Buying my nephew a little bike for Christmas. I have narrowed it down to between the KLX110 of CRF70. My questions are: Is one faster than the other? More power? Does one require more, or less, maintenance than the other? He is short (11 years old) and thin. He has played around on four wheelers, but never a two wheeler. This will be a first bike and not a last. I know he will outgrow either machine, but this is a good starting place, I think. The 80's are a little tall for him and I want him to be able to ride - immediately! I know neither have a manual clutch, and that is ok: I will teach him later on how that works. Any suggestions and all answers would be highly appreciated. So, what do "yunz" think???
