Has anyone tried these bikes on a motocross track ? I may be using one for motocross riding now and then. I am interested in a TE450 for riding to work and back but mostly for trail and some moto. I already own a Yamaha 2-stroke motocrosser which I intend to keep but my daughter will be using it when she has time to ride with me. I am 5' 10", 150 lbs vet intermediate mx'er. Will this bike work for this purpose? How are the AMA dual sport rides? This would be another use maybe.
