I will be buying a Xxc in Sept mainly because I can get it in my truck. It will take a little moding but it will fit through the rear as does a RZR S. The main disadvantage I see is you loose a couple of inches ground clearance and two inches of travel. Since I will be using it mainly for sand clearance doesn't hurt and the lose of travel is just the price for convenience.
Most of trail here are in wood. I only do trail riding, no mud, sand or rocky terrain. We have small bridge with 68 inch width. Dealer will recieve Xxc at end of august, i will compare both model. For driving do you think with the xxc we have more chance to loose control at high speed in a curve because he have 60 inch?
