I don't have much to brag about my firm athletic ass, but I DO drive a XR250 dual sport motor cycle. My girlfriend drives an NX250 dual sport. Mine gets 65mpg, her 75mpg. They were both under $1000 used.

There are many great dual sports to be had out there for around a grand or so. Search: klr250, NX250, XR250 XL250, TW200, ect...

With a dual sport bike, you can get off the road and camp where ever you want. It's very nice to have offroad capability as a climber ya know? With a dual sport, you don't even need a road or a trail even. As long as your handlebars fit between the trees, you're good to go!

I think everyone capable of driving one, should own a motorcycle/dualsport. One nice days, you can leave your car at home and save a ton on gas. I have an hour commute to and from work every day. My truck costs $15 a day, my bike costs $4 a day. My bike saves me $55 a week in gas! And on top of it all, it's way better for the environment.
Consider a small motorcycle man, and if you have any questions about them, PM me.
