On average, the engine noise from a motorcycle hovers around 90 decibels (dB). However, many bikes produce noises in excess of 100 dB—a level high enough to require ear protection in U.S. workplaces. Excessive engine noise is just one of many factors that can lead to hearing loss in motorcyclists, including: Open ears.
Are motorcycles naturally loud?

Can I make my motorcycle quieter?
If your bike has a dual exhaust system, we suggest that you install cross pipes. These tend to do a great job of suppressing the noise by simply mixing the exhaust plus sound coming from the two systems. You can choose other pipe options such as the y-pipe and h-pipe designs.
Why are motorcycles so fast?
Motorcycles are faster than cars on average due to their high power-to-weight ratio and their small profile which results in less wind resistance and a low drag coefficient. Due to their lightweight, motorcycles also have less momentum at the same speed that a car is travelling, which makes accelerating more effective.
