My question is: Why would anyone want to go that fast on the street? I have been riding along at 75 to 80 in a car in the center lane of Interstate 95 and had two bikes pass me well in excess of the ton. What if I moved into the left lane to pass the car in front of me? I would not have had enough time to react to there unbelievable approach time. All I heard was the sound as they went by. I ride, but not that fast. My rule of thumb is to be safe not sorry.
