Or at least looking for info on alternatives. My 10 year old son has been riding since age 7 and has worked his way through an old school Honda XR75 and has now outgrown his CRF100F. The obvious progression now would be to a CRF150F but his riding skills are probably beyond it's "gentle" suspension and throttle. We considered a CRF150R but we don't want a red sticker bike. He is 5 foot and 90 pounds and currently jumps and wheelies as best he can with the 100F. What does Yamaha have that we should look at? Our target would be 5 year old +/- used bike in the $1500 range. Thanks!
