I have a 02 polaris sportsman 500 HO, To be honest I hate it. I had a 04 Arctic Cat 650v2 and loved it. It was done up and tons of power. I found the polaris is under powered in high and to slow in low. I shouldn't blame the bike but the last owner did zero maintenance on it and it is costing me a alot of $$$. I am going to get a new quad soon. I have it down to three.
2010 outlander 800 xtp- lots of $$$ and weak frame
2010 polaris 850xp EPS stealth black Bad luck with polaris and 4x4 working
2010 Arctic cat T-Cat, Test dove it and what a arm stretcher loved it.
I am more leaning towards the T-Cat then the 850xp
04 rancher AT ,love it!!!!! does what I need it to and more....if I get another someday may have to go with MORE POWER !!!!!! rancher is nice but bigger even sounds better..lol
