Aktiv Grizzly

The Aktiv Grizzly was a dual-track snowmobile made by Aktiv Maskin Östersund AB in Sweden from 1979 to 1991. The Grizzly is still recognized as one of the best dual-track snowmobiles in the world. The snowmobile's tracks covered almost one square meter, making it well suited for use in deep snow. Similar dual-track snowmobiles include Bombardiers Ski-Doo Alpine, Ski-Doo Alpine 2 and Ockelbo 8000. Currently two dual-track snowmobile are in production, one in Russia under the name "Buran" and one in Italy, "Alpina Sherpa".

Specifications
The Grizzly snowmobile was equipped with dual 38 x 384 cm tracks and a single front ski. Dual front skis were available for the XP model. The engine was a 497 ccm Rotax 503 Scandinavia, which produced 38 HP (28 kW) at the snowmobile's maximum RPM of 5700. In the mid 80's, the Grizzly switched from the traditional wheel-based chassis to a flexible joint-bogie, which made the ride smoother and the passability much better. The carburetor was a VM 32, supplied by Mikuni. De luxe models of earlier Grizzlies had a transmission with one forward and one reverse gear. The last model produced (XP, 1989–1991) had two forward speeds. == Links and resources ==
