go with the cat, i have a 400 and have ridden trails with polaris's a predator, 500, and 600, when it came to the rough stuff i was out of it first, even had to haul out my uncle, only thing is the top speed, even so i maxed out my 400 to 55 on a flat asphalt road

 

i know they are made in austria but i believe the motors are built in the states but they are pretty sweet i would end up killing myself if i bought one though
