I have an '86 DR200, and had a '90 XR200. The XR I had was the one with the higher seat hieght, before they changed the rear shock, etc. I am 5'7'', 185lbs. I thought my DR was heavy, til I got to riding the XR. The bike is heavy, especially for smaller women. I would consider a different bike really. Maybe a CRF150F or a smaller two-stroke, like the KX/RM 100. The KX, RM, and the SX even, can be modded to "tame" the hit, and be more trail freindly compared to the YZ or CR (although it can be done). I would try to stay away from real heavy bikes. If you can find one, lay it down, and have her try to pick it up. Or start it even. Mine sure was cold-blooded. The two-strokes are going to be different from what she's used to, but the wieght savings are substantial! To add some perspective, I moved up from a YZ80, so maybe the wieght is more noticable to me. I can definitly tell that the DR is lighter then the XR, maybe if only by a small number of pounds, but when you're laying on the ground with a bike on top of you, bike wieght becomes a real issue. Money is the only thing that is keeping me from getting something different, really. See if you can try some differents bikes out, but definitly keep your options open. At 5'2'' I guessing that she's about a hundred pounds, I wouldn't suggest getting a bike that's twice her wieght, ecpecially if she is a novice or beginner. Another plus of an 80/85/100cc bike, is when she moves up, the kids will have another bike to "fight over". Lol. Happy hunting, and I hope I was of some help.
