I took one to the knee on my old Valkyrie at about 40 mph. I can't imagine what 80 would do. On the bright side, it left a perfect impression in the tank that my knee would fit right in from there on out.
I hit the back brake a little too hard and slid into one sideways. We were looking into each others eyes.
The impact stoped me from falling over. I was on a Harley dresser.
The deer never missed a step, just ran faster and was gone before I could get my sh__t together.
I did find a few hairs in the hand grip.
Ohio is littered with road kills.
