1991 Ski Doo Mach I What I can say about this that it is a sled that you never see around anymore. Newer track, no picks, Update! I had this sled serviced last summer. Not a beginner sled, you could find a tree fast. This sled will tear pass a lot of modern sleds with ease 617cc. No trades. Ready to ride, Just installed a recovered seat too. Cash only no trades
