Okay, I don't watch much racing (at all) so I'm sure this will be a really stupid question.
The 125, 250, and 500cc classes...those aren't the actual CCs of the bikes they race are they?
I understand that the race bikes are WAY different that the street bikes, but still...a little 125 whipping around a track? All I think is "big pocketbike."
What is it that I don't get?
