I was told almost all Polaris sleds can be converted to a 2up. There's an '05 Fusion 900 riding around here that has the second seat installed. I've had dad on the back of my sled, it handled better than the Touring Deluxe I used to have. As for Ski-doo, have you seen the mod with the 2up seat? They're all over the trail. No handle at all if it wasn't originally designed for the 2up option. Either that or they forgot to adjust their suspension for the second person :bash:
