My son is outgrowing his TTR-90, he pushes the bike so that the pegs touch the ground, I fear he may hurt his feet. He's almost 10, so anything taller than small wheel YZ85 is too much. The TTR-125 does not really deliver the power nor the suspension and it is even heavier than YZ85. I would like to stay with a 4-stroke though, and blue is our color, any suggestions? Thankful for your comments.
