I am looking at purchasing another ATV. Right now, I have a 2007 Yamaha Grizzley 450 Outdoorsman Edition and have completely fell in love with it. The next ATV I buy, though, is going to have to be used. Everywhere I have looked, I havnt been able to find any yamahas unless they were super old. My question is, Is there any major issues to deal with when buying brands like the Kawasaki, Suzuki, or Polaris? I have narrowed my searches to '06 Kawasaki Brute Force 650, '04 Suzuki Eiger 400, or an '04 Polaris Sportsman 700.

 

All the quads you mentioned are good quality quads. Most of the makers have worked the kinks out of their models and all have strengths and weaknesses. All have true 4wd. Kawasaki uses a little lever that you pull with a couple fingers from your left hand to lock it in. I think the Suzi uses an extra button. The Polaris uses just the AWD button and kicks it in as needed. It's seamless. Polaris is probably the plushest ride. Brute looks best in my mind. I would get the Polaris or Brute just to get a little extra power.

 

There are all kinds of quads that you are talking about on ebay, including Yamaha's.
