A power steering system for a motorcycle, such as a motorcycle trike. The power steering system includes a piston having a piston rod disposed within a cylinder. A distal end of the piston rod is pivotably coupled to a fork tube of a motorcycle fork. A power source drives the piston rod away from the cylinder and retracts the piston rod within the cylinder. A control switch controls the piston between a neutral position, a first turn position, and a second turn position. The neutral position includes the piston rod partially extended from the cylinder. The first turn position includes the piston rod extending further from the cylinder than the neutral position. The second turn position includes the piston rod retracted further within the cylinder than the neutral position.
