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.

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

Great Helmet
First, I ride a 2013 BMW F800 GS (I also have a Ducati Streetfighter and an Arai RX-Q, see my comments below) with a Touratech touring windscreen which is approx. 4” taller than the OEM screen. I am 6’0” tall but wear 30” inseam pants which makes me slightly more “top high” from the waist up. This helmet is for on-road-off-road use on the BMW.

My major concern before purchasing was wind noise but my experience has been that the bike, windscreen, and my body height is more of a factor than the helmet. My normal riding position on the BMW puts me just inside the turbulence zone of the air going over the windscreen. If I stand up slightly (+3”) on the pegs it puts my head into the relatively smooth air coming over the screen. If I do a super-bike tuck or lean forward lowering my position I get completely behind the screen with 95% of the air blocked. My other helmet, for riding on the Ducati Streetfigther, is an Arai RX-Q. The Streetfighter has ZERO wind protection and the RX-Q is quite tolerable for noise up to freeway speeds and no ear protection. The RX-Q on the BMW is noisy from about 30 mph up. The XD-4 is almost exactly the same, with the turbulence causing a general rumbling noise in both helmets. With either helmet if I stand up on the BMW into the direct air the noise level drops. If I lean forward behind the screen they both are very quiet. So for ME, on the BMW, with this particular setup, the XD-4 behaves noise-wise very closely to the RX-Q (which I find very tolerable). BTW, this particular windscreen setup while not perfect is a good compromise, it blocks the blast of air on your chest and doesn’t intrude on forward visibility.

Some other comments after about 2k miles and a couple of long trips ...
On a March three desert tour in Calif. with temps in the 90’s I found the ventilation to be excellent, noticeably better than my RX-Q. However, on very cold mornings going over mountain passes the more open neck area of the XD-4 lets in more air than the RX-Q. I end up putting on my Klim neck gaiter sooner than with my RX-Q.
I wear prescription glasses and purchased Scott OTG goggles primarily for low speed, hot weather, off road travel. The goggles just barely fit inside the face opening of the XD-4 and require a bit of fiddling to get over the glasses but inside the face opening. Other brands/types of OTG goggles may or may not fit. Obviously the airflow with the shield up and goggles on is even better.
The XD-4 has very good peripheral vision, but obviously not with goggles on.
On the desert trip and over a series of days of high winds the helmet developed, depending on wind direction/angle to the helmet, a very loud low frequency humming/buzzing noise. It got to be really annoying. I discovered that the screws holding the visor on the helmet had become slightly loose, snugging them up tight made the problem go away.

Summary. A great helmet for what it is designed to do with amazingly few downsides when compared to its all-pavement cousin the RX-Q. A bit pricey but worth it. I would buy another. Attached "selfie" photo gives an idea of the close fit with OTG goggles on.

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.

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.

One year of ownership, still looks like new.
Living in San Diego, I commute solely on a motorcycle and love the Arai XD4 helmet. After 52 weeks of close to daily use, the helmet is still extremely comfortable and shiny with minimal upkeep. It is very easy to remove the internal liners to clean. The fit and finish are superb and the airflow is excellent without being noisy. The helmet is very stable at higher speeds. A bluetooth setup easily fits as well with the speakers snugly fitting in the cheekpads. The only issue is if you turn your head too far to the side at speed there is a whistling sound.

Nice Helmet
Started out with a cheaper dual sport helmet and after loosing the screw that held on the visor on a long ride decided it was time to get serious about my riding. So far, I would say it is a very well built helmet and very comfortable. If I have a complaint, it is that when the visor is up it is still very noticeable at the top of my line of sight almost distracting (might just need some time to adjust to the new style). The venting is good and I'm looking forward to some summer riding to really see how well it all works. Overall I would recommend this helmet and I am glad I got it. As always shipping was quick and painless and the video review sealed the deal for me.

Great helmet.
Solid helmet. A bit noisy and has drag going over 60,but it breathes and is comfortable (even with Houston's humidity). I would recommend it. Fit is snug, as it should be. Make sure to know your size.

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.

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.

I am not a brand freak but ARAI keeps it position on top because they earn it.
Everything on the helmet was thoght. Its light weight, plus the air inflow, plus the quality of the materil makes it my best helmet so far.
I owned a S900 shark with sun protection. It doesn t come closer to this one.

One problem only: it is a little tuff to attach the band below your neck.

Besides this, i trully recommend

Wanted a quality helmet and the Arai was highly recommended. I am riding a Yamaha Super Ten and the XD-4 fits my needs. Although I wanted white and black, I am originally from Pittsburgh so the black and gold is appropriate. Can't wait to start riding.

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.

Arai helmets tend to fit me better than any other brand that I've tried,(long, narrow head shape). Undeniable quality and quality control.
Paul M on Apr 5, 2014
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.
Gary L on Mar 27, 2014

Bill W on Feb 18, 2014
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.
Shean S on Feb 17, 2014
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!

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!
A shopper on Jun 1, 2014
BEST ANSWER: 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.

Is the visor removable? is there holes nice removed ?i know there was a ducati diavel xd4 without the visor
A shopper on Mar 1, 2015
BEST ANSWER: It sounds like you're referring to the peak... Yes, it is removable. The face shield is the piece that tucks up under the peak. The aerodynamics of the peak are such that you should not need to remove it, unless for aesthetics. I'm assuming you would not want the peak for street riding. The beauty of the XD4 is its versatility... you can use it as a street, dirt or adventure helmet. Hope that helps. :-)

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...

Cheers
Rog42
Roger L on Jun 21, 2014
BEST ANSWER: 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.
The vents on the front top of the helmet, do they come off as well? one of mine quite clicking after about a week and i would see if there was something in it if it would come off.
