer.
Production pause Production of three-wheelers was voluntarily ceased by all manufacturers by 1987, in light of safety concerns, and ahead of any legislation. Though later studies showed that three-wheelers were not considered more unstable than four-wheelers (although accidents are equally severe in both classes), manufacturers agreed to a 10-year moratorium on production, and to collectively financing a +US$100 million ATV safety campaign. Despite the moratorium lifting, manufacturers did not return to the ATC market, focusing instead on four-wheeled ATVs. A ban on sales of new or used three-wheelers and a recall of all remaining three-wheelers was proposed by the American Academy of Pediatrics.
These safety issues with three-wheel ATCs caused a shift in the buying public, as the sales of later four-wheel ATV models grew rapidly. While three-wheel models ended production in 1987, agreements between the major manufacturers and the US U.S. Consumer Product Safety Commission to officially cease production and finance safety campaigns moved forward. While the lighter weight of ATCs made them popular with certain riders, manufacturers continued to focus on ATV production.
US Public Law 110-314 US Public Law 110-314, enacted on 8 August 2008, separated ATCs from existing new production ATV safety standards, and requires new standards for three-wheeled ATCs to be drafted. This effectively suspended importation of three-wheeled ATCs, until new standards of safety can be drafted. As of 2020, such standards have not been drafted. While search engines can find informal information suggesting major Japanese manufacturers pressed for this measure due to an influx of inexpensive Chinese ATCs in the American market, no official documentation or cited sources support these claims. Currently, all manufacturers not based in the US are restricted from the manufacture and sale of new Three-Wheeled All Terrain Cycles, until safety standards can be implemented. Below is a summary of Section 232, which effects the ATC ban.
(Sec. 232) Requires the CPSC, notwithstanding any other provision of law, to establish as a mandatory consumer product safety standard a specified American National Standard for four-wheeled all-terrain vehicles developed by the Specialty Vehicle Institute of America. Makes it unlawful for any manufacturer or distributor to import or distribute any new all-terrain vehicle unless: (1) the vehicle complies with the standard, is subject to an all-terrain vehicle action plan, and bears a label certifying such compliance and certain other information; and (2) the manufacturer or distributor is in compliance with the action plan.
Prohibits the importation of new three-wheeled all-terrain vehicles until a mandatory consumer product safety standard applicable to three-wheeled all-terrain vehicles is in effect.
Four-wheeled ATVs (since 1980)
Suzuki was a leader in the development of mass production four-wheeled ATVs. It sold the first model, the 1982 QuadRunner LT125, which was a recreational machine for beginners.
Adventure Vehicles of Monroe, Louisiana made the first quad ATV in 1980. They called it the Avenger 400. Prior to that, Adventure Vehicles made 3 wheel ATVs and a dump body utility 3 wheeler using Kohler 8 hp engines and Comet drive systems (Comet centrifugal belt-driven clutch, and a Comet forward, neutral, reverse transaxle, with a rigid rear axle or rear differential option.) The Avenger 400 was a rigid suspension vehicle with a fiberglass body and welded tube construction. It was a rudimentary vehicle reminiscent of the Tote Gote of the 1960s.
Suzuki sold the first four-wheeled mini ATV, the LT50, from 1984 to 1987. After the LT50, Suzuki sold the first ATV with a CVT transmission, the LT80, from 1987 to 2006.
In 1985 Suzuki introduced to the industry the first high-performance four-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 five-speed transmission (for 1985–1986 models), and a six-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 until recently. It currently remains a trophy winner and competitor to big-bore ATVs. Kawasaki responded with its Tecate-4 250. The TRX250R was very similar to the ATC250R it eventually replaced and is often considered one of the greatest sport ATVs ever built.
