Abstract: A weighted track system for snowmobiles. In one embodiment, the rider uses a heavier track to add weight useful in trick jumps. This track is installed prior to jumping and can be used for regular riding. In a second embodiment, weights are added to an existing track to provide the additional momentum. The weights are installed at regular intervals on the track and can be adjustable so that more or less weight can be added as desired. With a weighted track, perfect timing in locking up the brakes while jumping is not s critical; making the performance in jumps is safer and better.
