Exhaust sound look performance ?

[willtill]

What is the reason or cause for this drone? And do most bikes get it? I never heard of this before my F6B.

The best guesstimate IMHO is the way that the exhaust resonates through the F6B's cats and the baffles in the silencers. It's a harmonic issue with the way the gases pulsate as they make their way through the stock system; while at maintained certain speeds and acceleration.

Based upon demonstrated empirical evidence; the harmonics are further enhanced by type of helmet and selection of windshield; as well as rider's vertical positioning while on the bike. Many variables involved. One configuration normally is not applicable to others experiencing the cacophonous cacophony of noise and irritation to the aural senses.
