Buffeting (Aeronautics) response of an aircraft structure to buffet, an irregular oscillation of the tail, therefore, with there being no windshield on my 2009 FLTRSE3 to speak of and the oscillation of air flow is not irregular nor is it unpredictable when you increase speed; the wind force against the rider will also naturally increase, this my friends is not true buffeting; whereas, if you do have a windshield and turbulence comes between you and your windshield while riding due to the angle, dimensions, poor design of the windshield and or the riders height, this to me fits the definition of buffeting which has been clearly described by many riders in past postings with legitimate windshields, that can by definition create buffeting.
To recap, to sit on a bike with no windshield (2009 FLTRSE3 windscreen / visor is as tall as the inner fairing) and accelerated; and not to anticipate force just isn't sensible, thus, not an irregular air flow, it is the expected outcome and I can't call that buffeting.
Again, just my.02
