Travis Pastrana i think is the best dirt bike rider he was the youngest rider ever to compete and win the motocross de nations (pretty much Olympics of MX) he was also the youngest rider to win a freestyle MX contest and won 5 or 6 contests running

The best dirt bike for a would be a Honda CRF 100 for a male and a CRF 70 for a girl. Of course the real size of the bike depends on the size and experience of the rider.
