Abstract
A track system for a vehicle having a rear swing arm that is movable between a compressed suspension position and an extended suspension position. The track system has a frame and a dynamic traction device. The frame is pivotably attachable to the swing arm. The dynamic traction device has at least two elongate portions, one of which is movable relative to the other between a retracted position and an extended position and biased toward the retracted position. In use, the elongate portions interconnect the vehicle and the frame. When the vehicle is lifted off terrain, during at least a part of a movement of the swing arm from the compressed suspension position toward the extended suspension position, the dynamic traction device applies a torque to the frame and thereby changes a longitudinal angular position of the frame counter-clockwise relative to a left side of the vehicle.
