Three and hoping no more. First was in the 80's on my 74 Honda 750. Went down in a corner in the rain and walked away with no wounds. ATGATT. Second was in the mid 90's on my YZ125. To high and to fast. One broken mirror and brake lever. The human was not made to fly without some kind of flight aid. Last year breaking in some new rubber on my F650GS I got to high on the side and laid it down. One broken mirror and one broken rib. Down one good pair of Redwing boots and one good jacket. Pants lived to ride again. Shit Happens fast. ATGATT is all I can say.
