Yeah, that is a good point, I only let my son ride his on mostly flat ground.

 

How about an older one? I put my son on an Yamaha Zinger with a PW 50 motor in it when he was two. (his choice not mine) It had a twist throttle and I just kept the screw in it and at first would have to push him to get going and could walk beside him. He started racing at 3 and is now six and rides very well. What I liked about the Zinger was its size. A little longer and wider but lower than a lot of the current 50s out there. Just a thought and however you go just make sure they have the proper gear on.

 

I HAVE A QUESTION I BOUGHT MY BOYS A 90CC SUNL.II AM HAVING A PROBLEM WITH IT I WHEN THEY PUSH THE LEVER ON THE HANDLE TO MAKE IT GO IT MOVE A LITTLE THEN STOP WHAT CAN BE THE PROBLEM I NEED SOME SERIOUS HELP.
