Arai XD-4 Diamante Helmet

The Arai XD4 is world renowned for being the one of the best ADV touring helmets on the market and one of the few that achieves a Snell M2010 safety rating. The XD4 incorporates all of the same great qualities found in Arai's other helmets including the comfort liner and cheek pads that feature 5mm peel-away pads that allow riders to tailor the fit. The shell of the XD4 has also been aerodynamically tuned and, in concert with the removable floating peak visor, funnels air into the redesigned vents, improving overall ventilation and mitigating buffeting at speed. 

The XD-4 is the helmet of choice for many hardcore ADV enthusiasts and sets an industry standard for comfort, quality and safety.

Features:

  • Comfort headliner, with micro fitting 5mm peel away temple pads
  • Fully removable/replaceable/washable Interior: Comfort head liner, Cheek pads, Chinstrap covers
  • Dry-Cool technology keeps you dry and cool for greater comfort
  • Patent pending, FCS (Facial Contour Support) cheek pad design, also with a 5mm peel away micro fit feature
  • Improved shell shape for better aerodynamic stability at higher street speeds
  • Exhaust ports added to the top diffuser vents
  • Chin vent with more intake ports
  • Larger sculpted side cowl vents improve ventilation
  • Snell M2010 approved

Great Helmet
First, I ride a 2013 BMW F800 GS (I also have a Ducati Streetfighter and an Arai RX-Q, see my comments below) with a Touratech touring windscreen which is approx. 4” taller than the OEM screen. I am 6’0” tall but wear 30” inseam pants which makes me slightly more “top high” from the waist up. This helmet is for on-road-off-road use on the BMW.

My major concern before purchasing was wind noise but my experience has been that the bike, windscreen, and my body height is more of a factor than the helmet. My normal riding position on the BMW puts me just inside the turbulence zone of the air going over the windscreen. If I stand up slightly (+3”) on the pegs it puts my head into the relatively smooth air coming over the screen. If I do a super-bike tuck or lean forward lowering my position I get completely behind the screen with 95% of the air blocked. My other helmet, for riding on the Ducati Streetfigther, is an Arai RX-Q. The Streetfighter has ZERO wind protection and the RX-Q is quite tolerable for noise up to freeway speeds and no ear protection. The RX-Q on the BMW is noisy from about 30 mph up. The XD-4 is almost exactly the same, with the turbulence causing a general rumbling noise in both helmets. With either helmet if I stand up on the BMW into the direct air the noise level drops. If I lean forward behind the screen they both are very quiet. So for ME, on the BMW, with this particular setup, the XD-4 behaves noise-wise very closely to the RX-Q (which I find very tolerable). BTW, this particular windscreen setup while not perfect is a good compromise, it blocks the blast of air on your chest and doesn’t intrude on forward visibility.

Some other comments after about 2k miles and a couple of long trips ...
On a March three desert tour in Calif. with temps in the 90’s I found the ventilation to be excellent, noticeably better than my RX-Q. However, on very cold mornings going over mountain passes the more open neck area of the XD-4 lets in more air than the RX-Q. I end up putting on my Klim neck gaiter sooner than with my RX-Q.
I wear prescription glasses and purchased Scott OTG goggles primarily for low speed, hot weather, off road travel. The goggles just barely fit inside the face opening of the XD-4 and require a bit of fiddling to get over the glasses but inside the face opening. Other brands/types of OTG goggles may or may not fit. Obviously the airflow with the shield up and goggles on is even better.
The XD-4 has very good peripheral vision, but obviously not with goggles on.
On the desert trip and over a series of days of high winds the helmet developed, depending on wind direction/angle to the helmet, a very loud low frequency humming/buzzing noise. It got to be really annoying. I discovered that the screws holding the visor on the helmet had become slightly loose, snugging them up tight made the problem go away.

Summary. A great helmet for what it is designed to do with amazingly few downsides when compared to its all-pavement cousin the RX-Q. A bit pricey but worth it. I would buy another. Attached "selfie" photo gives an idea of the close fit with OTG goggles on.

Just a great helmet.
This is my 3rd Arai helmet & they just keep getting better. I read some reviews on other helmets that had more features but I decided on an Arai because there a great wearing solid product you know it holds up. The liner & shape in the the new XD4 is a great fit & quiet couldn't be happier with the helmet.

One year of ownership, still looks like new.
Living in San Diego, I commute solely on a motorcycle and love the Arai XD4 helmet. After 52 weeks of close to daily use, the helmet is still extremely comfortable and shiny with minimal upkeep. It is very easy to remove the internal liners to clean. The fit and finish are superb and the airflow is excellent without being noisy. The helmet is very stable at higher speeds. A bluetooth setup easily fits as well with the speakers snugly fitting in the cheekpads. The only issue is if you turn your head too far to the side at speed there is a whistling sound.

Great helmet and stylish
Never own a helmet with a peak, and was worried I may need to take the peak off. End up, the peak does not have any wind effect on my FJR1300 with the windshield. At highway speed, I did not feel any different between my last RX-Q and this XD4. The peak also provide the extra sun protection when I am heading into the sun. And the large open eye pot make me feel I am wearing an open face with has the full face protection.

It's very comfortable and the ability to remove 5mm of padding made it even better as it was a little tight on the cheeks. Air flow is great, very stylish. Just a really nice helmet and worth the money. I wish the Arai logos were a little smaller though.

Nice Helmet
Started out with a cheaper dual sport helmet and after loosing the screw that held on the visor on a long ride decided it was time to get serious about my riding. So far, I would say it is a very well built helmet and very comfortable. If I have a complaint, it is that when the visor is up it is still very noticeable at the top of my line of sight almost distracting (might just need some time to adjust to the new style). The venting is good and I'm looking forward to some summer riding to really see how well it all works. Overall I would recommend this helmet and I am glad I got it. As always shipping was quick and painless and the video review sealed the deal for me.

Great helmet.
Solid helmet. A bit noisy and has drag going over 60,but it breathes and is comfortable (even with Houston's humidity). I would recommend it. Fit is snug, as it should be. Make sure to know your size.

Arai quality, what else needs to be said?
this is my 4th Arai, and coming off the back of an XD3, some of the new features appear to be quite nice. I like the larger buttons for the top intakes, and the addition of the brow vents to the line. Fit is the same as the XD3, and the metal flake in the black helps the lid look extra pretty :D It's pretty much everything I've come to expect from Arai, and if it fits your head shape and like the style, I absolutely recommend it.
