I rode with one all day yesturday with not quite enough snow in central Idaho. Rode it some, was very impressed. He is quite a rider and has tinkered with the clutching some and to me it was spot on, to him more work to be done. But... I was shocked at how light it was, just a night and day difference from my 07 xrs. Mine is strong, well clutched and it felt like a hog after riding the 08 XP. Never a problem in a couple of hundred miles and we unfortunately hit a few rocks, and clipped a stump or two, but with some luck, and a seemingly solid chassis neither sled showed any damage. My initial conclusion is that it is a solid well put together light sled! No problems and we tested it more than either one of us would have liked to. My buddy is still tweeking on his suspension set ups and the clutching, but it runs awsome already and with some more adjustments, I can only imagine. I will own one as soon as I can! No belt problems and no mechanical issues. Just a lot of fun and it can climb!
