I bought one about 3 weeks ago... I absolutely love it. It has it's problems, like any new bike, but once you feel the power of it you'll look something like this :--)
The only problem I have had with mine I had Saturday night... . I dipped into a rut and bent the tie rod... . I have ordered a beefed up set of aftermarkets for $70, and shouldn't have any problems.
Some of the other "common" problems are a low end miss-Dealer should fix before you buy IF it has the miss, mine did not... Anyway, it has the miss because the front carb is lean, causing a slight stumble in the low RPMs, easily fixed with DynoJet Jet Kit, or Carb needle replacemnt.
There is also a recall on the A-Arm bolts, I did not have this problem... . This was a problem mainly with the "early run" Brutes...
I put on 27" ITP 589's and it will still power wheelie from a small roll :-laf
After putting on the tires, I measured and the clearance jumped up to 13. 25" !!
As for the handling... A lot of people think it is "tippy", I couldn't disagree more. From the first time I rode this thing I have never felt more stable... Then with the wider tires, I don't even worry about it.
BTW... I sold my 03 Polaris Carb 700 Twin... I don't regret it one bit... I know it's not the EFI like you are looking at, but I liked my Polaris, just wanted more power... . AND I GOT IT :-laf
Hope this helps
