RE: Quads for hunting
I have a 2003 Bombardier (Can-Am) Outlander 400 and love it, plenty of power and keeps up with the 500 class.
Their new models are EFI and tend to have the most power in each of their classes no matter what size you select.
My buddy have the AC 650 and loves it.
However, I just read and article (for what it's worth) on a shoot out (700-800 class) and they narrowed it down to 3 finalist...
Yamaha won the all around and got rave reviews with the "power steering".
My buddy's Dad has a 2004-660 and loved it, and he just upgraded to the latest Grizzly and say's it's way better than his 1st.
Suzuki - Was the best value.
Can-Am (Bombardier) was the most powerful by far, but the most expensive!
