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

Arai XD-4 Explore Helmet 4.7 5 265 265
Buy this helmet it will last Great helmet worth every penny. I had mostly bought the cheap stuff to get buy and decided to get something I thought would last. I was over impressed by how comfortable it is for short rides and long rides. Sean Bluetooth set fits perfectly inside the helmet without the feeling there is speakers near your ears. Just wish it had a quick clip, other than that this helmet is the by far the best dual sport helmet on the market .. February 2, 2016
Great Helmet - just spend the money. we all know that $500-600 is a lot to spend..truth is, once you wear one of these for a while and then try on a different, less expensive helmet, like an AFX, the difference will be night and day. I use an arai xd3 now (which is pretty much exactly the same as the xd4) and feel not only safer but much more comfortable on my bike. My advice, don't screw around with cheaper helmets, even if you're a new rider. Go for the quality and you'll be happy riding for years. These helmets offer awesome padding, a wide eye port, nice air flow and, if you get the pinlock lens, theyre great in the cold. go for it. January 22, 2016
Great dual-sport helmet I borrowed a friends XD-3 helmet last year for an off road adventure trip. After wearing it for 6 days I knew I had to have one. I had a cheaper brand before but did not like the fit and the way the beak caught the wind and jerked my head when ever I turned my head. The Aria helmet did not do that plus it fit my head just right. For those reasons and the fact that Aria makes a top of the line helmet it why I bought the XD-4. Your head is very important why protect it with a cheap helmet. January 20, 2016
Great in the right conditions Arai quality and fit as expected. The color is perfect for being seen. It's not too noisy, the weight is right, the look is spot on, the features are comparable to competitors. Never though, have I worn a helmet that fogs so badly. Anything under 65 degrees and every breath obscures you vision unless you're moving beyond walking place. Below 50 degrees and no amount of airflow into the helmet, of which there is tons as it can be felt, clears the visor. So when the conditions are right, it is a great lid. When the weather is cold, I'm thankful to also have a Bell MX9 that simply doesn't fog regardless of the weather January 19, 2016
Great! Fit is great. Noise level not bad. Air flow is very good. Shield works great, can crack it just enough to keep the fog off but not enough to bother your vision. Balance is perfect and it's light weight. If I had to ding it on something it would be the peak and shield mount need a screwdriver or coin to change them, not a big deal. Overall a great helmet.

Best Helmet i ever have Best helmet i ever have, Arai is the best, Good shape, good weight November 24, 2015
Great vision and comfort As a hi-end product it fully meets my expectations. As a known strong and safe helmet in combination with great vision and comfort I think this is key points to a good helmet. This helmet gives the kind of comfort which makes it a thrill to wear it for the hole day. It also has good build quality and functionality, As for Scandinavian cold weather trips It also gives no issues really, fogging down the visor is at a minimum. This style of helmet gives some distance between your face and the inside of the visor, could give reflections if you use glasses. On the other hand using glasses in this helmet gives you no gnaw or pain, fits perfect with glasses. The helmet gives some noise in speeds above 110 km/h but less than expected from this style of helmet. If you want to spend the extra buck, this is the way to go! November 23, 2015
First helmet - Arai Perfection! This is my first helmet, the Arai XD-4 Solid Pearl Black, and I was admittedly worried about spending so much for a helmet without any prior experience. Having just purchased a 2015 WR250R I wanted something for the dual-sport nature of my new bike. I also wanted something from a rock solid, proven company backed by years of reliability and safety. With the reputation of Arai and the fact they had the dual-sport XD-4 helmet it was naturally the first helmet I looked into. Everything about the helmet "on paper" I liked. It has style, elegance and a nice sportiness to it I liked. My problem was none of the local shops carried a helmet in stock to try on and at over $500 bucks its a hard swallow. One place had an internal shell from an Arai and the guy said they were incredibly strong and well made. At 190Lbs, I stood up on the shell and jumped roughly 16-18 inches up and landed on the shell without it breaking or deforming. It remained rigid and firm as I landed on it. My head measures 22.5" or 57.5cm and looking at the Arai helmet sizing chart put me right at a medium. The week before taking my BRC course I had some unknown full face helmet in size large that was quire tight. Regardless I took the sizing chart on faith and ordered the Arai XD-4 in Medium. Note here also that I had read the XD-4 has a more general oval shape without removing any of the internal fit pads and i have an oval face/head. On receiving the XD-4 I can say the fit was perfect! It was initially quite snug! I really had to pull it down over my head however after a couple rides and a few hundred miles the pads have shaped to me perfectly and is now extremely comfortable. Really like the emergency cheek pullout pads! These help Emergency responders immensely when helmet removal is needed after an accident and should be in every helmet today. NOTE: I Wear Eye-Glasses and while you need to remove them each time you put the helmet on or take it off, they fit perfectly. Yes there is that word again however its almost like there are slotted groves in the padding because they slide on/off easily, never catch on anything and there is never any force pressing them against my head. I have 2 sets with straight arms and another with curved arms that wrap around my ears. Both fit with 100% comfort and zero issues. The front shield clicks closed firmly and remains so until opened. There seems to be centered open position where the shield can be adjusted about 1" however it puts the bottom edge at my eye level so useless to me. The shield opens fully and stays open securely and doesn't drop. Also the visibility range is amazingly wide, clear and true. I've yet to see any distortion I've heard of in some other shields. The top visor is easily adjusted with a coin or flat screwdriver and seems to be well built. It is designed to break free so be aware of that if you ride where it may be hooked or commonly bumped. I adjusted mine downwards fully and seems to be perfect for my use. Road noise is not bad and have zero complaints about it. Putting around on side/back roads its fine and when out on the highway pulling 70mph its a bit noisy bit closing the chin and brow vents 1/2 way and pulling the chin deflector down seemed to help. ALL the vents open and close securely with a positive feel. The brow vents have a 1/2 open and full open setting and I really like how it directs air over my forehead and not directly onto me. Top and back vents are easy to use and provide great venting. Being able to adjust the front chin vent to either come directly through to the face or redirect internally along the cheeks is very nice as well. I DO WISH there was a filter of some type inside the chin vent! With it directly open I hit a large swarm of gnats and well.. they don't taste that great! ;) Aside from that I cant say anything bad about the helmet. I am extremely happy with the purchase and can happily join the ranks of many many many Arai supporters! It certainly isn't cheap however the last thing you want an injury to is the head. Money well spent I believe! If you are on the line thinking about this helmet stop thinking and just order it! October 29, 2015
