I believe the bike you see atop is not just a piece of art, it does have wheels that grind and when you storm through on such things, even the ghosts (forget humans) are bound to turn their heads. With all those blood stained carcasses glued to the fuel tank, the ghosts even might want to hitch a ride and invite you as the patron of their next Halloween party. Since the Blue Flame Alley has done all the customization to make the bike look the way it does, we are positive, that the ghosts are in for a prank!
