A cr 70 ?? thats a 2 stroke?? If it is a 2 stroke I would NOT get it for him, put him on a 4 stroke (power is more predictable), when I was 14 I had a cr80, so dont worry about outgrowing it.. I would recommend a 50cc 
For you .... The klr is a great bike for the dirt,street and touring but the honda is better in the dirt that the klr

Whatever that little sheep said is a damn lie !!
