| 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. |
