What's this?

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 5 296 296
Comfortable, Quality Protection When I got into dual-sport riding just a few months ago, I sought out advice from a good friend who had been a member of the GS Trophy team (representing the U.S. in 2010) about which helmet I should consider. His first words were to not skimp on a quality helmet, even paying a premium, because protection is nothing to spend short on. He recommended the Arai XD-4 and going by his recommendation, I bought this helmet. I'm glad I did. The helmet is extremely comfortable with padding that's easily removeable, as needed, for cleaning etc. I installed a Sena 20S bluetooth receiver and it integrates seamlessly with the helmet. The visor is easily removeable which is the one item I've taken off as it can buffet quite a bit when riding at highway speeds. The outer shell is tough and durable with vents throughout to maximize airflow while maintaining a sleek design. I would like to see a little more reflective paint on the sides and rear but other than this, I've been very pleased with the Arai XD-4 and have no problems recommending it to anyone looking for a quality helmet that's not too heavy and comfortable for dual-sport riding.

Slightly disapointed Got the helmet yesterday and one of the top vents isn't working. Hopefully when I get the next one it will be working properly. Plus 7 bucks for return -_- that sucks June 18, 2016
excellent helmet the helmet is very good and buying in the site is very quick and easy June 28, 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
Saved my life First off, I loved this helmet well before my accident. The field of view is fantastic, the fit is incredible. Comfort and build quality are everything you would expect from a premium helmet. But I have had a chance to test out some of its safety features first-hand, and now I love the helmet even more. About six weeks ago I was hit by a driver who turned left across traffic and into me. I contacted the car at the driver's side headlight and was thrown 80ft. I remember my head bouncing along the pavement until I came to a stop at the side of the road. Another driver (also a rider) stopped and popped the safety cheek pads out, and then helped me (very carefully) take the helmet off. All told I had compound fractures of the femur, tibia, and fibula in my left leg, and (as I would later learn) more broken bones in my ankle and foot. I spent 3 weeks in the hospital because of the injuries to my leg, but my head is perfectly fine, and that's thanks to Arai. Recovery is going to be a long process, and I don't know when I'll get back on a bike, but I know what helmet I'll be wearing when I do. June 22, 2016
Great helmet I was looking for a helmet that was light weight cool looking comfortable and different. I wear this on my commute daily of 40 miles each way on my dyna, I'm not tired or have a sore neck from wearing it. I sit up right when riding the peak doesn't catch the wind. It gets foggy when sitting still on days below 35 F with the vents open still stays warm when its cold but its also flows enough to keep your head cool when its hot out. June 18, 2016
Just a great helmet. This is my 3rd Arai helmet & they just keep getting better. I read some reviews on other helmets that had more features but I decided on an Arai because there a great wearing solid product you know it holds up. The liner & shape in the the new XD4 is a great fit & quiet couldn't be happier with the helmet. May 3, 2016
Great overall just a couple knit picks Overall I am very happy with this purchase. Like all good quality gear it is expensive but you get what you pay for. It is SNELL approved as well as the required DOT. I bought the high vis for its intended purpose and it doesn't fail me. Airflow is good but the vent on the chin directly in front of the lower parrt of the helmet needs some kind of screen as it will allow bugs and other debris to fly thorough and potentially go in your eyes. This has happened numerous times on my multiple long rides and is something I think should seriously be addressed. Other then the above flaw the weight of the helmet is great as well as the cooling. I don't sweat near as much compared to wearing my cheap BILT brand helmet (still decent and legal by DOT standards but not on the same level). Like I said before you get what you pay for. Also compared to my BILT brand helmet I have zero hotspots after hours of riding. That is until I put some u clear speakers in. Only after very extensive rides (4+ hours) do I feel SLIGHT discomfort and pressure on my ears. This I feel is normal considering the circumstances and the speakers installed. The clear screen offers great viewing angles and to me wider than normal. Also the sun shield offers great shading and doesn't really affect me on my enduro while going down the road. Plus it looks pretty awesome if I say so myself. The yellow matches perfect to the KLIM badlands high vis yellow which is good for people like me that like matching. Overall: buy it and feel safer knowing you bought quality gear. Customer service is amazing as always. June 9, 2016
