Arai XD-4 Explore 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

Great Helmet at a great price this is the second one I have purchased, great all round helmet May 17, 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
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
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
Arai Quality Quality in keeping with Corsair V and dirt offerings. I use the Corsair V over the top Shoei, but prefer the Shoei VFX-W to the Arai dirt lid do to the close chin bar. This lid felt a bit tight on the forehead 1st ride, but felt better/somewhat broken in by ride end. No eye irritation in dusty conditions with visor down & high wrap Oakley shades. Worked well with said shades. I'm wearing a large in the Arais with a 23 3/8" head. A keeper for DS rides. Nice lids are expensive, but I find there's a good resale demand if they're not too trashed/old. March 29, 2016
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
