I currently own a rancher 420 which has been an excellant first quad. Im looking upsize and am looking at these choices; can-am outty 500 & 650xt, rubicon, and arctic cat 550 preferably the s model. I was going to include the grizzly 550 but some of my friends have yamaha products and I havent been too impressed with durability, not trying to start an arguement, just saying what ive seen. Just looking for pros and cons of each. Ive rode a rubicon before so I know what im getting there, but id just like to do a little exploring into those other two quads. The search feature will be my friend.
