A motor-adjustable X-ray system comprises a C-arm, which has two degrees of freedom and is adjustable with a motor support. The motor support has a force pickup device which is provided to detect a force exerted by an operator when manipulating the C-arm. The force pickup device is configured to detect a plurality of directional components of the exerted force and to cooperate with an evaluation unit, by which as a function of the plurality of the directional components of the exerted force, different amounts of motor support of the C-arm in the two degrees of freedom are established via the evaluation unit.
