I'm not a 4 stroke fan I will admit, and got my first chance to ride one for a weekend a few weeks ago, it was a Doo 1200, Im not a big fan of their sound and even less of one driving one, the low tone growl gets annoying to me, rather have the whine of a 2 stroke. I will admit the low end torque was impressive but that's where it stopped, I'm certain either of my 800 2 strokes would easily take it, I also found the powerband far more exciting on my 800's than the 1200 4 stroke. Now I will admit, I have never driven a turbo except for years ago a 660 TT, and if I understand correctly they no longer use the 1200 motor but if I could say the one thing that the motor needed and would have made it more fun to drive would have been a turbo. Again, I'm not a fan of 4 stroke but if i was to ever own one I would definitely make sure it was a turbo.
