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

Arai XD-4 Diamante Helmet 4.7 5 280 280
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
A bit loud It is louder than I hoped but am currently using the 15mm cheek pads. Possibly quieter if I use the standard 20mm pads. March 22, 2016
Arai XD4 explore This is by far the highest quality (and most expensive) helmet I've owned yet. It feels well built, looks awesome, light weight and has great visibility. It is however the noisiest helmet I've owned; at highway speeds there is a lot more whistling and buffeting than I'd expect from a mid to high end helmet like this. As I mentioned visibility is great, but there is some distortion that you'll eventually get used to and even with all of the vents open it still fogs, which are the only reasons I gave it 4 stars instead of 5. Overall I'm very happy and would reccomend it. April 19, 2016
Isn't your head worth it? I've ridden touring and sport bikes throughout Asia. In Japan, Arai is what the majority of riders wear. I was steered towards Arai when an old crusty Japanese dude said to me: "baka jyanai ka? omae ha kodomo ga iru ken, kotsujikou shitara ichiban ii herumetto kaburanto..."-- google translate it. The XD4 is quiet and I really like the adjustable ear cushions. The fit all around your head feels really good- there is no space or gaps (I have an off shaped head). Spend the money on your head- better to have it and not need it, than to need it and not have it. Revzilla knows their stuff and have the best prices. April 19, 2016
Great lid Rode 700+ miles in it last week. Super comfortable if you're used to an Arai shape. Even after 10+ hours on the road it was fine. Open all the vents and it flows tons of air. Too early to tell how it'll be in the summer but it's a dramatic difference full open vs. full closed. Interior is plush and washable. The peak doesn't add a lot of turbulence. Unlike my last peaked helmet I can look to the side without issue, and adjusted all the way down is great for the shade & roost protection. It's good with glasses. Lots of room in that area and no pushing them around. Only gripe is that changing the shield means undoing the 4 nylon screws. Same routine if you want to use it without the peak. Top marks all round. Best helmet I've had in years. April 5, 2016
No more cheap helmets This is my first Arai and the most I've ever spent on lid. I'm ruined now and won't have anything less. The fit is excellent and the weight feels lighter than my previous "adventure" styled helmets. I'm in love with my XD-4. March 29, 2016
This helmet is a great value! The Arai XD-4 is a great value with great features not found in any of the many other helmets I have owned in the 40 years I have been riding. Of particular note is the lightness of weight, the exceptionally wide field of view, the improved venting features and the overall fit and superior finish. If I have any criticism, it is that the face shield tends to fog easily when you are motionless, and this can be cured by providing an antifog layer, such as that provided by Shoei. March 29, 2016
