    Any Brits have an www.Airoh.com they'd like to comment on?

    They've received great reviews at www.webbikeworld.com . They're available via eBay here in the colony but I'm weighing the risks of buying and shipping one without having tried it on.

    Any comments concerning the Airoh helmet are appreciated.

    I am also cursed by the XD + 950 wind screen problem. But I fixed most of it.

    Better wind protection and buffeting:

    Also makes my silver XD more visible. But the Helmet Skin tends to flap in the wind. I stuck the single fuzzy side of Velcro on the inside of the skin to stiffen it up.

    When it comes down to a 3 hour freeway only ride at high speed, I just take the XD visor off.

    The peak looks cool but realastically the only benefit is being able to lower your head to get out of the sun for visability. A while back I tried a trick I learned here and it works pretty good. On a regular visor helmut simply instal a piece of black electrical tape across the top of the visor. Ducking your head a little in the sun is almost as good as the peak.

    My specs are very similar - 5 11
    03 Model with old style seat
    Arai XD helmet
    no earplugs

    I was riding my mates bike described above, and he had cut an almight hole in the screen - Naca duct style - and I was quite surprised that I could see clearly without vibration with the visor up up to 180km/h. I had sunglasses on, but this was unheard of for me previously on a stock screen.

    Heres what I did to cure my peak vibration on the Arai - 2 layers of glass fibre and a bit of resin - voila. I then rattle canned it black to blend in nicely.

    Well I aint Brit, though we were colonised like half the civilised world. Thank God Almighty, we are free! :D

    I tried an Airoh on for size, and the build quality is so laughable, its scary. It has the feel of a 5 year old bmw plastic helmet with foam in it. I mean, bmx. Sorry, that was a genuine freudian, and I thought I would leave it in for laughs.

    The airoh is the most inferior quality looking helmet I have ever laid eyes on. And... the visor was taken to a local optometrist who declared it unsafe and bad news for the eyes. The Arai XD came back with good marks btw.

    I put on the Touratech spoiler. Now it does not do that much, but I found what it did do was stop the high frequency vibration of my XD visor. But thats all it does. Small improvement so I kept it.

    +1 on that. I took a look at the Airoh and also the HJC, which is sold at a similar price - they're probably OK for short trips around town, but for serious riding I wouldn't even consider them. On one of them (HJC I think) the visor didn't even close flush to the helmet - there was a 5mm gap most of the way around it. It wouldn't be very nice if you had to spend a day riding in the rain wearing one of those!

    GoNow,
    Your solution looks good.I did a very similar job. I now use a C bailys 15 in with an enlargened (bent in ) naca duct with a deflector on the inside to channel the air above my head. It works great !!
    Although there are different ways to skin this cat,......I think from my experience and the NUMOROUS posts on the subject, the 2 most effective fixes are 1) let some air through a duct to break up the "dirty" air behind the screen and 2) direct air over your head.
    Hope this helps someone !

    I suffer with this too, don't think its been caused by bike riding, doctor says stress related.

    Riding bikes = less stress

    Therefore, it sounds like yours is bike related - your not riding enough...

    Rode about an hour today. Much better. Air coming over my little 'screenlet' is much cleaner. No turbulence. I am tempted to look into a Schuberth or some other helmet for long distance riding. :thumb

    i pretty much have the same problem.

    the ringing is bad and it's pretty much non stop even when i'm not riding now.

    i used to ride lots of long distance miles but avoid long trips now for the agony i would have to endure as a result.

    it sucks as i find the 950 very comfortable but the ringing is torture.

    i wore an XD for a while but found it to be punishing on the 950. let me say this, if you're riding the 950 at highway speeds with an XD and not wearing quality ear plugs you're going to be in for a rude awakening.

    i'm wearing the Shoei Hornet and it's much quieter though still not ideal. i wear my street helmet most days as it's just a better helmet for wind noise.

    so are they doing successful ear drum transplants yet? :bluduh

    fwiw, i've found the duke mirrors and acerbis handguard combination relieve a lot of the noise from buffeting, in addition to a naca duct or hacked off screen of course.

    Has anybody tried modifying the sides of the stock screen? It seems to me that lots of the turbulence is coming around the sides.:scratch
    Crank her up to about 80 and put your hand around the top, sides, in the mirror area, and the sides have all the turbulence.
    When I bought my 950 the guy had cut the screen, (actually a butcher job) way down and the airstream was naturally calmer than with the stocker I have on now. I like the protection of the stocker, but will be doing something with it.
    I agree that the mirrors have a part in this, but I'm thinking that a combination of shorter mirrors with some vertical slots cut in the sides may be worth trying.:scratch

    Here is mod I did, do not know if the mirrors helped with the noise but they sure work good at protecting you from brush and branches.

    I was thinking the same thing. The 950 screen is like a pole flowing through air or water. Much more air flows around the sides than over the top. The eddies it creates behind the screen, I feel, are vertical and move right and left instead of up and down.

    Here's my idea, just not sure how to implement it.

    In summary, create an air blanket along the rear vertical edges of the screen that prevents outside air from turning back into the screen to fill the pressure void.

    Cut holes in the bottom front of the screen and surround them with some kind of open hood. The hood helps scoop more air than just what flows over the holes.

    Behind the screen, using some smooth piping or shaped channel, direct the air to flow at the back vertical edge of each side of the screen.

    That directed air would help alleviate the vacuum at the reard edges and prevent the outside air from turning back and rushing to fill the void behind/inside the screen.

    The scoops I believe are necessary because they increase the volume of air inside the screen, and correspondingly, decrease the volume flowing over and outside the screen.

    .............A /
    ............A /
    .....A \___/
    ---->
    .....A ___
    .....A/.. /
    .......A /

    OR hood captures vertical flowing air (Air =A) instead of air flowing up and over
