I bought a street-legal XR600 last year for dual sport riding in So. Oregon. It is sweet on twisty pavement and fire roads, and comfortable on long rides, but an overweight beast on technical woods trails (I ride hard, but only weigh 135 lbs). One option is to get a 2nd bike for trail riding, like a 200EXC. Another option is to sell the XR and buy a 520 EXC, get it licensed, hoping to have one bike that will work for dual sport roads and tight woods trails. Which of those options sounds most reasonable? Is there anything about my XR600 that the 520 wouldn't do as well or better? I've heard that a lot of pavement riding might be hard on the 520 transmission and that some DS riders install the LC4 rear wheel hub for the cush drive. I'd also need a bigger gas tank than the EXC tank, and a seat I could actually sit on. Any other considerations? Thanks, Jimboe
