I got to take a friend's XR650 dual sport for a spin today, and I have to say even with knobbies on it, it still railed. The thing only stepped out once on me and it was on cold tires and late braking. It's a 94 or 95 model and had 1815 miles on it, when I brought it back it had 1860 on it
Only bad thing of the day was going down a dirt road that was freshly graded and loose, front end tucked, I dropped a leg, leg caught, felt like it ripped it off. That wouldn't be that bad but it was the leg I messed up in my wreck, but hell, I was riding who gives a shit
I definately have motard fever now, dr400sm here I come
