Abstract
A vehicle has a frame, at least one front wheel connected to the frame, at least one front suspension assembly connecting the at least one front wheel to the frame, at least one rear wheel connected to the frame, and at least one rear suspension assembly connecting the at least one rear wheel to the frame. At least one of the at least one front and at least one rear suspension assemblies includes an air spring. A seat is connected to the frame. An engine is connected to the frame and is operatively connected to at least one of the wheels. An air compressor is connected to the frame and fluidly communicates with the at least one air spring for supplying air to the at least one air spring. A control unit is electrically connected to the air compressor for controlling an operation of the air compressor.
