The present invention relates to a three-wheeled vehicle comprising a frame with engane, drive gear and at least one driven wheel at the rear, and two front wheels which are used in part to steer the vehicle. The vehicle can also be steered in that the frame with engine, drive gear and the driven rear wheel can be banked over to the side like a motorcycle. The present invention relates in particular to a design which helps to move the centre of gravity when such a vehicle is tilted to the side so that, inter alia, it is easier to right the vehicle. Furthermore, the present invention makes it possible to affect and determine the driving characteristics of the vehicle by varying different design parameters within the scope of the present invention. The invention also relates to a special design for the mounting of footboards on which the driver of the vehicle can place his/her feet when driving the vehicle. The special design according to the invention contributes actively to changing the geometry between the footboards and the frazne of the vehicle when the vehicle is used and especially where it is "tilted" to the side to steer the vehicle.
