Dual Track Snowmobiles have been designed to perform various work tasks. The manufacturers of the Dual Track Snowmobiles included Aktiv from Sweden, who made the famous Aktiv Grizzly, Ockelbo, another manufacturer from Sweden who made the 8000, and Bombardier who made the models Alpine and Alpine II. Bombardier diacontinued the manufacture of dual track snowmobile in the early 2005’s. In the current market, there are only two manufacturers of dual-track snowmobiles. One is the Russia’s Buran and the other is the Alpina snowmobiles from Italy with the models, Sherpa and Superclass.
