Abstract

A two-wheeled motorcycle having a frame carrying a drive motor, a radio, a servo mechanism controlled by the radio, and a power source for driving the motor, radio, and servo. The servo mechanism includes a weight which may be moved to one side or the other of a generally vertical plane extending through the motorcycle when it is in an upright position. The steering crown is arranged so that a plane including the axes of the down tube and the fork is behind the main pivot. The axle of the front wheel is in the plane of the fork axes. The plane including these axes intersects the surface upon which the motorcycle rests at an angle in the range of about 20.degree.-25.degree. relative to vertical. The arrangement of the steering crown is such that, when the servo mcves the weight to one side of the generally vertical plane, the front wheel will tend to turn into the direction in which the weight is moved. This is accomplished by insuring that the plane including the axes of the down tubes and forks is behind, but parallel to, the pivot axis of the crown, relative to the frame.
