1. I have probably the least amount of experience possible to have. I'm not even particularly good at riding a bicycle, like, on the road. If there was a way to have negative-years of trail riding, I'd be a pretty good candidate. 2. That said, I catch on pretty quick, especially where engines are concerned, so I'm really super-not-afraid of getting something that might be considered "too much for me," unless it's going to literally kill me the first time I touch the throttle. I'd like to be able to grow into this bike and take it long distances and go fast and jump over long, long series of tractor trailers and play moto-polo and whatever else it is that people eventually learn how to do on dual-sport bikes. 3. I'm not a little person. 6'2", 210-ish pounds, relatively good shape. Planning on using it most often to commute to and from work (about 20 miles round trip), but most importantly to ride whatever trails exist in New Mexico (lots of dirt roads at first, but down the line hopefully some mountains, rocks, etc. I don't really know, I'm new here). 4. Price isn't exactly a killer, but cheaper is better. If I can get away with something under 5k, I'm happy -- if it's under 4k, that's better. Totally buying used. So, all that considered, here's where I stand. I've done some research online, which has been largely hampered because I'm dumb and don't know what I'm talking about. Basically I've pretty much gathered that I should start small -- but I've also gathered that if I start TOO small I'm gonna be clipping along at a road-rage-inducing 45mph every morning and afternoon. My first instinct was to jump up to a XR650. I sat on one and felt like I could probably handle it, but then I realized those sounded remarkably like famous last words. I started looking around online for something in the 450 range, and from reading around here I think maybe I'm finally on to something. So, anybody have buying tips for the dumb newbie?
