Both are good sleds...
I doubt you can go wrong with either sled - bear in mind the internet blows things wayyy out of proportion. That being said, every sled needs a little tuning / tweaking to make it all it can be. (Good dealer is a must).
And for the record, the doo 800XP can / does / did beat up on the RT1000 in stock configuration - so did the 05 /06 / 07. Hell, my 04 159X would - just needed to pack a lunch when climbing - it was a slow machine in terms of track speed. But the M1000 is another story, unless the guy on it cannot ride, or it is set up poorly. Make no mistake - it comes down to the rider when you are talking stock to stock. FredW, I do not doubt your 885 twin will beat up on an M1000, especially cause Ralph built it. But if it would kick a** and take names when it was stock, I doubt you would have spent that kind of coin. I've no doubt in my mind that the XP800 is the best sled in the 800 class, but you are comparing apples to oranges. I've ridden both, and would have an XP800 in the stable as a backup sled this year if the local dealer had been easier to deal with. The way it worked out, I got a smoking deal on an M8 and modded it for less money then a stock Everest 154". No warranty now, but haven't had any issues with it, either. Wifey likes it - that's all that matters.
