This rider got lucky. Really lucky. Joshua Boyd was riding at a track day in England when the belly pan on the yellow ZX10R in front of him flew off and hit him right in the helmet, according to LaneSplitter. It knocked him unconscious immediately but luckily he stayed in the bike long enough until he slipped off into the grass.
If he would have stayed on the bike or fallen on the track, well, he might have had a different outcome. Luckily he walked away okay after he regained consciousness but it’s a good reminder that not all crashes are rider error and to make sure and check that your machine’s gear is always checked and in place.
