My friend has an 06 Rage. I was skeptical at first, but after three trips with him last year (1500 miles) it is a damn nice sled. The four stroke is really smooth, and the mileage, no oil, smooth ride, control...it is a great touring/trail comfort sled. My F7 beats it (I think the Rage is about 1000cc), but the thing still moves. I think it is 550 lbs or something, it isn't as heavy as I thought it would be, and I'll say again, the smoothness of the 4 stroke was pretty appealing. (He can just crawl up the trailer at like .25 mph, very consistent low end power.) He loves the way it handles, but he is more of a touring type of rider. It's like a cadillac.
We saddlebag it all over the U.P. and he is always bitching about me having to stop for gas when he has 2/3 of a tank left. LOL I'll tell you, I'm a two-stroke lover but that sled has opened my eyes to the possibility of a four stroke in the future. They will just keep improving them too, I like the Jaguar Z1 AC put out this year, it will be interesting to see how they keep developing the 4 strokes.
My friend is VERY happy with the Rage. We did a lot of off trail riding, forest roads mainly, but a lot of 3 to 4 ft powder and he had no probs getting stuck.
