just picked this up from a guy in a nearby town. has 500mi. on it. looks like brand new. its air cooled with a 20in 154in. 1 1/2in lugged track. has under seat storage and a large back rack. been wanting a wide track for years due to our deep snow and slush conditions on our lakes. my brother has a 2000 bearcat 550 fan widetrack and when the rest of us get stuck in deep slush he keeps going. this sled is the number 1 selling snowmobile in Russia if that says anything about its durability. if taken care of my son might inherit it someday. the design has had only minor changes since it debuted in 87'. same motor. very easy to work on yourself. used it on the lake 4 days ago. im liking it alot. hauled my loaded down otter magnum w 2 big guys and it barely noticed.
