4 Wheelers explained:

4 Wheeler: Also called an ATV or all terrain vehicle is a small, open motor vehicle having one seat and three or more wheels fitted with large tires. It is designed chiefly for recreational use over roadless, rugged terrain. The term "all-terrain vehicle" is used to describe a number of different, small open motorised buggies and tricycles designed for off-road use. The 4-wheeled versions are also called quad bikes or more often quads. Models with 3 wheels are called all-terrain (motor)cycles or ATCs. 6 and 8 wheel models exist for specialized applications. The rider sits on these models just like on a motorcycle, but the extra wheels make them more stable at slow speeds.

Sport models are often built with a mind towards motocross racing, either in the design of the machine or at least in the marketing of it. To be successful at motocross racing, a quad must have light weight, high power, good suspension and a low center of gravity. There are many other types of riding and racing such as GNCC (woods racing), Baja (desert racing), hill climbing, and trail riding.6 wheel models 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.

Some of the most popular manufacturers of 4 wheelers/ATVs are:
Honda
Kawasaki
Bombardier Recreational Products
KPX
Yamaha
Suzuki
Polaris Industries
Cannondale

4 Wheeler Q&A's, Tips, Troubleshooting Section:

You’re making good time down an old brush road, but as you circumvent a blow-down, a sharp branch punctures your sidewall. What now?

A tire repair kit and a pump should get you out. You can fix a surprisingly bad tear with those plugs that you stick into the hole and melt down; depending on the size of the hole, you might have to use a few plugs to make an adequate seal. While I know riders who continued to run tires with plugged sidewalls for a full season, it’s not a good idea. It’ll get you out of the bush, but the tire should be replaced once you’re back home.
