You're pretty light, so an xt250 might be ok for you. It all comes down to how much 50+ mph riding you're going to do on the bike. My 250 would go 55 with me on it (I weigh 150 lbs), but it was pushing it, I was uncomfortable, and there wasn't enough power left for emergency maneuvering at high speed.
I started 'dual sport' riding on a 250, because I didn't think I would want to ride it at 55-60 mph... but I was wrong. Within a year, I had ridden ALL of the trails and fire roads within range of a 250cc from my house. If I could do 55-60 mph on the highway for about an hour, I could reach 3 huge state forests, which I will probably never finish exploring. I'm glad I traded up to the 500, it opened up many more riding opportunities, because of where I live. The other plus of the 500 is the toque. Its a wheelie machine and is quite fun on twisty paved roads too. That being said, if I lived in off-road-heaven with nearly endless mile of trails starting at my doorstep, I would ride a 250.
My point is: a 250cc enduro bike is plenty for trail and dirt road riding. The question is: how far from home are the trails you want to explore?
If you decide that a 250 is right for you, mid to late 1980's Yamaha xt250's are dirt cheap these days. There are 3 NICE 1980's xt250's near me for $700-900.
Don't forget the xt200 or tw200 either, they are bullet proof bikes and is only a few horses down on the 250.
$1500-2000 is a fair price for a NICE xt500. Beaters (with titles) sell for ~$1000.
While the xt550 and 600 are nice, their dual carb setup is apparently temperamental and frustrating. I have no first hand experience with either though. For a 'way out on a trail in the middle of nowhere' bike, I like simple.
