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-. The Grizzly was also produced and sold on license by Polaris Industries under the name "Polaris Grizzly de luxe". This version had a Fuji 440 ccm engine. Also Finnish company Winha sold earlier grizzly (1982–1983) with own brand name Winha. Winha Grizzly had either traditional wheelbased bogie or flexible joint-bogie and it was equipped either with Artic Spirit AB 50, A3 engine or Fuji EC 44-2PM-3000 engine. Currently there are two dual-track snowmobile in production, one in Russia under the name "Buran" and one in Italy under the name "Alpina Sherpa". == Technical Data == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aktiv Grizzly」の詳細全文を読む スポンサード リンク
