Re: honda cr80 engine
are you nuts? sure it would be bad ass, and it would be very fast.
but, how are you going to stop it?
bicycle brakes won't do it, so you'd have to modify motorcycle wheel drum brakes to it.(or disks).
and then there's the quality and strength of the bicycle frame.
bicycles were never meant to go that fast and withstand that much vibration.
a bicycle frame would eventually fail under all that power (but it would be fun as **** up to that point....lol)
