Motorcycles Wallpapers

A motorcycle (or motorbike) is a two-wheeled vehicle powered by an engine. The wheels are in-line, and at higher speed the motorcycle remains upright and stable by virtue of gyroscopic forces; at lower speeds continual readjustment of the steering by the rider gives stability. The rider sits astride the vehicle on a seat, with hands on a set of handlebars which are used to steer the motorcycle, in conjunction with the riders weight shift through their feet which are supported on a set of "footpegs" or "pegs" which stick out from the frame.

Variations exist: some motorcycles are equipped with floorboards instead of footpegs, and sidecars and other three-wheeled variations may also be found.
