Imagine sitting on your porch, some hundred feet or so away from the street. A regular motorbike passing might clock in a good 70dB of noise on a decibel meter. You can easily talk over that. A two-stroke enduro bike with an illegal exhaust, however, can put out over 110dB in the same setting. That is a 10,000 times more intense sound.
