I am in this huge debate as to whether I should get a WR426 or the YZ. I live in Salt Lake City, Utah so I end up riding tracks and gravel pits on the weekends. However, my brothers both ride big bore XR's(XR600R and XR650R), and when I ride with them we ride in the mountains and usually to Baja Mexico once a year. I am leaning towards to YZ for the power and weight. My question is will the YZ perform on tight mountain trails and will it be fast enough in the Baja? Help???
