dont have any high performance parts. but it goes 32mph. i dont really need to go that fast anyways. I also dont wana get stopped by the cops on it. I always find myself wanting to go offroad. so i am gunne put my engine on a off road deal.
If you want high top speed. i would highly recommend a street bike. like this. with less parts. (not heavy) but only if u feel really confident ur your work because you dont want to be racin around on a bike that may fall apart
