My daughter has been on a quad since she was 4. We are excited that she is finally willing to try a bike. Last weekend we borrowed an xr100 for her to try. Seemed like a great fit, but husband thinks she will outgrow it too quick power-wise. We have a friend selling an xr150, and he thinks that might be a better choice. She is just shy of 5ft. and around 95 lbs. Your thoughts?
