I know I'm gonna step on some hands, but when has that ever stopped me?
I am fairly sure that Polaris is Greek for "BIG POS". Sure they have some great "gizmos" and ride great, but that's about the extent of their desirability. I have a good friend that is a longtime (2nd generation) Honda dealer and they picked up Polaris at their dealership about 10 years ago. I asked him lastyear what the difference between the service life of Honda vs Polaris. He looked up at me and smiled sheepishly, "Like daylight and dark!!!" [:-]
The only Polaris I have seen that hasn't given any problems are a couple or Rangers my brother has. But they aren't used a terrible amount and aren't worked. He bought a 700 quad when they came out 2 years ago, needless to say he now has a King Quad this season. A buddy of ours bought that very 700 Polaris from the dealership I work at where it was traded in. Our buddy didn't keep it 2 months, burned up a tranny belt and caused other problems in that short time. It was replaced by a BadBoy Buggie!
The Kawasaki/Suzuki bikes seem to be MUCH better than they used to be. We also have a 650 Kawie in our club and it seems to be an excellent quad, EXTREMELY quiet. I can hear the tranny whine over the engine at 400yds. But if I didn't have my trusty ol Honda (mines the "baby" in the club now, a 98 300 4x4 Fourtrax that I refuse to get rid of!) I would certainly have a Yammie. Probably a Kodiak, I just don't see the need for the weight, size and expense of the Grizzly. But I have gotten away from using a quad anyway if I can help it. I have an Outback ESV from Ricks ESV. Electric carts are MUCH more hunter friendly IMHO.
Good luck on whatever you choose,
