It's not the motorcycle itself making noise. It's wind noise.

  Source? At highway speeds motorcycle wind noise is nowhere close to 100db. Are you talking about high speed motorcycle racing or something?

    At highway speed here in France, (110-130 km/hr), the wind noise is sufficient to cause tinnitus for me, if I'm not wearing ear protection under my helmet. The bike style is a factor - my touring bike has a movable windshield that can push the airflow above my head, but the wind noise from the daily bike, with a tiny windshield, is like sticking your head out the window of a moving car.

    According to this article, the source is from an OSHA study. I can’t find the study at the moment. https://www.hear-it.org/motorcycles-hazardous-to-your-hearing https://www.hear-it.org/motorcycles-hazardous-to-your-hearin...
