In the interest of fairness, I certainly hope the local yokels also pull over the teenagers with the $5k worth of amps and speakers causing the sheetmetal of their cars to buzz (I love how these "audiophiles" spend thousands to crank it up, but not one penny to isolate/insulate the sheetmetal). I'm pretty certain the kids in this area are way above 90 dba.
Face it folks, bikers have brought this on themselves with years of abuse and the trend will be for more and more towns to follow suit. It's one thing for a single biker to blast through town rattling windows, but when large groups do it repetitively it's pretty easy to understand the locals getting a little pissed. Nothing I love more than a group of 10 or 20 closing a local bar and then blasting up and down main street to see if anyone is still asleep. Act like a bunch of juveniles, then cry when you get treated like one.
