I think they look awesome. The running boards were improved. Pull rope in the center might be cool. Handlebars adjust way taller. I am 6' 1 and I would ride it all the way down. Goggle warmer in front of bars is cool. The tunnels look longer since they moved the rear bracket forward 3 inches. I liked the storage on the 10-11 seats. That is gone. They make a bag that looks decent. Won't hold what the seats did. I guess it is another way to get more money out of you. Didn't realize the oil reservoir is part of the chaincase. No more tunnel dump exhaust unless bd redesigns a new cover. They seem like they are shy on hood venting. Wish they would have changed handle bar controls. If you liked the m, and these were the same weight, I would think you would like these better. Just hope you don't have to change plugs. Fun enough on my 09. Not sure how they will handle when that tall spindle is stuffed into a steep sidehill. Not sure what everyone is worrying about on the a arms. If you run a tree on the inside of the ski on any of them there is pretty good odds you might wreck something. As far as the 1100 turbo goes, it felt like a tank to me. I was told they are 100 pounds heavier than the m8. If you were coming from a nytro and had to have a 4 I bet you would think they are awesome. Been there and done that. Not going back. Turbo 2 stroke is where it's at for me. Not a tree sled with all that front end weight. They look awesome. Wouldn't be agains't riding one. 99% sure I am buying a pro. If they won't let you ride them I will have to find out next season if i'm sorry or not.
