The snowmobile is equipped with dual 38 x 384 cm tracks for maximum float and traction and single front ski (also dual front skis has been available for XP). Tracks cover area almost 1 m2, it is extremely well suited for deep-snow operations. The Grizzly is powered by a reliable 497 ccm Rotax 503 Scandinavia, producing 38 HP (28 kW) at 5700 RPM. The carb is a VM 32, supplied by Mikuni. Earlier Grizzly (de luxe) have 1+N+1 gearbox and last model (XP) (1989–1991) have 1+N+2 gearbox. The Grizzly was produced from 1979 to 1991. It is still recognized one of the best dual track snowmobile in the world. Both Bombardiers Ski-Doo Alpine, Ski-Doo Alpine 2 and Ockelbo 8000 are similar dual-track snowmobiles. In the mid 80's, the Grizzly switched from the traditional wheelbased bogie to a flexible joint-bogie, which made the ride smoother and the passability much better.

Aktiv started making tracked vehicles 1957 when they started making Snow Trac, a small personal Snowcat that is roughly the size of a modern compact car. Aktiv started making small snowmobiles in 1973 when they bought Snö-Tric brand. First dual-Trac snowmobile made by Aktiv was Snö-Tric Blå 75- and SC 20/2 75-.
