Crf150f Weight limit?

I'm looking at 4 stoke bikes and this one looks like the one I want. I don't want it to bog down and stuff though. What's the limit for this bike, I weigh about 150lbs and am about 5' 8" and 18, is this bike okay for me. Not for racing, or jumping just riding around a field with a friend and going about 50 or 60 mph.
