Arai XD-4 Helmet - Solid
Still a geat helmet!
I finally retired my original Aria XD from 2005. This one has several noticeable improvements. The shield stays up much better and the visor is more solid. The adjustable cheek pads was also a great improvement!

Since this is one of those "dual sport" type of helmets with a visor, those riding are at some point going to get on a highway and get up to highway speeds.
With that said...when riding down the freeway at 55-60 there is understandable wind noise. So to protect my hearing during sustained freeway riding, I run custom ear plugs. That cuts down the wind noise to almost nothing.
What was interesting is that without the wind noise I started noticing a low frequency hum...somewhat a throbbing hum. Could not figure out where that was coming from. I would bend over behind the windscreen and it would go away, get back in the airstream and it would return.
Eventually I realized that it was the visor that was vibrating and causing that throbbing hum. Reach up and grab the visor, the noise goes away. Then I started looking and you could actually see the visor vibrating. I then started reaching up and squeezing both sides of the visor with my hand and the vibration went away.
So, long story short...I started putting a fat rubber band around the visor to give it a bit of an "arc" and the problem goes away. Weird having a rubber band up there, but it works. Thought about getting a piece of aluminum, bending it in a slight arc and pop riveting that to the visor. Still might go that way.
I contacted Arai on their website...never heard a thing. All it would take to fix the problem would be to make the visor a little more beefy in that area and the vibration would stop.
Once lost, hearing usually does not return so it's important to protect that hearing at all costs. Constant wind noise will damage your hearing. At the very least wear disposable foam if traveling over an hour.
Hey Arai...fix this please.

XD-3 to XD-4 Upgrade
I love this helmet. I was sized and fitted with a small XD-3 from a store that didn't except returns. After an hour of riding it felt like a vice on my head. I looked up Arai's size chart and I should have been a medium. I also read reviews that you have to have a certain head shape for the XD-3 and that the XD-4's were shaped less narrow. The XD-4 fit is great and is very comfortable. I just rode for two full days without any discomfort. The only downside for the XD-4, which has been pointed out in other reviews is the low frequency vibration from the visor. It's disappointing coming from such a pricey helmet. I haven't done any research into how to fix this issue yet but taping a quarter underneath it seemed to help a little so maybe some more weight in the corners would do the trick.

Wow what a *helmet*! Best I've ever owned.
Although this helmet is aimed primarily at the off-road/dual-sport market, I still rate it as one of the top helmets for *any* purpose. It's the best helmet I've ever owned, even though I've had ones that are more expensive. The construction quality is superb and the styling is second to none. Even though I chose to buy the solid-color, high-vis model, it's available in a wide-variety of solid colors and attractive graphics.
Best of all, the air flow is much better than anything I've used. Even in hot weather, I'm getting superb cooling from the variety of vents.
I also have to say that this helmet is much better set up for protecting your mouth and chin, so if you *are* riding on the dirt and rocks, it's far superior to a regular street helmet.
As for the price: It's well worth it. As I said, I've had far more expensive helmets that weren't nearly as good. As a former instructor once told me: "Never spend more on a motorcycle helmet than you'd be willing to spend to replace your head."

I've owned five different Arai helmets and have had my head saved in several crashes on the asphalt and also in the dirt. I love my new XD4. IMO it is the best dual sport helmet on the market. It is comfy, light has very good aerodynamics and little buffeting at high speeds. I've had it now for about 2 months and don't have anything negative to say about it.

Fits great with super good airflow
I started with a less expensive helmet however it did not fit the shape of my head correctly and gave me headaches. This is a dream. Constructed well with great airflow, padding is excellent and no headaches. The shape seems to be a intermediate oval and fits perfectly. I like the adjust-ability of shield that I can just leave it cracked for airflow a little and it stays there. A bit of an investment but well worth it.

Good for round'er' heads with great peripheral view access
This is my 2nd Arai helmet. Pay the extra $$ to get a good helmet. My first one was retired 2.5 years ago after a delivery truck made an illegal turn in front of me. I woke up in the ER and spent a few day in the ICU. It was an earlier version of the XD model (don't remember which one) and it was worth it's weight in gold. The XD4 has good room for wider heads, and you can remove/replace some padding for extra space. The visor has the ability to hold in a slightly open position to vent fog (has enough tension to be opened to pretty much any position) and I feel safe in the helmet. We just put in the Sena 20 headset and there is plenty of room for the boomless mic and speakers, although the velcro does not hold well. The helmet also provides great visibility to the sides and you can remove the top shield if you plan on doing tarmac riding. Universal, great fit, great visibility, highly recommend the XD4.

wanna get 'all eyes on you'? get this helmet!
-true to size
-very comfortable and snug fit
-plenty of airflow to keep you cool (esp humid countries, e.g-singapore)
-to cut it short, Anthony explains it all in the video
-the chin strap is somewhat or rather pressing hard against my adam's apple even though I've adjusted to the best length but it's not so bad that I'm 'choking'
