Just did the back road up to Crown King, Arizona yesterday and my xx was awesome. In fact it made it through the ride better then I did.....LOL. For anyone that hasn't heard of it, it's essinatly 4x4 trail that has a lot of rocky and very technical spots. Just pull up "corwn king back road" on youtube and you will find a bunch of videos showing the terrain. It's funny because I was talking to my buddy that has a raptor 660 and he said he liked everything except for where it was really rocky, and for me it was the opposite. I got a little sick of pushing my xx through the long winding roads leading up to the trail, but once we hit the rocky stuff I was in heaven. So any of you AZ riders out there if you get a chance definatly do the Crown King run but just plan a full day to accomplish it.
