    Has anyone tried these? They are supposed to reduce head buffeting.

    I dunno...seems like snake-oil gimmickery to me, but I guess it's a cheap experiment.

    Interesting product. The science behind it is sound. Of course it does look a little silly and can be recreated by using double stick tape and a strip of rubber.

    The key is disrupting air flow that "washes" over your helmet and "crashes" behind your head.

    Achieving good aerodynamics is an amazing art form. Even the smallest change can make a HUGE difference. Think about NASCAR. Short little strips of metal along the rooflines help keep those cars stable at 190mph. Without them the odds of keepin all four wheels pointed in the right direction going in and out of turns is pretty darn low!

    Now that I have a windshield I am getting some head buffeting. Not a lot, but enough to be annoying. I figure it would be a cheap experiment.

    Looks like the same principle as VG's (vortex generators) used on some airplane wings to disrupt or change airflow. They work on wings and "might" work on a helmet, but a head/helmet DOES NOT remain in a fixed position, relative to the wind.

    I think the science behind this product is correct .....but in practicality may not work.

    Yeah, the helmet is one part of the "bike" that is not in a fixed position, so I would imagine you getting a stiff neck trying to keep in that one spot that works for the strip. If you are looking for something to redirect the airflow or disrupt the turbulence like that, then you may be intersted in the Laminar Lip: laminarlip.com/howwork.php
    From scooters to tourers, I've heard good reviews about it from folks. Not on my list of pleasing aesthetics, but functional.

    The head buffeting may not be from air coming over the windshield and anything you add to your helmet (like the rumble strip) may not do a thing for it. In my case, all of the buffeting was coming from *under* the windshield. A set of Buck's lowers took care of that and I get no buffeting now, much less wind noise, and a much more enjoyable ride.

    Yea, I have considered that. I know I am getting considerable air flow from underneath. I already emailed Buck and he said his lowers will not work on the quick release mount. I also called Memphis Shades and they said they do not have lowers that will fit the 950.

    I would be interested if anyone does get this please post what you think of the results. I don't have a windshield nor plan on getting one. 90% of my driving is on the island and it's hot and I appreciate the wind. And my full coverage helmet has vents and seems aerodynamically smooth . Besides I like the lines of the bike with out a windshield.

    Too bad you can't test this stuff out before you buy it huh? I wish I had a short quick release windshield to test out. I am curious what the buffeting would be like on the short windshield.

    Any hardware store will sell rolls of adhesive weatherstrip for the cheap that you could use to test this out with.

    I had the stock (short) windshield on my tourer for a couple of months and would get an aggravating vibration on my shorty helmet at road speeds of 65 or higher. Got the medium windshield (20") yesterday and installed last night. Rode about 100 miles today and the vibration on the top of the helmet isn't as bad but now have more body wind that gets up under the helmet at 70 or so... Guess the next thing to try is without any windshield or getting some lowers to break up the air getting in from below now. That larger windshield adds some extra "plow" effect, too, which seems to be more subject to crosswinds and buffeting... Will have to see what effect the bigger windshield has on gas economy too. Had been getting 55-58 mph with stock w/s.

    Well....I often wear a Shoei 1/2 helmet with a brim attached, have a Yamaha OEM MEDIUM windshield, with Buck's Lowers (i'm 5'9") and I have ZERO vibration or buffeting of my helmet......but even before I installed the lowers I never had a problem with a buffeting helmet.

    So my guess is you helmet may not fit correctly, not tight enough, or not strapped down tight enough.......try a test with a different helmet.

    After I made the earlier post, I took the windshield completely off and went for a ride and it was actually comfortable - a lot of wind on the chest, but not as "busy" or turbulent as it gets with the w/s on while wearing my half helmet (a thehelmetsource.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=THS&Product_Code=Scorpion100Series). Then I put the w/s back on and tried a ride with my full-face HJC helmet and voila, very smooth. I guess the half helmet with the brim acts a bit like a parachute (even though the fit is tight).

    Bottom line: unless the windshield is noticeably too short, disturbing air turbulence always comes from beneath the windshield, not over it. In this situation, Rumble Strips would be minimally effective, at best. Only a good set of Lowers ("none" are better than Buck's) will eliminate this type of buffeting.

    If your windshield is too short, then other choices apply, such as those that have been mentioned, which includes a better helmet, one that can make a huge improvement all by itself.

    Seems to me that the 'ducktail' on Shoei X11s, R1000s and other ff helmets address the same perceived 'problem'!

    think ill try this idea and see if it works
