Buffeting and wind noise on my helmet was a problem on my Burgman 650, a Laminar Lip helped a little bit but not much. Now on my 650GT the buffeting was still a problem, so I added a cheap ($30) extension. It didn't even have a brand. A five-minute job to attach it, with its feeble looking clamps, to the top edge of the windscreen. It works brilliantly! Except for long rides I no longer bother with earplugs. The extension itself is only about a foot wide and 4" high, and sits near the top of the stock windscreen, about 2" out from it - that is adjustable. It interferes slightly with my line of sight, but really no more than the laminar lip did on my previous bike, and this was a fraction of the cost. I still can hardly believe how effective this thing is.
