There is a slight drone, but mainly seems to be when going up hill in the 65-70 range, slower or faster and your pretty much good. You can hear it, but its not annoyingly loud.
the drone comes in and out depending on how much throttle your giving, you ease up a little and the whole sound dissapears, give it a some gas and its back
