Hello, Im looking for my son to take the class for the kids at this season opener, I have several dirt bikes but nothing with supermoto wheels, he is riding right now a KLX140L and a KX80 (Too big for him still). but also have a TTR50, CRF70F and a KTM 65SX. but last season he saw some kids riding on the track and he wants to try it. before I go and spend some money< I want to see if there is a bike I can rent for him to try it out, or If anybody have something for cheap. or maybe some supermoto wheels for any of the above bikes. or does it have to be specific size bikes for him to do the trackday on this coming Feb 13th season? he is going to turn 11yo this Feb 15th so I wanted to let him try it.

Any guidance would be appreciated.

Marco
