I'm sure it's in mph. 180 kph would only be 111 mph, and he's definitely doing more than that. 65 in first is about right also. A friend of mine sent me a pic of a cyclist that wasn't so lucky. He was traveling "in excess of 100 mph" and was weaving in and out of traffic....misjudged and hit the back of a tractor-trailer. His helmet was imbedded in the trailer roll-up door, dragging his body for three miles before the truck stopped. (Driver was not aware the bike had hit him) The guys shoes and toes were burned off from the dragging. Broke his neck and killed him instantly. I rode street bikes for several years. You definitely have to be watching for the other guy. I did my share of crazy stunts when I was younger. Glad those days are over....
