I'm all for having fun and maybe bending the rules a little, but those guys are just idiots. Way to bring unwanted attention to the rest of us.
It's usually the same group of people. Buy a bike, ride like an idiot for year or two, then they sell the bike cause of all the fines, insurance hikes or wrecks. See it every 2-3 years, faces change but it's the same story.
