The other day I was doing a wheelie. Did a pretty long one on pavement. When I finally set the front wheel down, the speedometer jumped from zero to 75mph. That seems like pretty rough treatment for the tire and possibly the frame. But probably not as bad as the abuse the bike would take on a rough trail or from a full on hard stop from speed. I was just thinking that if the front wheel folded under the frame when I set it down at that speed, it would probably hurt. Any opinions of the risk of any serious breakage to occur from repeated high speed wheelie landings?
