Oversized throwing star?

I'd like to see the M/C that departed from.

Cuz ya gots ta wonder HOW the rider of the machine that lost the sprocket made out!

RIDE SAFE.
And you have to wonder how it got airborne.
Sprocket will be between the swingarm and wheel. Not only did the wheel have to come off the bike but then the sprocket had to unbolt iself.
My paranoid little brain wonders if the sprocket was dropped from another moving vehicle with malice aforethought
