A tilting vehicle with a front frame section has a longitudinal axis, a driver's seat and one or more wheels that are able to turn about a front wheel steering axis located transversely to the longitudinal axis. The vehicle has a rear frame section with two wheels that is connected to the front frame section such that it can tilt. The vehicle can have a tilting device operated by the driver, for relative tilting of the front and rear frame sections. A sensor measures a force or movement on the front wheel for controlling the tilting device. The rear wheels can be turned about a rear wheel steering axis located transversely to the longitudinal axis or can be tilted about a rear wheel tilt axis located essentially in the direction of the longitudinal axis in order to prevent oscillations of the vehicle at relatively high speeds.
