A 100cc ATV is a type of all-terrain vehicle usually designed for children or smaller adults. The 100cc measurement refers to the size of the engine's displacement, which is measured in cubic centimeters, or cc. Generally, smaller numbers refer to smaller engines with less power, while higher numbers refer to more powerful engines. A 100cc ATV is likely to produce less power and therefore be unable to reach higher speeds than larger ATVs, which is why these machines are usually suitable for children. Many ATVs of this size will feature a remote shut-off that will allow a parent to cut power to the engine should a child lose control of the vehicle.
An all-terrain vehicle, or ATV, usually features four wheels that have rubber tires with aggressive treads. These machines are designed for use over varied terrain, and they are generally fairly stable and easy to maneuver. Larger vehicles can be difficult for a child to maneuver, however, so a 100cc ATV is designed to increase mobility and maneuverability. Smaller ATVs do exist for smaller children; 50cc models, for example, are exceptionally small and are usually suitable for kids who are very new to the sport. A 100cc ATV is designed for a child with a bit more experience; it can usually accommodate a child ranging from age 7 or 8 up to 15 or 16.
Like other sizes of ATVs, the 100cc ATV can be built in a variety of styles. Some ATVs, for example, are built for racing purposes, so they tend to be lightweight and easily maneuverable. Others are more utilitarian and will feature racks for hauling luggage or other items, as well as a low center of gravity that makes the ATV useful for hauling. In either case, the ATV will feature body panels made of certain types of plastic that will protect engine, drive, and suspension components from damage.
The rider sits on top of the vehicle on a saddle, and steering is accomplished using handlebars. A handbrake lever will be mounted to one side of the handlebars, and a clutch lever will be mounted to the other side of the handlebar if the 100cc ATV features a manual transmission. Some will feature automatic transmissions, in which case two brake levers may be present on the handlebars. Some ATVs will feature a foot brake pedal as well to give the rider more options for slowing or stopping the vehicle.
