I will admit I have an Arai defiant-x that whistles a little and buffets way more because of the vents but down here in south florida the wind is more extreme since there is no real hills or forest to stop it from hitting you straight on. I think maybe after a while I can go get it tuned but at least on mine there is definitely something causing a high frequency buzz and odd behavior at higher speed that keeps me wary.In my opinion the engine will handle the kind of speeds Folo speaks of. I do not believe the engine screams at all, perhaps you have a helmet which whistles? Like you though, man, my head is wiggling around and it is very unpleasant. I have friends with faster machines. We depart at the same time, but I get there a little later than my pals. All those crotch and corner rockets, man, folks just pass on by. They walk over to see the head turning Beemer!
