a central portion of the drive shafts from the top of the apparatus this opening allows the tires of the motorcycle to contact the shafts when the tire contacts the drive shafts and the operator of the motorcycle applies power to the wheels the tires turn and translate power to the drive shafts as the drive shafts rotate the drive gears likewise turn and mesh with the large circular gear of the outer platform this movement results in the rotation of the inner platform as noted above the recoil device is fixed to the center of the outer platform and is also attached to the center of the inner platform the function of the recoil is to return the apparatus from the final loaded position where the rectangular opening in the inner platform is furthest from the point where the motorcycle first drives onto the apparatus to the rest position where the rectangular opening in the inner platform is closest to the point where the motorcycle first drives onto the apparatus as the motorcycle translates power to the apparatus facilitating the turn the recoil builds up some recoil spring energy when the motorcycle exits the apparatus a trigger is released that unloads.
