How loud is a yz125?

The Yamaha YZ125 typically produces noise levels around 85 to 95 decibels when revved at full throttle. This level of sound can vary depending on factors such as exhaust modifications and the condition of the bike. For comparison, 85 decibels is roughly equivalent to heavy traffic noise, while 95 decibels is comparable to a lawnmower. It's important to note that prolonged exposure to sounds above 85 decibels can lead to hearing damage.
