Has anyone ridden fast and have there head start shaking? both of my helmets do this at speed, has anyone had the same thing happen and is there a way to prevent this? and is it a helmet problem or maybe I need to tuck in more. Mike

sounds like your helmet may be a size too big for your head....

Hey bob no it is not to big when I got it it was to tight for me and then formed to my head so I know it is not that, but thanks for the suggestion. Mike

Did you set up your suspension yet?

Perhaps an older or lower cost helmet with poor aerodynamics is your cause.(you do mean wind buffeting of your helmet as opposed to hi speed wobble don't you?)

Yes I mean helmet shake and Yes I also adjusted the suspension to my weight from the manual and the bike is running excellent, I have two helmets both mediums and one was real tight on my head and almost sent it back but both at high speed make my head go into a shake which is not good, maybe I need to get down lower in the crouch down position and that probably will work, or get a new helmet my good one does not say snell because it is not from this country but is ece r 22-05 and they might give me a hard time wearing it at the drag strip, so maybe I will get another helmet that is snell approved.

Maybe your helmet has too much wind resistance.

How did you know I wore that helmet, anyway will try my other helmet and get real low and fast, maybe I was not going fast enough to cut threw the wind. Mike

How much does your head weigh? Maybe your neck muscles are getting weak. To build your neck muscles try doing some laps in a pool with only moving your head for propulsion.

if you chose first class helmet is difficult that you get this trouble

a clear example are motogp driver helmet or superbike driver helmet, at more than 300 kmh no trouble .

you need to stay on this helmet category

Mike, I have a Nolan N-102C, haven't noticed any buffeting except in bad cross-winds.
It is a little noisier than my old N-100.

I like Nolan's Modulars.
Never go back to a helmet with D-rings

I have a Nolan N100 and N102 as well. I really like the modular helmets and Nolan is considered one of the strongest and safest of the modulars.

That being said I recently bought a Shoei TZ-R. OMG it's so much quieter than the Nolans and lighter as well.

Even though I miss the flip-up and sun visor on the N-102, I never wear anything but the Shoei now.

I am thinking of the scorpion exo 1000 but now I do not know? I tried again today and tucked in and hit like 130 and went upright to brake and thought my brains were coming out, this is not good, I have a tumor in my ear that makes me dizzy and this will make me even more dizzy, not a problem under 100 so I guess I need a aerodynamic helmet to cure this problem. I have a zox modular helmet with the flip down sun visor which I love and got it for 160.00 shipping included, the scorpion has the flip down visor and is snell approved, and I also have an Akuma stealth helmet that is ece approved and paid over 400.00 for that helmet and does this also, I would like high speed feed back on helmets and if anyone has gone this fast.

the best thing that you can do , is to go to 1 meeting of very friendly bikers and try to try their helmet ,

I search also many review but all say arai .

anyway as told you can see helmet model that use superbike and motogp or superstock driver , sure at 100% that all that helmet work with speed .

Definately sounds like a helmet issue...I had this with my Icon helment on my GSX-R600. Swithched to a Shoei X-11 and haven't had an issue with buffeting since.

I have a Shoei X-11 and I never have a problem with head shake. My favorite helmet is the Arai, but they discontinued the Signet series, which fit my grape best.

I have seen the Schuberth helmets, and those are really comfortable with very good aerodynamics. It is very hard to find them, though, as hardly anyone carries them.

Thanks Guys I will start looking for a new helmet, I also can rent a helmet at track day to make sure I get the right one.

Hwyranger I had a nice Schuberth modular helmet with the flip down sun visor and loved it, but now is missing parts and I can not get parts so needed a new helmet.

I bought a zox and it is modular and has the flip down visor like the Schuberth and cost me 160 including shipping and is a nice helmet but the slide to lower the sun visor is not as good as a lever.

I find this feature very good and when riding in the summer it can get dark with all the trees then it will be bright at some spots and you can quickly flip down the sun visor or up for the different conditions and love this feature.

regarding the visor , for aray suomy and shoei (i'm not sure) you can find light adaptive that really work , are also very fast in changing when you goes in the tunnel are expensive of course , on arai you talk about of 115 , 130 euro ..

like another not branded helmet , and you forget sunglasses or every other thing .

Mike:
Besides changing helmets take a look at different windscreens, laminar lips, etc. I always ride with a full face helmet and different bikes buffet my helmets in different ways. I find that you either need to have your helmet completely in the airstream or completely out of it in order to get the "smoothest ride". Of the three helmet brands I currently wear, the Scorpions are the most smooth and quiet. I ride a Ulysses, City X and an FJR 1300. My other helmets are an Arai RX7RR and a Shoei RF1000.

Mike - one thing I've done in the past for track days is snug my chinstrap tighter than I usually do. I've found that any bobble usually comes from the helmet lifting slightly, then moving around. Snug that SOB tight and see how she does.

Good to hear the reports on the Nolans, I've been thinking of getting one. Tried one on at Seminole when I was there and it fit nicely but didn't get a chance to ride with it. I like the features though (I have gaffers tape on the top corners of my visor to take the place of the Nolan sunshade - that low winter sun sucks).

I wear glasses with wire temples, so if I want a full-face, it HAS to be a modular.
I just can't get used to paddle temples, I've tried.

I put the old N-100 on yesterday to see if it was quieter.
Not appreciably, so it's back to the new N102, con mucho gusto.

Light adaptive visors? WHERE???? I want it I want it I want it...I hate trying to stuff sunglasses on inside my helmet and unless I have a bag on the bike for the extra face shield, its like I'm a kid again...be home before the street lights come on...

I would like to thank all you guys trying to help me.

I also were glasses and the Zox Modular helmet is hard to wear glasses with this helmet, I have seen helmets that have like holes to put the stems in them but do not know how this would work.

I also love the flip down visor and I think this i is perfect for sun and shade ridding, but the Zox helmet visor is hard to work and has a slide instead of a lever.

The Scorpion exo 1000 is the helmet I want to buy but now I am afraid of buying a expensive helmet only to have that cause head shake to, it is snell approved and has the flip down inner visor, but I need a helmet for the track.

I have an Akuma stealth helmet that cost me over 400.00 and I have tried to tighten the strap more to see if that worked and it did not.

I now have two new helmets, one for touring and is modular, and the Akuma that is really cool looking with the stealth bomber look and has a front map reading light and two rear red lights as the back vents that are painted like jet exhaust and is rated at ece r 22-05 but does not say snell, but is suppose to exceed snell standards, it is not snell approved because it is not made in this country.

I would like to know if tracks except a helmet with the ece R 22-05 ratings.

I also am going to get from www.saeng.com has some nice windshield stuff and they have this rubber edge that you can put on your windshield and it is suppose to break up the wind giving greater protection from the wind and rain, and have other things like wing tips.

I do not want to add anything extra to take away the looks of the bike so I will get the rubber edging from saeng and then will wait and see if I can find the right helmet for me, I really like the scorpion exo 1000 and will contact them and ask them about this problem.

I also will do some research on this problem and check out the helmets that you guys suggested.

Mike

Mike, let us know how that edging works.

I have looked at raising the screen like Bratmanrider, but haven't found a clean way to implement it.
Everything so far looks out of place, at least from the rider's POV.
