Yamaha's TT-R125LE makes a perfect trail bike for kids and teens. The 19 and 16" wheels give this option a smoother ride over rocks and tree roots, while the low seat height and electric start help make it trail friendly in the event of a stall. The TT-R125LE will introduce your rider to a manual clutch as well, so being able to plant their feet if they suddenly stall is important.
