What's this?

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.


  • 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

Arai XD-4 Diamante Helmet 4.7 5 286 286
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. May 10, 2016
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. May 3, 2016
Great Helmet at a great price this is the second one I have purchased, great all round helmet May 17, 2016
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. March 30, 2016
you get what you pay for best helmet so far. i had hjc before and stepped up to this. its like night and day March 29, 2016
Expensive, but great helmet I wanted to get a supermoto helmet that has superior protection. This definitely fits the bill, but is also one of the most expensive, if not the most expensive helmet in that category. You get what you pay for with this helmet, though: peace of mind that you have a helmet that passes Snell and DOT standards, a visor, and a face shield. This helmet has awesome features that make the airflow very adjustable. Watch the video on this site. I love that you can use goggles with this helmet with the face shield. I had been using an old dirtbike helmet and this thing is just not even in the same ballpark and I'm glad I made the jump. May 5, 2016
nice helmet I run a quick strap on mine for my goggles it would be nice if opening was bigger for goggles but works, the speakers for my radio are tight do to smaller ear cups but other than that great helmet . May 3, 2016
Not as revolutionary as I was expecting Let me first start by saying this helmet is great and it definitely feels like a lot of thought and engineering went into it. With that said the title says my feelings about this helmet, it wasn't like the jump from my first budget scorpion helmet back in the day to a "premium," Icon helmet rather it felt like just like another helmet that just worked. It was comfy right out the box and has hands down the best field of view out of any of my many helmets but thats petty much about it. Nothing about this helmet screams unique and special rather just get this with the expectation of getting a great looking and functional helmet that will protect you in a crash... if that doesn't get you I wouldn't recommend you spend as much as this helmet costs.... Honestly, I dont feel any safer in this helmet than I did in my Icon or even modern scorpion helmets. I am not a big fan of how the speakers sit in the helmet, they are very quiet and from what I gathered it because of how thick the cheekpads are. I definitely prefer my Variant speaker set up but you get used to it and deal .The anti fog system is an anomaly, fog will show up on the visor but it always quickly disappears so I guess its anti-fog.
