Helmets-Buffeting
04/11/12 9:57 AM

With the thought already to buy a quality helmet as far as safety. My question leads me to head buffeting. I get tired and sore from the wind knocking my head around. Skim feading leads me to the thoughts , that some helmets significantly reduce this.
So what brands, models, and anything else to buy, to reduce this buffeting. I wear ear plugs for rides longer than 15 minutes,(basically more than a run to the corner store for groceries) so noise is not a primary concern, but the quieter the better still.



No officer, I am not riding too fast, I prefer to think of it as Flying low.

All I can say is that A Shoei RF-1100 is not quieter than an Icon Domain. Had a big heavy HJC and it was quieter. Rather have a light helmet that buffets a bit than a heavy helmet any day.

Thanks for the input Rook. How is your Shoei 1100 for bufetting?

Well...any helmet is gonna have buffeting because of the shape of the nose of the bike.The only way to reduce that...is...change your riding position at speed(I'm guessing that's when it's most pronounced)...OR...get an aftermarket screen that directs the flow up higher and over your helmet.But like Rook said...a lighter helmet will have a less amount of mass to be moved around...so the 'buffeting' is going to feel less...but it's still there.It's kind of a trade off really.A heavier lid will be less apt to get tossed around(considering you're not sitting directly in the windflow),but...as it does..it's gonna put more strain on your neck.A lighter lid will feel better over the long haul with windflow hitting it simply because it has less mass on your neck muscles.

I have a CF Vemar...it weighs 1300 grams.I have an Arai...it weighs...well...more for sure.I feel much better with my Vemar after a days riding than I do with that Arai...it's just the weight factor.They both will get buffeted somewhat.It's very minimal on my bike.Almost non-existent.It's really not the helmet..it's the way the wind is moving across the screen and such.Find your 'sweet spot' behind that screen...you'll see a big difference.Aerodynamics are like auto rear end spoilers...they don't do much UNTIL...you start to hit big speed.That's when you realize if they work or not.At 70 mph...a helmet's a helmet.

You shouldn't(IMO) be trying to sit bolt upright at 150 on your Ninja.Unless you like taking lots of aspirin and hot soaks for your neck.


I've got several screens of various configurations...and 3 quality helmets.I've tried about every setup you could think of to test buffeting and helmet reaction w/screen setup.NOTHING eliminates the windflow completely.What they do is move it either up or down as to where it hits the helmet in a 'normal' riding position.Tucked in...it really doesn't matter.But you don't ride tucked in everywhere.So you find a sweet spot for you,with the screen you feel works the best,and ride.IF you REALLY want a good windflow blocker...go with the Zero Gravity Touring Screen for the ZX14.That will significantly stop your buffeting issue almost 100%.At any speed.


If you're talking buffeting BEHIND a tractor-trailer...forget it.NOTHING will smooth that out...except PASSING!!!!!

Recently watched a documentary movie called Closer to the Edge about Isle of Man racers. They show the bikes up close. Noticed that a windscreen on Guy Martin's bike was not very aerodynamic looking. Not really. Instead of following the flow of the fairing, it bubbled way up. Looks as though it is designed to shoot the wind up away from a rider seated more upright. Works fine for a tuck too but not going to cut the wind as good as an OEM windscreen.

Thanks for the input Rook. How is your Shoei 1100 for bufetting?
Well, I have to admit that I may have been shooting my mouth off a bit....see, I am one of those riders that DOES ride tucked in--not all the time, but I will do it over 60 mph for 2 hours straight if it is cold or 70mph+ in any kind of weather. My head is pretty safe from buffetting. I notice my head bobble at times on a windy day with the RF-1100 but not any more than I would expect....every now and then like when the bike gets whipped around by strong winds.

Yes, it is gross. In a silly kind of way.

Buffeting... well, I don't have to worry about that anymore, at least.

For what it's worth..... I have an RF1100 and an MRA Sport Touring screen. I was having problems with helmet lift at speed. This screen isn't much larger than stock but has a lip at the top. Stopped the helmet lift and most of the buffetting. I'm 5'11.

For touring I have a Zero Gravity sport touring screen. It's very quiet and no buffet, but it's pretty big. I only use it for long rides.

Thanks Grn14, very well written. I will look into the zero gravity screen as well.

Thanks again Rook, nice answer to. I am not great at tucking in. ( read my back and body in general are trashed)
