What would cause a loud roaring noise. This is not wind whistle, but a roar like a jet engine.I had an Arai Quantum II that was unbearable. Switched to a Scorpion 700 and no problem. Test drove a Shark RSR2 and at above 40 the noise became very loud with the vents open. with vents closed it was much better. This was on a BMW RT with adjustable windscreen, No position would make the roar go away. When I rode the Shark on the naked SV650 it was much better and the vent position did not seem to matter. But above 60 the helmet shook distorting my vision. This makes me feel the helmet was too loose.

Would this cause the "roar"?

You're right, it was too loose and air was making it's way in the helmet. And of course, the faster you went the worse it got.

Agree w/ Sierra...not a big discussion thread.

Next time very slowly turn your head around while you're riding. If you aren't too abrupt, you'll be able to see the dragon that's flying behind you and roaring.

If you turn too quickly you'll scare him away and he'll hide in your exhaust can.

Could you have lost a sliding piece that controls the amout of air flowing out of your helmet. I lost one of those on my HJC and the roar was deafening.

If had dime for everytime that happened....

When I test rode my D675 there was high pitch whine, I thought it was my helmet, but it was just the sound of the D675.

Naked with no screen gives you clean air hitting your helmet. With a screen it can cause "dirty" air (turbulence) and affects how it hits your helmet.

I'm guessing the helmet was too big for you. The helmet needs to fit as tight as possible without causing hot spots of pain.

I find that most helmet noise comes from the chin adding a fabric chin curtain will make it go away

I have a new Scorpion EXO 700. When I first got it, I had a roaring wind noise that started at 35 mph. I removed a windscreen that I had mounted on the bike (the OEM fly screen is still on there) and the noise is now gone. The windscreen directed and concentrated the wind to the top of the helmet area, which then created the roaring noise. Much better now that the windscreen is off.

I have the same noise on my SV-S which drove me to earplugs. I think its more of the wind screen design of the bike and less helmet, which yours does sound too loose as already stated. I'd bet the side plates of the faceshield on the Arai's dont help either, similar to my Icon. Interesting note though, my friend's GSXR stock wind shield was whisper quiet and I only heard that swarm of angry wasp in the engine ;D

I was going to suggest the "tiger in the tank", but you might be too young to remember Enco gasoline... Their mascot was a tiger- a direct rip off of Tony the Tiger. They used to give away tiger tails to hang from your gas cap.

Wasn't that Esso ... which preceded Exxon?

IIRC Esso was a derivative of S.O. for Standard Oil

*insert rant about how valuable ear protection is*

also, it's the exxon tiger, for sure:

Do you, by chance, have a large animal, or even any tribal print, painted on your helmet? This is only one of many problems with such graphics, I'm afraid. Friends don't let friends partake in fads.

Back in the 40's thru the 60's, gasoline companies were regional- Standard oil in the midwest was American oil on the east coast, and became Amoco when they combined. Enco was in the midwest, Esso was west. I guess I forgot Exxon was the result. Shell I think is still Dutch, isn't it?

Had to do with monopolies... Rockefeller had some issues with it and set up Standard oil as multiple companies to avoid Congressional intervention, and the other oil companies followed suit.

A chin skirt and/or ear plugs do wonders...

With my AGV I only use earplugs on the highway for long rides... otherwise it is perfect... all helmets are going to have some wind noise...

From most reports I've hears HJC are one of the worst for noise and buffeting of the helmets...


Oh and here in canada... my dad used to tell me about tiger in the tank commercials that Esso had... but aren't Esso and Exxon the same company

I think in canada esso is owned by Imperial Oil but I thought they were owned by Exxon... or are under license by... something like that...
