Why do some bikers were 1 spur?

Answer 1

The myth supposedly began back in the days of the American Calvary. When a soldier would die, after his burial his comrades would take his boots and face them backwards in the stirrups of the saddle on his horse. They would then ride away wearing only one spur out of respect for the fallen soldier. The motorcycling community has adopted this same symbol of honor. When you see a biker wearing one spur they are honoring brothers and sisters who have died chasing the wind.
