Just want to put my two cents in for those interested.
I have one of the Polaris X2 that we bought about a year ago. It is a 500cc model with fuel injection.
We really like it. I am 6'3" and about 250, my wife rides with me and it has power to spare even going up some pretty good hills on our 20 acres.
Nice storage in the front and the little bed in the back tilts to dump stuff if you want. The rear seat folds up out of the tilt bed and allows the passenger to sit up a bit higher.
With all the snow we had this past winter I was truly amazed how this thing got around in it. It was unstoppable.
Best Regards,
James
