Yes I have a 300ex that has a jet kit that's it. But my friend has rt100(dirtbike) stock and he saying he could beat me in a race is this ture. And if u know can you give me the top speeds of these things.

 

HELP SOME BODY PLEASE

 

I would say that you probably could beat him. I beat my friend who had a RT 180 with my Blaster which is stock engine wise and has 22 inch Bandit AT rear tires, which would slightly change the gearing over stock. So the think you will win.
