Popular brands of four wheelers include Arctic Car, Honda, Yamaha, Kawasaki, Suzuki and Polaris. Honda and Polaris produce the most popular models of four wheelers as of 2014.
A four wheeler is also called an ATV, which stands for all terrain vehicle, or quad. The first four wheeler, the Quadrunner LT125, was developed by Suzuki in 1982. The four wheels help to provide additional stability compared to a motorcycle, though a 2003 study showed that four wheelers are as dangerous as motorcycles. Engine sizes of four wheelers range from 49 to 1,000 cubic centimeters. Children under the age of twelve are not allowed to ride four wheelers larger than 90 cubic centimeters. Four wheelers are not street legal in the United States as of 2014. The two types of four wheelers are sport and utility. Sport models are typically two wheel drive, small and fast. They can be used for racing clubs and other types of competitions, such as obstacle courses. Utility models are typically four wheel drive, larger and have towing ability. Honda developed the first four-wheel-drive ATV, the FourTrax TRX350 4x4, in 1986. As of 2014, four-wheel-drive ATVs have been the most popular type of ATV since their introduction.
