Abstract: An apparatus provides a restoring moment for a two-wheeler steering mechanism. A mounting device mounts the apparatus on a two-wheeler frame. A coupling device couples the apparatus with a fork shaft, and has a rotational axis. An energy storing device stores a restoring force. A force transmitting device transmits steering force to the energy storing device. The force transmitting device has a force transmitting point that is eccentric to the rotational axis, and forms a force action line through the eccentric force transmitting point and an application point of the force transmitting device on the energy storing device for transmitting the steering force to the energy storing device. In a neutral position of the apparatus, the force action line and a straight line running through the rotational axis and the application point enclose an angle. A two-wheeler frame, a two-wheeler steering and a two-wheeled vehicle are also provided.

Abstract: A steering device comprising of a one-piece T-shaped bar stem that is mounted to a head tube and that has two essentially parallel ends to which attachment clamps are mounted, each clamp holding the handlebar tube. The handlebar tube is arranged parallel to the bar stem's ends. The wall thickness of the handlebar tube changes along the longitudinal axis of the handlebar tube. Within reinforcement areas, which serve to receive the attachment clamps, the wall thickness reaches its maximum. Within a first area of the handlebar tube having a constant outer diameter the wall thickness reaches its minimum. To prevent radial recesses within the handlebar tube, intermediate areas are formed, having an inner radius that increases in measure from a radius being equal to the inner radius of the first area to a radius being equal to the radius of the inner radius of the reinforcement area.
