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 5 254 254
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 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 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
Comfy, but a bit noisy. I bought this helmet for my wife. She loves the comfort, view, venting, and shade from the visor. The wind noise inside is louder than my new shoei Hornet. Also her visor whistles above 50 miles per hour. August 14, 2015
High quality helmet with great vision, venting and other features I've used both Shoei & Arai helmets for over 20 years now in mostly street/track riding. Now that I've added off-road/ADV touring to my riding I bought the Arai XD-4. I tried on the Shoei Hornet DS and X2 helmets but felt the Arai was better for me overall. I'm very satisfied with my purchase of the helmet and additional dark face shield. It allows long, comfortable rides in various conditions and the only time I even think about the helmet during rides is to open/close the effective vents. The peak is effective for shielding your vision from direct sun in your eyes when riding and isn't bulky or obstructive otherwise. The shield is easy to swap if/when you need to using just a key or a coin to remove and replace the screws. The helmet allows enough room to wear sunglasses with the helmet on and causes me no discomfort at all. I'd highly recommend this helmet. July 27, 2015
I definitely recommend this product. I have had Arai full faced helmets in the past, and this one feels and presents just as well, if not better. The larger lens allows for better visibility. I installed the intercom from the previous Arai (Quantum J) and it fits much better. Definitely a great looking, safe product that got a lot of attention from the other riders. July 27, 2015
My favourite helmet I have upgraded to XD-4 from my XD-3 that was slightly too tight (L), went XL with XD-4 it feels a little loose I guess I'm unlucky to be right on the size edge, replaceable cheekpieces will fix that I hope. Other than that just like XD-3 I love it, fit, feel, handless hwy speeds nicely but most importantly vents really good. July 23, 2015
Worked as expected It bought this product to use with my 2015 GSA. It fit me a little tight around the temples but I removed the 5mm extra foam referred to in the product doc and it resolved the issue. This feature was the main reason I decided on this helmet. I am a little disappointed on the noise level. I have a Schubert C3 and it is quiet on the GSA compared to this Arai XD-4. At highway speeds I use ear plugs and it does resolve the noise issues, However the XD-4 is better ventilated and has better overall view of the road. The shield stays put wherever it is put at any legal speed. I wear glasses and it is a pain getting my thin flexible clear prescription glasses on, however my prescription sunglasses go on easily. The fit and finish and graphics are first class as you would expect in such a pricey helmet. The sales literature here seems to indicate that this helmet is Snell 2010 however the Snell inside the helmet label says M2015. July 8, 2015
Love this helmet I love this helmet. Fits very similar to my old Arai Profile...maybe just a tad bit more narrow. But fine. Much cooler when off road, more space around face...which is what it was designed for. Can't go wrong with Arai..costs more because it is BETTER! July 6, 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
Myles M: Unsurpassed Safety Level Oct 4, 2014
Tony V: Reviews from adventure forums. Oct 2, 2014
U S: replacing my 6 year old XD2 Aug 25, 2014
Mark T: Already have an XD-4 explore. Great helmet. Aug 24, 2014
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

Anthony G: The visor tucks up so neatly under the bill that I would not remove it because you loose all the protection in case of bugs, and rain. Mar 2, 2015

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...

Jun 21, 2014

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
