Re: What stops you from using dirt-bike engines?
Big motor.... better have even bigger brakes
right now I have a ktm 250cc and a honda 125cc dirt bike motors and I will not use either of them in a bicycle frame as the frames will NOT hold up under that amount of power. People break bicycle frames with Just a 48cc 2stroke Ht. What do you think a 250cc 2stroke would do to the same frame?

Learn to do it right or how to fix it later, quicker to do it right the first time.
