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

Exceeded expectations I have owned two Scorpion Helmets, 1 previous Arai Profile and a Shoe Multi-tec. The fit was a bit tighter than the profile, but having more room in the chin area is a big plus. In less than 1,000 miles, this has become my favorite helmet. The Hi-Viz is precisely that. You can see my XXL melon for yards and I actually notice people staring at me like I am some sort of alien when I have this helmet on. I am a big fan of the visor and how it works to keep me from getting too much UV radiation to the face, and the way it directs airflow through the vents. I never thought I would go away from the Multi-tec but this is my new go to helmet. March 23, 2015
El mejor casco doble propósito . Sin lugar a dudas el mejor casco doble propósito del mercado. Excelente calidad de construcción , liviano, muy buen calce , cómodo y con la posibilidad de usarlo con o sin visera . El talle que uno debe comprar es el recomendado por Revzilla o por el fabricante Arai. Inmediatamente después del pago recibí la confirmación del envio y el seguimiento del mismo . Muy bien embalado el producto , llenos de bolsas de aires por todos lados , garantizó que llegue de manera impecable al destino. De confianza el casco y Revzilla. No duden en comprarlo .

2 Legit 2 Quit Awesome helmet from Arai. It has a very solid feel and overall quality construction. Peak is stable at high speed. Visibility is good. Had some cold weather fogging issues but most helmets do the same. I'm particularly happy with the looks and versatility of it minus the peak which will let me wear this on another bike (working toward a Street Triple R) which softens the blow of the price tag. Why are graphics so much more expensive? Face shield changes are easy enough. I expect to wear this thing for years. Completely worth the cost and just blows the other DS helmet I have away. February 25, 2015
Perfect!!! This helmet is close to perfect! Love it. Perfect fit and finish. I had a dilemma on the sizing, as my head size was between a Medium and Large. I wisely took the advice of my Revzilla customer service rep (via Chat) and sized down to a Medium. Good advice, and I'm very happy with this helmet. Also, Revzilla was able to track down my shipment -- given that UPS lost/misplaced it. Very happy camper. February 16, 2015
Great Helmet - Not the best in the cold I love this helmet, fits perfect and looks sweet. My only issue is the lens tends to fog on cold days. The airflow is great so the fog usually goes away once moving again. but every red light it fogs up worse then my bathroom mirror after a hot shower. I'm going to purchase a fog deflection mask and try that, if that doesn't work I might be switching to goggles for the cold season. Not the worst issue to have, but for a $500+ helmet I'd expect a better anti fog lens and breath deflection option. February 16, 2015
Hi-viz works, overall great helmet A buddy said the whole hi-viz thing was only a marketing ploy, that is until he admitted he saw me three blocks away because of this helmet. Just got back from a two day trip - another buddy said that I was easy to spot in gridlock traffic, all he had to do was follow the yellow blur. Helmet is light and quieter than my Shoei 1100. Only complaint is that one has to be careful that the helmet does not get marked up by incidental scrapes as the hi-viz paint can scuff easily. There is also enough black accents to make the helmet look cool. February 6, 2015
Good overall. Nice finish. Fit a little loose to my surprise. Ordered xxl w/ 24 1/2" head. December 23, 2014
Arai XD4 Purchased this helmet to use with my supermoto. I had the Icon variant before but felt like spending the money for something nicer. All I can say is that I love this helmet! Much better than the icon. Wind for seems better on this than the icon as well as noise level. I would definitely recommend spending the extra money for this one! January 26, 2015

Adam C asked: Can this helmet be used in conjunction with goggles? I really think that 85% of the time the shield will suffice...but on those really dusty dirt roads goggles could come in handy. Anyone have experience with this situation? Aug 17, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
John P: Yes, you can use it nicely with goggles. I have two different types of goggles, Thor and Scott. The Thor Ally ones don't fit very well. The Scott ones are perfect. Both have nose guards fitted onto them. That causes a little trouble fitting them into the helmet.

I'm kind of the same as you. I do only a little off road, but I do like using the goggles for slow rides as well. Nice on hot days.

Jon L: I have not used the helmet with goggles. I believe that you can remove the face screen and use goggles if you so choose. I dont know if you can use goggles with the screen in place. I am away from my helmet right now or I would try it out for you. Probably the Revzilla guys could do that. I do ride long distances in dirt and the face screen has always worked very well at keeping the dust out Aug 19, 2013
Reply to Jon Good answer? Yes (0) No (0)
Albert G: I gave it a try and they did fit. Not much of a gap around the goggles. If its just dust control you want then it would be better than the shield but I think you will sacrifice ventilation and make it a lot hotter to wear. My Klim F4 seems to have much more room in this area, as in it was designed for goggles where the XD was not. Aug 19, 2013
Reply to Albert Good answer? Yes (0) No (0)
TODD B: Goggles will easily fit under the closed visor. I usually ride with goggles on and the clear visor up on dirt/gravel roads to get some air. If there is too much wind noise on paved roads, I flip the normal visor down over the goggles. I use Oakley goggles if you're looking for a goggle size reference. Aug 20, 2013

Stuart H: Haven't used goggles per se, but a slightly cracked visor and sunglasses has done me well on most dusty stuff. On 990 Adv, I'm not THAT close to mi amigos- not like 450's. 990 SE maybe!! Great helmet thus far. Aug 19, 2013
Reply to Stuart Good answer? Yes (0) No (0)
Jesse E: I alternate between goggles and shield. Primarily because I like the wind in my face, but like my eyeballs protected. So goggles work perfect. Shield can be removed in about 3 minutes or less. Aug 20, 2013

A shopper asked: Hi, I intend to get this awesome Arai XD4 Explore. My head measures 58.5cm as per your video guide. My face shape is a bit squarish. Should I go for the Medium or Large size? Will place an order once advised. Thanks in advance! Jan 5, 2014

Rob S: First let me say that if you purchase this helmet you will not be disappointed. 45 years of riding and this is the best built, most comfortable and most versatile helmet that I have owned. The shape of your face I believe should be fine. The sizing is a little more difficult to answer because your right there between med. and large. I have the previous model (XD3) that I was between sizes and bought large because the salesman (NOT Revzilla) told me these helmet will soften up and break-in and would be loose. That did not happen and resulted in discomfort and headaches. The pad layers can be removed as needed to achieve the perfect fit. With the XD4 I was between large an XL, went with the XL and took 1 layer out of the cheek pads and had a perfect fit. I would start with the large (you want snug not loose) Revzilla is great on their return policy if it not used or worn. I hope this helps. Rob S. Jan 7, 2014

Ken P: Hello! I have this Arai XD4 and wanted to let you know that the fit is great! I measure to exactly 58 cm and I wear a MEDIUM. I would definitely recommend getting the MEDIUM. It should be a perfect fit for you, as you want it to be slightly snug. That being said, I have been told that you would order a MEDIUM in any helmet regardless of the MFR.

Good Luck and enjoy the XD4!

Peter B: What I did was bought both sizes and returned the medium . The large fits me perfect. With the return policy of revzilla it makes perfect sense to do this method. Try on each helmet and wear for a least an hour or two. Remember the helmet will get bigger after break in. Try on sunglasses also very important. You'll know what size to choose !

Stuart H: I am right about at 59cm and fit the "intermediate oval" shape pretty perfectly. I have a medium XD-4 and it fits like a glove. If you don't like a snug fit, maybe order up the thin cheek pads with it. Love the helmet. Light years better than my old XD. I didn't check out the video guide, though I have high cheek bones and "germanic" features. Jan 6, 2014

Steve Y asked: I am thinking of getting the shoei hornet or the aria xd, I have only had less exspensive helmets in the past in which I take a size xl, the stores close to me only carry these other brands which some of the xl seem so tight I think they would give me a head ache. I measured my head per your video and it is 231/4" or 59 cm. I have a round shape head. I see these measurement fall into the large ,but not sure wheather to stick with the xl. the helmet I wear now is a Fulmer xl 3/4 helmet & seems to fit well. But I tried a full face Spy helmet locally & had to get an xxl ? Between the Arai & the Shoei, does one fit a more rounder head shape better than the other?

George B: I measure 59,5 cm. I bought the large (L) one. When I first tried it on, I said what the heck did i just do. It was almost impossible to put on, and the pain and squeeze was unberable..
1. I pressed the EPS (the protection foam past the padings in the area where it hurt me - a little above the temples and towards the forehead - carefully with a rounded object. I'm talking about something in the region of less than 1mm, noothing tat would compromise the helmet's integrity.
2. I took out the humongous cheek pads, and depressed the EPS section of thoose a lot... Note: I'm a little big with a lot of cheeks!
3. I wore the helmet...

The hellmet is now fitted to my head like a glove. It's just perfect, as snug as it needs to be, and comfortable for a lot of miles. (As i write this, I'm in Germany at almost 2/3 of my european tour of 11.000 km)

So my suggestion would be to buy the L instead of the XL. As far as the cheekpads and the liner, you can always buy thinner ones than the ones it's sold with (there are many options), instead of customizing them as I did!

As far as the Shoei vs Arai is concerned, I can't tell. I previously had a very expensive road Shoei, and it fitted me perfectly.

Hope i helped,

Robert C: I have a Shoei X11 (size L) which I've used for years and love. I had to resize the pads to optimize the fit. I also have the Arai XD-4 which is also an excellent helmet. The Shoei is rounder shape, but I find that if you remove the layers of pad on the side of the Arai (per their instructions) it is also comfortable for all-day riding.

If rounder head shape is the key factor, I'd try on the Shoei Hornet to test the fit, but I think you'd find you can remove the thin layers of the Arai padding to make the fit work fine.

Hope that helps.

LAURA AIKEN B: If you measured the size of your head and matched it to the Arai sizing chart, you should be good to go. I personally prefer a snug fit knowing that the helmet will loosen up over use/time. The XD-4 also has the layers in the cheekpads you can tear-out for a better fit.

I really like mine, it's perfect for what I was looking for. If for some reason you ordered the wrong size - send it back. Just open the box very carefully and try the helmet on BEFORE you remove any labels. If it's sooo totally wrong it should be evident immediately. Good luck!

Answer this · Send to friends Good question? Yes (0) No (0)
RevZilla: This helmet is not designed for use with a specific system, but you can use a universal kit such as a Sena SMH-10 or Scala Rider G9. There should be enough room in the ear pockets to fit the speakers for both systems. Mar 26, 2013

Dylan J: The SMH-10 went into my helmet easily and I don't notice that the speakers are tucked into the ear cavity Aug 19, 2013
Reply to Dylan Good answer? Yes (1) No (0)
Paul M: I swapped from the Shoie Hornet to the XD4 because my coms speakers hurt on extended rides. Much more room in the XD4 for speakers.
My first xd4 (crashed in 1st one) was noisier than the hornet. Not sure why but my newest purchased last week is much quieter. Is the latest & is different color on bottom lining. Feels snugger not just new helmet snug maybe they improved the snugness fit not sure. But is quiter similar to the Shoie this one maybe a little noisier but not much.

Randall M asked: Looking at the Arai XD-4 Explore helmet in orange. Can anyone tell me if the color is Deer Hunter, High-Vis orange or if the color is more of a KTM color match? Can't quite tell from the pictures. Thanks! Mar 26, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Stuart H: Definitely not your standard hi-viz. It's quite close to KTM- close enough but with more depth to it. Perhaps a tad darker but not by much. KTM orange is kind of flat. This has a metallic flake that gives it depth and is subtle, so the black has a little pop as well. I absolutely love mine. Get lots of nice comments on it. The price tag hurt a bit, but haven't looked back. And I'm guessing it's pretty easy to see on top of that.

Good luck!!
