Kids do not need more power when they are learning to ride. My 11.5 YO has made a great transition from her '03 XR 70 (auto) to the manual clutch & trans. XR 80, and is eager to earn a TTR 125 so she can have a blue bike. She is ChadFreak22, after all! I am a Yamaha fan, but I believe Honda's small bike selection is better suited to learning, young riders. :boss:
If things go well, I suggest you start looking for a CRF/XR (same bike) soon because you don't stumble on a great deal like you got on the CRF 70 everyday. :cool:
One complaint, though, of the XR/CRF series, is that the 100 has one of the stiffest clutch pull of any small or even mid-size bike I know of, even though it is similar in every way to the 80. My 14 YO has noticed that both our CRF150 and my YZ125 clutches pull easier than the 100! (Yes, I have lubricated every pivot point and the cable)
