Gear unit for a two-wheeled vehicle

A shift system for shifting a gear unit, comprising:

• at least one movably arranged selector shaft;
• and
• at least one switch element;
• wherein a selected position of the switch element is variable relative to the switch element by a movement of the selector shaft;
• and
• wherein a drive shaft rotatable about a center axis is configured as part of the shift system such that the drive shaft is rotationally fixedly connected to a component of the gear unit in at least one direction of rotation in a first selected position of the switch element, and is disconnectable from the component of the gear unit in any direction of rotation in a second selected position of the switch element;
• and whereas
• the switch element is configured in conjunction with the drive shaft such that at least a portion of the switch element co-rotates about the center axis with a rotation of the drive shaft;
• and
• the relative movement of the switch element relative to the selector shaft is induced by the part of the switch element rotating with the drive shaft, so that the movement of the switch element between the first and the second selected position is effected by a force branched off from the drive movement of the drive shaft.
