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 5 260 260
Arai quality, what else needs to be said? this is my 4th Arai, and coming off the back of an XD3, some of the new features appear to be quite nice. I like the larger buttons for the top intakes, and the addition of the brow vents to the line. Fit is the same as the XD3, and the metal flake in the black helps the lid look extra pretty :D It's pretty much everything I've come to expect from Arai, and if it fits your head shape and like the style, I absolutely recommend it. October 20, 2015
comfortable It's very comfortable and the ability to remove 5mm of padding made it even better as it was a little tight on the cheeks. Air flow is great, very stylish. Just a really nice helmet and worth the money. I wish the Arai logos were a little smaller though. October 12, 2015
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
Best helmet I've ever owned Love it, great helmet. Fit is excellent. Quiet, and well made. Spend the money it is worth it. October 5, 2015
Arai... Enough said ! Aria helmets have a "feel" to them ,that sets them apart from the other high end helmets. I bought this helmet and immediately removed the peak. I have no need for it as I only ride on the street. I love the extra wide vision from it. Vents great and can actually feel the air moving across your head. Had no fogging issues at all what so ever. Liner is very comfortable and my 23 inch head fit great in a large. I ride a R1200gs Lc and an 2006 street glide. Helmet "goes" great with both. September 14, 2015
perfect fit Tried the Shoei in MED but it was too tight in the cheeks. 23"head fit fine, but even after ordering the XL cheekpads, it was still too tight and I realized that it tickeled my regulation moustashe...no way I could stand that and after 50 years, not shaving it either! No problem with the Revzilla return. Ordered the Arai XD-4 Hi-Viz also in MED and......it fit PERFECT! Sure, it's snug, but not painfully so like the Shoei was. More room in front of the stash too. Bottom line is that the Arai MED runs a bit more spacious than the Shoei MED, at least for my head. JD September 12, 2015

RevZilla Store asked: Why did you choose this?
Kal W: Had an Arai Quantum prior to this helmet. Loved it but its way old now. Bike style has changed so helmet has changed with it. Thought it would go better with my Hyperstrada .No helmet I have tried fits better than an Arai. Oct 4, 2015
Theodore E: replacing gear from an accident, previous helmet was an XD3. and this one is pretty. Sep 25, 2015

Larry L: quality and function is why I choose Arai. Jul 5, 2014
Anthony G: I already own an XD3 which I love. Jun 9, 2014
jay b: i wish this had a sun visor like the shark but other than that i can't find another helmet better suited to adventure riding the the arai xd-4. loved the color scheme. wish troy lee would come up with a rad design for this model. May 5, 2014
Paul M: Arai helmets tend to fit me better than any other brand that I've tried,(long, narrow head shape). Undeniable quality and quality control. Apr 5, 2014
Gary L: Excellent reviews of a great Dual Sport Helmet, allows plenty of air flow and great field of view. Having worn it now for a couple months, great fit, quite, comfortable, and the colors match my 2013 BMW R1200 GSA 90th Anniversary Edition; cornet, but looks really cool. Chin strap is often very annoying to get buckled on and off and is the only negative. Mar 27, 2014
Bill W: Love the look and quality. Feb 18, 2014
Shean S: I ride up here among the frozen chosen North, and the flexibility combined with a pin lock system provides the ability to cover a hot day or a wet cold on the same trip. My current helmet fogs and its just not the same as my two Buddies I ride with. Tired of holding up the ride to wipe down. Feb 17, 2014
James U: I wanted a dual sport helmet, highly visible, matches my bike, can use in three configurations plus goggles if need be. Ultimately, Arai has a good reputation for quality and safety. Can not put a price on cranial protection! Oct 1, 2013
A shopper asked: I ride a 2013 Ducati Multistrada sport/touring bike with an upright seating position. I am planning to purchase a communications device at a later date and planning to use both on the highway. Is the XD-4 helmet quiet enough for a communications system or should I be looking at a Shoei GT Air, for example? I really like the style of the XD-4 but not sure how much more noise I will have to endure. Please let me know your thoughts. Thanks! Jun 1, 2014

A S: I also have a Multistrada and have had one outing with this helmet and a G9x. I don't have anything else to compare it too, but I was able to maintain communication with my riding buddy at speed up to 100mph/160kmh. It gets a bit noisy at higher speeds and the wind noise does make it a bit harder to hear clearly, but still very doable. My riding buddy has a GS adventure and it's much easier for him due to the better wind protection. Looking at a Puig aftermarket windscreen to try to improve this. At slower "legal" highway speeds it's just perfectly clear.

Mike R: I would say yes. I love these helmets, I had an XD 3 prior to the 4 and used it for 5 plus years. I also used an Autocom set up in both helmets. I have communications and music routed through my system. I ride a GS adventure and unless I'm driving at crazy speeds I hear the system fine. I think the 4 is a little quiter. I recently switched to a Sena Bluetooth and it works well too. Good luck in your choice, it works for me. Jun 4, 2014

Shean S: Hi Shopper,
Bought the helmet to use principally on my BMW 1200 GSA, but it was so comfortable I started using it on my other street bike too. I installed my bluetooth bike to bike G9 system without any problems. Noise is quieter than my sstraight up street helmet from Shoei.
Short answer, absolutely thi helmet rocks fo communications or just rockin' while you're rolling.

Spencer C: I don't have a comm system in my helmet but it is a little noisey 70mph+. I don't think it's that loud where it would be a problem but ask someone who wears the shoei. Jun 9, 2014

Roger L asked: Hey,

I'm about to head to the Himalaya's for 2 weeks, and considering getting this helmet as I'll be riding in all sorts of conditions, weather etc. My question is about goggles.

I'm considering getting the Liquid Image Torque 368 or 369 HD Goggles that will allow me to take video from my POV (without sticking my GoPro on the helmet). My question is:

"Can anyone confirm that the LI Torque Goggles fit this helmet?"

I'd hate to buy a $650 lid + $400 goggles and they don't fit...

Answer this · Send to friends Good question? Yes (0) No (0)
Anthony G: Unfortunately I have never tried the goggles under the helmet. All I can say is there is a lot more room inside this helmet than almost any other convention helmet. Jun 23, 2014
