You mentioned your height but not your inseam, that will really determine how well you fit on the bike. There is a member on here who setup a KLX250S for his wife who is 5'0". That bike has more oomph and better road gearing than the Yamahas. It is taller at 34.7" seat height but if I'm not mistaken the XR is even taller. I put a 1" lowering link on my KLX and at 5'6" 30" inseam I am nearly flat footing it, it carries its weight well too if you do drop it, very easy to flip back upright.
That being said the XT225 was my first choice but none of the dealers around had any left and could not order anymore, they place their order in the winter and that's all they get for the year.
