A system that steers the rear wheels of the three wheeled vehicle in coordination with the operator turning the front wheel that improves handling, performance and safety. The rear wheels are steered by a rear end mounted powered steering rack that is controlled by a steering control computer that receives input from a variety of sensors including a sensor for vehicle speed and a sensor in the steering neck that measures the angular rotation of the handlebars as they are turned by the operator. Based on these inputs, using proprietary programming the steering control computer calculates the rate, timing and direction to turn the rear wheels. Rear steering offers advantages over front wheel only steering including being easier for the operator to turn the vehicle, a smaller turning radius, better straight line stability, better high speed handling, improved corning performance, improved steering response and improved safety.
