Hi Guys, usually over in the DRZ forum. Anyhow, my son (9yrs) is getting too big for his XR 70 (3rd year on it), I'm looking for a used XR 100 for him. The TTR 125 is a little tall. Any problems with the newer XR models compaired to the CRF's. He is a mellow rider, so a CR 80/85 is out of the picture.
