Used to ride bikes way back in my teens in the 80s, yz125 back then. Thinking about getting back into it and riding some of the backcountry trails and fire roads. I'm 6ft 195lbs but as I said I haven't spent any significant amount of time on a bike in years, would a 250 be fine? I am thinking of a used Yamaha WR250 or something similar.

Thoughts?
