We have some pretty tough, very steep terrain at our camp. We work our ATV's very hard to say the least. We use them for foodplots and pulling logs for firewood. So it has been a good test to see how they stand up against each other. What I have observed is that the Honda, Yamaha, Can Am, and Kawi have all performed very good. If I was looking for the best all around , I would probably go with Honda (even though I own a Yamaha and Kawi). One thing is for sure, I would not buy a Polaris. In our experience they have not held up well at all !
