used dual sport bikes can be found pretty cheap, but i think you will find the amount of fun you will have riding a motorcycle will increase 10 fold. small, light and don't have to worry about keeping it clean. you will find that you can explore places that you would never find on a big street bike.
i just sold a dr350 cuz i finally got off my butt and went thru the hassle of plating this beast..
ktm 300mxc! not the best choice for a dual sport bike, but is way light, great suspension/brakes. i can really root around some stuff now and not screw my back up if i gotta pick it up a time or two. and i love two strokes! most people would disagree with me on the choice of a two stroke.. but i believe most people are panty waiste nancy boys that gotta have the latest greatest four strokes with crack pipes to have fun... not me.
