I keep thinking of trading my GT and RR for the 1250RS, so I'd have one bike that does it all. But these windscreen posts keep putting me off. I spent $$ trying to solve the wind problem on the GT, and have almost got it, but the bike is underpowered compared to the RS, though not of course to the RR! |

I went with Givi, and I’m happy with it. Looks a tad dorky, but in the raised position it does the job of blocking most of the wind noise and debris (dust/rain) at highway speeds. Don’t care for it raised for casual riding, but it offers more than the OEM windscreen. I’m a Notary Public. RESPECT MY AUTHORITY! |

Dr. John Kennedy, a researcher at Trinity College Dublin has authored several papers on helmet wind noise. His work has been experimental, so it extends the level of understanding. In any case, the relative position of the helmet and screen are critical as is the geometry at the chin of the helmet/rider.

All good points. I have always considered buffeting to be when the helmet is being jostled around by "dirty" air causing an irritating inconsistent roar. I'm one of those that generally prefers little to no windscreen (nice "clean" airflow) or a large one with lots of protection - no in between. |

Zitat von SkipH76 im Beitrag #39 I've often found that condition can be altered by changing jackets or wearing neck wrap/scarf. As an example, I have old Tourmaster Sonora Air jacket with a ridiculously large neck opening. On the RS with a large shield or the stock shield in the highest possible position, the collar and shoulders of that jacket will flap like crazy. However, my old (stiffer, non-mesh) AeroStich jacket doesn't. Wearing a neck wrap/scarf with the Tourmaster jacket yields the same effect. Just my experience....

Zitat von Mr. 36654 im Beitrag #38 Why are you baffled? One definition: "irregular oscillation caused by turbulence. So for me that means my head is being moved around, in a non uniform way, by the unstable airflow over and around my helmet. As to how you quantify it, I would say you know when it's "a lot of buffet" and when it's just "a little buffet". Not exactly science, but YOU know ... |

Zitat von Ray im Beitrag #41Zitat von Mr. 36654 im Beitrag #38 My technical background is in fluid dynamics, so terms like buffeting lead to other questions like........What's the mechanism causing the buffeting? Is the flow shed by the screen the source? Then, I should see movement of the screen and feel oscillation in bike. It's the "in the weeds" questions, like these, that pique my interest.
