I am trying to adjust to my XR600R, but the one area I am really strugling with is downhills, especially when rocks or anything mildly slick is involved. I live in Colorado, so I run into these conditions at regular intervals...I am starting to look pretty battered at this point. I feel as though there isn't enough brake to slow the beast down. I am also unable to get the bike to track in a straight line downhill. I always wind up sliding the rear out and to my right, which always puts me completely out of position for any switchbacks. While my rear tire isn't great, it should be able to grip much better than it is now. I am not just laying on the rear brake here. I am wondering if I am in the wrong position on the bike or am unable to preload the suspension enough or what??? I am getting tired of falling though. I haven't fallen this much in years. Any advice on slowing the beast down on this kind of terrain?
