So is this what mine started life as? Forgive my newbness but I just bought this sled recently without doing any research, which is unlike me, but I got a smokin deal and bought it on the spot. It looks exactly like yours but the PO put a 144" track extension on it last winter.
So is there any significance to the X? I thought the MXZX was a 440 race machine. Also what does the Formula XPS-II Edition mean? All I can find about that is that it was an oil or something.
The X is just skidoo's package they offered back then. I believe it was an upgrade from there adrenaline package. It came with piggyback shocks up front and all shocks were rebuildable. The X package came with adjustable toe holds, handle bar hooks, x package seat, hand guards, and an X style short windshield. I believe this sled was as close as a consumer could get to a race sled without actually buying a race sled back then. To my knowledge I believe the formula xp-s11 edition was like you said just the oil that is used. Back when it came out I think there were race sleds and race trailers painted with the XP-S11 edition on them. My sled is a 600 and it came with a 1 inch track but my buddys sled is exactly the same except his is an 800 and it came with an 1 1/4 track. Your sled looks real nice with the extension on it. Hope you enjoy it this winter and congratulations on your new purchase!
