Bike Crank
Posted on Sunday, May 23, 2010 in Bike Parts
Are dirt bike crank fly wheels hollow on the newer machines to make them rev faster ?
They aren't hollow, but they make the ignition rotor very small and put it on the inside of the coils for exactly the reason you asked.
The first bike they did this with was the Honda 125 Elsinore in '73 and those motors did rev quicker than the old external rotor motors, beyond a doubt.
