We live down the street from a biker club clubhouse. Even one of them riding by wakes us up (we'll often hear them well after midnight), scares our cats, and sometimes sets off car alarms. My faith in the police ever doing anything about this is effectively nil.

I, too, am not a motorcycle hater. While I don't own one, I'm licensed to operate one, and have several friends who are avid riders. They have stock, quiet exhaust on their bikes, like normal people who actually care about people around them.
