im wondering if the 09's have addressed the heat issue since the engine is totally difernt now. im guessing there wont be no where near the issues. but personally i will never know my self.

 

Not sure if they corrected the issue or not?
I talked to my Polaris dealer and this is what I took away from our conversation...
The 800HO had a quicker response time and also still allowed you to lift the front wheels up.
The 850 had a larger power curve seemed to want to go faster on the top end.
Polaris did make the comment that they have put more units out in the testing field along with more testing hours logged on the 850....

I am really satisfied with my choice.... until the 850 passes me on a frozen lake...
Who knows... We usually never get over 50 mph where we ride...
