    XD4 means "Crossover Design" because it crosses over into so many riding styles. You can quickly and easily change it for adventure touring, dual-sport, Supermoto competition, commuting, whatever. Visually, it looks like a dirt helmet, with its peak, protruding chin bar and the opening for goggles. But the XD4 Series also has a full face shield like a street helmet, a face shield that easily slides up under the peak. And you can remove the shield and/or the peak in no time, and then easily re-install either or both whenever you like. Arai is taking you to the next level with the XD4.
  • High-flow peak channels air directly into the front vents.
  • Twin-cam Shield Pivot System allows the face shield to operate fully under a peak that can be lowered for better aerodynamics.
  • Fully removable/replaceable and washable liner.
  • 4 top vents. Dual Intake/Dual Exhaust Ventilation - dual 1/C top intake vent and Double Delta bridged exhaust vents designed to draw significant volumes of air from helmet interior.
  • CLC (Complex Laminate Construction) shell - fiberglass composite is stronger and lighter - allows use of softer, less-dense liner materials inside for increased rider comfort.
  • Efficient chinbar vent (with interior and exterior controls) flows fresh air to the mouth area or across the shield interior to help prevent fogging.
  • Large chinbar side exhaust vents draw out additional hot air.
  • Meets or exceeds Snell and D.O.T. standards.
  • For proper fit and size measure the circumference of your head 1" above your eyebrows and around the largest portion of the back of your head.
    20 7/8" – 21 1/4" -------- X-Small
    21 5/8" - 22" ------------ Small
    22 1/2" - 22 7/8" -------- Medium
    23 1/4" - 23 5/8" -------- Large
    24" - 24 3/8" ------------ X-Large
    24 3/4" - 25 1/8" -------- XX-Large

Why wear anything else?

Comments On Nov 09, 2015:Quite possibly the best helmet ever for adventure riding. It's so comfortable you forget it's on. Lots of side view makes it a safe helmet when you're in traffic and have to maintain your forward vision. Plus Arai's safety features and reputation make it a no brainer. I used RMMC's sizing chart and was awarded a perfect fit. Helmet was in stock and I had it to my door in two days. 5 stars to RMMC and Arai.

Like wearing a pillow

Comments On Jul 14, 2015:Really like this helmet. I had the XD3 and when it came time to replace had to get another Arai. The fit is so comfortable and it is light. I used the size chart and it was right on. The XD4 has better ventilation in my opinion. I feel very safe in the helmet. Yes, the price was a struggle to get by but it's your head. The only thing I could complain about is the plastic air ducts on the top. I have not done it but could see breaking these going under and hitting a tree branch. All in all money well spent.

great fit, comfortable

Comments On May 02, 2014:This is the perfect helmet for me, a little pricey but my head is worth the extra couple hundred dollars! The visor is nice to have but I mostly tuck it up and use goggles.

Great fit

Comments On Mar 25, 2013:this helmet is very well made! the cushioning has a superior feel to it compared to other helmets I've had. the face shield is CLEAR!! my other helmets all had some distortion to the shield, not this one, love it! also wearing sunglasses is no problem the cushioning actually accepts the frames very well. goggles fit no prob.. a bit pricey, but hey, it's your head...
