Furthermore, the actuator unit can be designed such that it can move one or more articulation elements, via which the at least one of the further vehicle components is connected to the vehicle body. The articulation element or the articulation elements can each comprise a boom with one or more pivot bearings.

Furthermore, the driving dynamics optimization device can be configured such that the movement of the at least one further vehicle component from the first position to the second position is a movement in the vehicle center plane of the single-track vehicle. The vehicle center plane of the Einspurfahrzeugs extends in an upright state of the Einspurfahrzeugs on a flat surface with uncontrolled steering perpendicular to the ground and by the wheel contact points of the Einspurfahrzeugs.

According to a further embodiment, the driving dynamics optimization device is set up to move the at least one of the further vehicle components as a function of one or more driving dynamics variables in one or more further positions relative to the vehicle body, in particular to change the center of gravity of the single-track vehicle in dependence on a driving maneuver.

According to a further embodiment, the single-track vehicle has an electric drive, wherein the at least one further vehicle component, which can be moved from the first position to the second position as a function of at least one driving dynamics variable, is the energy storage unit of the electric drive. The energy storage unit may in particular be a battery or an accumulator.

According to a further embodiment, the driving dynamics optimization device is set up in such a way that the at least one further vehicle component is moved forward in the direction of travel when the single-track vehicle is positively accelerated. Furthermore, the vehicle dynamics optimization device can be set up in such a way that the at least one further vehicle component is moved rearward in the direction of travel in the event of a negative acceleration or deceleration of the one-track vehicle.

In the single-track vehicle described here, an optimal center of gravity position can be achieved with each driving maneuver of the single-track vehicle.
