Arai XD-4 helmet whistling.

Hey everyone

I just brought a arai XD-4 adventure helmet, anyway I get it home take it for a ride and find that any speed over 40 it whistles like a vortex throwing ball thing. Rang arai got some recommendations and he said check for leaks around the visor and just locate the noise. The noise comes from the sun visor/peak of the helmet. I took it back after a week to shop I brought it off and I was told it was normal for a arai helmet to whistle. And she said to get use to it.
The thing that annoys me is the fact I brought a $800 dollar helmet that is worse than my old $200 dirt bike helmet.

So my question is does anyone else have a arai XD-4 and do they find they whistle? Not just wind noise, but whistle like one of those vortex throwing balls

MIne doesn't whistle, but apparenlty on some bikes the intake vents on the visor can whistle if left open . If closing them improves the whistle you cold consider using one of the xd 3 or older visors which didn't have the vents?

I've got one and can't report hearing any defined whistling noise. You do get your normal wind noise but that's about it. Overall I'm very happy with my Arai XD4. Any chance you can get it exchanged as defective? Would be happy to vouch for you that the whistling noise is not normal.

No whistling from outside, only from me inside because I am happy :) best helmet yet.
I'm sure you've tried placing your hands up around the visor to try & pin point the area making the noise?
I would also try another bike to check its not turbulence related from bike????

After that take it back and request trying another helmet.

Had the same problem. For me it was generated at the back of the peak (or tailing edge). I stuck a bit of foam (about 2-3mm thick) on the underside of the peak at the back to disturb the airflow and that has worked. When I get a chance I'll post a pic.

Ps - mIne did it standing, sitting and everything in between so I concluded it wasn't bike related

Mines heaps quieter than my Old XD3. Is the airflow coming off your bike causing it perhaps?

I've got one and it doesn't whistle. Like someione else has said, it may depend on air flow over the front of your bike and the direction it hits your helmet from. Mine's a lot quieter then the previous model.

Mines not whisling but found if i closed the brow vents in the visor the wind noise is alot less.

Mine does not whistle either, but it did when I broke one of the pinlock pins. Now has a piece of tape over the pinlock hole and problem gone.

why do lady parachutists wear parachute pants?
so they dont whistle on the way down

What tune is the helmet whistling? This is important, as different tunes signify different things.

For instance, if it's whistling Dixie you need to join the Rebels and get the confederate rockers on your jacket. If it's whistling I Should Be So Lucky, then wear a little skirt and go acting. If it's whistling like a kettle, bring a tea bag......you get the idea.

Good to see your taking this whistling issue seriously

I wonder if she has tried standing up?

Be really cool if it was the HarlemGlobetrotters theme!

My helmet used to whistle the Colonel Bogey March and for hours after riding all I wanted to do was build bridges out of sticks :eek1

I've got an Arai XD myself, but it doesn't (or won't :ddog) whistle.

I've had helmets that have made odd wind noises and such, but I just worked it out with a bit of trial and error. It's a fair question from the OP, to which I don't have a definitive answer, so I'll just ask silly questions instead. Am I normal?

My XD4 whistles a bit too, but I haven't had a chance to work out why.

Should just be a process of elimination. You could try closing the two litle vents on the top, just back behind the peak. If that isn't the problem either remove the peak and see how it goes or temporarily stuff a bit of foam rubber between the peak and the helmet.

I suspect the last one is the problem with mine, if so I will just experiment with some adhesive foam strips placed to break up the airflow a bit.

Cheers,

my 150 dollar fly trekker doesnt whistle
