A system that stiffens the rear suspension of the three-wheeled vehicle in coordination with the operator turning the front wheel to prevent leaning in turns and thus improve handling, performance and safety. The suspension system is controlled by the suspension control computer that receives input from a variety of sensors including a sensor in the steering neck that measures the angular rotation as the handlebars are turned by the operator. Based on these inputs, using proprietary programming, the suspension control computer calculates the timing, degree and appropriate side rear shock absorbing unit to stiffen. Active suspension offers significant advantages over non-active independent rear suspension in that it minimizes adverse handling characteristics caused by suspension leaning in turns while still allowing the comfort and handling of an independent rear suspension, as opposed to a non-independent rear suspension which provides a poor quality ride.
