I have long been a great fan of the xr600r, especially for riding the old mine roads in Arizona. Tons of torque, and air-cooled. Yet, of all the XRs, I see relatively few posts on this bike. Much more on the XLs and the xr650 and xr400. To me, the xr600 is one of the least appreciated bikes in the field. I've been to Baja three times. Twice on an xr600 and once on an xr400. (I own both models). The 600 was tons more fun for this kind of riding. What is the consensus — has the xr650 simply made the xr600 obsolete?
