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.

Features:

  • 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 5 265 265
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. January 19, 2016
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
