A vehicle ( 1 ) in the form of a motorcycle comprises a support wheel system located between the front and rear wheels ( 3, 4 ) of the motorcycle. The front wheel is arranged in a wheel suspension ( 5 ), in or with which the front wheel can, depending on steering actions with steering means ( 7 ), be turned into different desired turning steering positions. In the longitudinal section plane of the vehicle in the vertical direction, there is a projection (a) at the front wheel on account of the said suspension. The support wheel system is arranged to assign to the support wheels ( 10, 11 ) turning steering positions which depend on the turning steering positions of the front wheel and result in the vehicle, when performing turning steering in primarily the lower speed range of the vehicle, taking up with its said longitudinal section plane a vertical position or a position in relation to the said vertical position which is inclined slightly in the same direction (R) as the assigned turning steering direction of the front wheel. In this way, the driving standard can be raised considerably, especially at lower speeds.
