it really depends on how well your bike is running the fastest I have seen one go is 70 mph
my friend had a speedometer and i was 5th gear tapped(pinned), and it said i was hitting 71.
about 80mph
YES! The only difference between a 250 and a 250f is that one is 2stroke and the other is a four stroke.
Yes, a YZ 250 is a 2 stroke, a YZ 250F is a 4 stroke.
