I have an 07klx250s and I love it! Commute to work 40 mins each way, longer on the way home when I'm riding the trails. I've ridden with faster riders on faster bikes (katooms in single track), and I can keep up, I just have to work a lot harder. Now I want to sell my street bike and buy a 650D/S probably japanese. I plan on keeping both D/S s the little one with knobbies and the bigger one with 50/50s on it.
