What's this?

Arai XD-4 Helmet

The Arai XD4 is world renowned for being one of the best ADV touring helmets on the market and one of the few that achieves a Snell 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 Arai XD4 Helmet has also been aerodynamically tuned and, in concert with the removable floating peak, 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
  • FCS (Facial Contour Support) cheek pad design with a 5mm peel away layer
  • 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 M2015 approved

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.

First helmet - Arai Perfection!
This is my first helmet, the Arai XD-4 Solid Pearl Black, and I was admittedly worried about spending so much for a helmet without any prior experience. Having just purchased a 2015 WR250R I wanted something for the dual-sport nature of my new bike. I also wanted something from a rock solid, proven company backed by years of reliability and safety. With the reputation of Arai and the fact they had the dual-sport XD-4 helmet it was naturally the first helmet I looked into. Everything about the helmet "on paper" I liked. It has style, elegance and a nice sportiness to it I liked. My problem was none of the local shops carried a helmet in stock to try on and at over $500 bucks its a hard swallow. One place had an internal shell from an Arai and the guy said they were incredibly strong and well made. At 190Lbs, I stood up on the shell and jumped roughly 16-18 inches up and landed on the shell without it breaking or deforming. It remained rigid and firm as I landed on it.

My head measures 22.5" or 57.5cm and looking at the Arai helmet sizing chart put me right at a medium. The week before taking my BRC course I had some unknown full face helmet in size large that was quire tight. Regardless I took the sizing chart on faith and ordered the Arai XD-4 in Medium. Note here also that I had read the XD-4 has a more general oval shape without removing any of the internal fit pads and i have an oval face/head.

On receiving the XD-4 I can say the fit was perfect! It was initially quite snug! I really had to pull it down over my head however after a couple rides and a few hundred miles the pads have shaped to me perfectly and is now extremely comfortable. Really like the emergency cheek pullout pads! These help Emergency responders immensely when helmet removal is needed after an accident and should be in every helmet today.

NOTE: I Wear Eye-Glasses and while you need to remove them each time you put the helmet on or take it off, they fit perfectly. Yes there is that word again however its almost like there are slotted groves in the padding because they slide on/off easily, never catch on anything and there is never any force pressing them against my head. I have 2 sets with straight arms and another with curved arms that wrap around my ears. Both fit with 100% comfort and zero issues.

The front shield clicks closed firmly and remains so until opened. There seems to be centered open position where the shield can be adjusted about 1" however it puts the bottom edge at my eye level so useless to me. The shield opens fully and stays open securely and doesn't drop. Also the visibility range is amazingly wide, clear and true. I've yet to see any distortion I've heard of in some other shields.

The top visor is easily adjusted with a coin or flat screwdriver and seems to be well built. It is designed to break free so be aware of that if you ride where it may be hooked or commonly bumped. I adjusted mine downwards fully and seems to be perfect for my use.

Road noise is not bad and have zero complaints about it. Putting around on side/back roads its fine and when out on the highway pulling 70mph its a bit noisy bit closing the chin and brow vents 1/2 way and pulling the chin deflector down seemed to help.

ALL the vents open and close securely with a positive feel. The brow vents have a 1/2 open and full open setting and I really like how it directs air over my forehead and not directly onto me. Top and back vents are easy to use and provide great venting. Being able to adjust the front chin vent to either come directly through to the face or redirect internally along the cheeks is very nice as well.

I DO WISH there was a filter of some type inside the chin vent! With it directly open I hit a large swarm of gnats and well.. they don't taste that great! ;)

Aside from that I cant say anything bad about the helmet. I am extremely happy with the purchase and can happily join the ranks of many many many Arai supporters! It certainly isn't cheap however the last thing you want an injury to is the head. Money well spent I believe! If you are on the line thinking about this helmet stop thinking and just order it!

Love it! Great visability & the visor pays off on every ride.
The XD-4 is my second helmet. I began riding just over a year ago and had been using a friends Bell racing helmet until I purchased the Arai. I've gone about 14,000 miles in the XD-4 and it's great!

Viability is great, airflow is good and has multiple settings, the liner is comfortable and can be removed for washing, and the visor will be your best friend when you're riding into the sun or in the rain. On that note, I have been caught in the rain a few times and I've never had any issues with water getting into the helmet.

Now lets talk about the visor: Some reviewers claim that they can't feel the visor at all. Of course you can. The real question is; is it a problem? and the answer is no. At 40 mph or less you won't really feel anything. I've taking tons of highway rides at 70+ mph and you can hardly feel it. The only time you'll feel it is when you look to the side to check for traffic, and some of the pressure you feel may actually be associated with the longer, lower extending chin which is a common design feature on most dual-sport helmets. I don't feel the pressure on the top of my head, I feel it on my chin. But again, it's so slight that I don't think it's an issue. I've never suffered any discomfort after wearing the helmet for up to 10 hours at a time.

VISOR pluses: Regardless of how well you plan, you'll be riding into the sun at some point. The visor works just like a baseball cap. The visor also helps to deflect road dirt and the many small things that fall from overhanging trees or structures. Perhaps my favorite; when you see that swarm of gnats in front of you, just dip your head and your face shield stays clean, works the same with flying mud when you're off-road. In addition, when the shield is up, the visor gives it some protection. The visor also helps to keep rain off the face shield at slower speeds. I love it!

At this point, I can't see getting a helmet without a visor, but, the nice thing about the XD-4 is that the visor comes off easily and can be stored in your bag.

Ride Safely!

The Best Helmet I've ever owned
I've worn Arai since the mid nineties. They've always had excellent quality, features and performance.

I recently tried a different helmet brand, but after just a few months came back to Arai. All my past Arais have been road race versions, so noise is relative, but the XD4 is about average. Either way, I always wear ear plugs as NO helmet is quiet enough to keep from damaging your hearing.

I wanted a helmet that would compliment my 2014 R1200 GSA. It had to be light, have good venting, accept goggles for off-road adventures, have provisions for headphones for communications, and have that aggresive ADV look. The XD4 checks all those boxes.

The peak/visor is an awesome attribute. Aimed right, it doesn't catch stream air unless I purposefully look up, then, yeah, it's an air brake, but what did you expect? The windscreen on my GSA negates most of this issue anyway. It's great to have the visor when riding into the sun. While my buddies are being blinded, holding up their arms to block the sun, I don't have to do a thing - the visor is doing its job.

The helmet accepts my Scala Rider G9x easily, the recesses in the cheek pad have ample room to fit the speakers behind the soft covering.

The paint is excellent. I got the matte black and am stoked. With the dark visor it looks badass - Lord Vader would approve.

The vents are very good. I can't comment too much on the mouth vent, since the windscreen on the GSA blocks that, but the top vents and brow vents all work very well. I recently moved from SoCal to NYC, and in the SoCal summer, the vents kept my head from exploding, and here on the east coast, they kept my head cool during the humid summer days. Now, in the fall/winter (down to 25F) with the vents shut, I feel NO cold seeping in. My head stays warm.

The one issue the XD4 suffers from, is fogging. It doesn't benefit from Arai's usual de mist lock (WHY???) so once the tems drop much below 60, it fogs. You can ride with the visor cracked, and that keeps it from fogging, but that gets really cold when you're in the 30's. The good thing is, the available pinlock lens/visor cures the problem. The question is why didn't Arai include this in the box, considering the purchase price? Regardless, it's still worth the extra investment. I bought the yellow lens for high contrast/cloudy days, and it's awesome. Now, my XD4 is complete. I love it.

Vibration
Since this is one of those "dual sport" type of helmets with a visor, those riding are at some point going to get on a highway and get up to highway speeds.

With that said...when riding down the freeway at 55-60 there is understandable wind noise. So to protect my hearing during sustained freeway riding, I run custom ear plugs. That cuts down the wind noise to almost nothing.

What was interesting is that without the wind noise I started noticing a low frequency hum...somewhat a throbbing hum. Could not figure out where that was coming from. I would bend over behind the windscreen and it would go away, get back in the airstream and it would return.

Eventually I realized that it was the visor that was vibrating and causing that throbbing hum. Reach up and grab the visor, the noise goes away. Then I started looking and you could actually see the visor vibrating. I then started reaching up and squeezing both sides of the visor with my hand and the vibration went away.

So, long story short...I started putting a fat rubber band around the visor to give it a bit of an "arc" and the problem goes away. Weird having a rubber band up there, but it works. Thought about getting a piece of aluminum, bending it in a slight arc and pop riveting that to the visor. Still might go that way.

I contacted Arai on their website...never heard a thing. All it would take to fix the problem would be to make the visor a little more beefy in that area and the vibration would stop.

Once lost, hearing usually does not return so it's important to protect that hearing at all costs. Constant wind noise will damage your hearing. At the very least wear disposable foam if traveling over an hour.

Hey Arai...fix this please.

Good overall but falls short for the price..
The reason I bought the helmet is because I was sold on the safety features and believe that it adds protection in an off. That is, after all, why you wear a helmet and is a good reason to not go cheap on this piece of gear. Also, I ride dual sport and do in fact go off road a fair amount so I liked the ease of use and flexibility of being able to take the peak on or off for goggles -- a nice to have but not really a determining factor for me.

I have worn the helmet for a few months every day and at all times of day and in different conditions (e.g., windy, not windy, cold, warm, hot, street and dirt, early in the day, late at night, east coast AND west coast).

For the most part it does what it says it does, its comfortable for an all day ride (12+ hrs), its light, GREAT peripheral vision, decent airflow.. but my one gripe, which is really two gripes is the FOGGING. Anyone who says this helmet doesn't fog hasn't ridden with it in fogging conditions or is a salesman. It absolutely, without a doubt, fogs and fogs to the point that I have to lift the visor to be able to see. If you are paying up for this because you think it wont fog, think again and look elsewhere. I did buy the pinlock which I understand will solve the issue. But for a helmet of this price at the top of the "food chain" pinlock and other effective anti-fogging features should be STANDARD.

Being able to see is a critical safety function that I expect my top of the food chain helmet to have completely figured out and have all necessary parts included on day one. its bad form to not include the pinlock system or whatever additional steps are needed to avoid fogging, knowing the rider will quickly figure out something else is needed and be ready to sell that add on.. all the while marketing the brand as the best. c'mon! This helmet is a safety device.. seeing in fog is a big part of the safety equation! If Arai is supposed to be the best or among the best, provide what I need to keep me safe. Or at least give me a heads up that I'm going to need to purchase something that's not included!

Spend the extra dough!!
So I initially bought the AGV DS EVO helmet with the touring graphics. I rode 60 miles with it and nearly went deaf and was pretty disappointed with the overall construction,and its made in china. I promptly returned it for the XD 4, and spending an extra 100 bucks was sooooo worth it! These helmets are not close to comparable, though they share a page when displayed. The XD's fit and finish are impecable, venting is great , visor is easy to operate and it's quiet. This helmet is worth the money, I've found my helmet life partner.

Should have bought it sooner
I struggled with the price but now that I pulled the trigger I regret not buying it sooner. Great helmet. I'm giving features and air flow a 'good' rating because the shield doesn't work well with a pinlock and fogging is an issue and the shield doesn't work with a photochromatic insert either and these are both great add ons for my street bike helmets. Hopefully either Arai or the after market suppliers will remedy this

No more cheap helmets
This is my first Arai and the most I've ever spent on lid. I'm ruined now and won't have anything less. The fit is excellent and the weight feels lighter than my previous "adventure" styled helmets. I'm in love with my XD-4.

Style, performance, and safety... this helmet packs all three into a reasonably priced package. Great on road, even better for mixed adventure situations. Only downside is a bit of excessive noise at freeway speeds.

It's top of the line in its class, lowest cost of the platform (solid vs graphic) and offers the best protection of any of the helmets within the category. Seemed like a clear choice.

Four Arai helmets and I've never been disappointed. This one is no exception.
MontereyBS on Jan 1, 2016
I chose this help because of the product name & I like the style and look.
Javier C on Dec 1, 2015
Great helmet. I use goggles with it also sometime, or just good sunglasses on easy rides.

I tried on a bunch of helmets in the Philly store and narrowed it down to two helmets, the Arai XD-4 and the Shoei Hornet X2. I really liked this one, great fit and features. Cheek pads are higher in the XD-4 when compared to the Hornet X2. The X2 pushed my cheeks up and made it less comfortable.

Very comfortable, well made helmet, relatively quiet - I'm answering calls on my Sena at highway speed and the caller couldn't tell I was on a motorcycle. Puig windshield helps too. Of my four helmets this is my favorite.

I have had Arai XD helmets for over 10 years and love them for adventure riding

This is an excellent helmet. I chose this one because I like the visor, and it fits my head. Very comfortable.
Cyndy K on Jul 31, 2015
I trust Arai and wanted a dual sport helmet.
Danh B on Jul 14, 2015
The best, most comfortable helmet I have ever worn.
Trish H on Jul 2, 2015
Because a helmet must feel great when it is on your head all day long. Otherwise your just annoyed.
John R on Jun 5, 2015
Revzilla top pick for Adventure bike helmet. Anthony's video was great. Arai product line is top notch as well
James M on May 26, 2015
Appears to be the best quality dual sport helmet out there, and is highly recommended by the RevZilla experts.
Phillip W on May 25, 2015
It's the gold standard in ADV helmets!
Robert R on May 24, 2015
have the XD3 that saved my life. I wanted to get the newer XD4 model
Alexandre T on Apr 27, 2015
It's a versatile helmet which can be used on and off road, and the SNELL rating was important to me.
Mike A on Apr 8, 2015
Other riding friends use this helmet and swear by it.

style mainly..

My previous helmet (Arai XD3) saved me from serious head injury in a crash which destroyed the helmet. I have no hesitation in replacing it with an XD4 as I know first hand how dependable they are when it counts!
M A on Dec 2, 2014
I choose this helmet because I had to learn the hard way that my Shubeth C3 Pro is not meant for the dirt. This helmet is touted as the top of the food chain in it's category. I think the side vision could be better and although I don't have any major complaints with it, I think it's just a good helmet, not a great helmet.

Friends recommendations!

I owned an XD previously and this version is even better.
Mark V on Nov 9, 2014
Excellent reviews
Rob S on Oct 24, 2014
Arai is the best and my head shape puts me in Arai, too damned expensive!
Gary S on Oct 22, 2014
Great reviews, price, quality, past positive experience with brand.
Scott S on Oct 12, 2014
Style, performance, and safety... this helmet packs all three into a reasonably priced package. Great on road, even better for mixed adventure situations. Only downside is a bit of excessive noise at freeway speeds.
Troy B on Sep 9, 2016
So worth the money!

Can you install a SENA 20S using the clamp bracket or do you need to use velcro?
A C on Jun 12, 2016
BEST ANSWER: The clamp works fine. I've had 2 XD4's with the Sena 20S and no probe installing with the clamp on either one.
My head is exactly 23 inches, which accrding to the size chart, is right between the M and L. Which size should I buy?
A shopper on Aug 24, 2014
BEST ANSWER: I was in the same position and purchased a medium, I had to return it for a large. It fit my head but so tightly that it gave me a headache after 5 minutes of wearing it in my living room. The large fits great for me.
I am looking at getting the XD4 but I have one major concern the ability to clean bug guts from the vents. On most of the videos it shows the rear vent removal but nothing about the front which is where most of the bugs hit. My current helmet is a Schuberth C3 and I have found some quarter sized bugs in the top vent which is easy to clean out. Thanks in advance!

Fine here you go revzilla computer "???????"
A shopper on May 28, 2014
BEST ANSWER: Wish I could help, never gave bugs much thought.
I have to wear eyeglasses when riding, day or night. Does this helmet have eyeglass channels built in to the liner to allow for easy eye glass placement? With my current helmet, I had to remove the cheek pieces and basically "restuff" the material to allow for my glasses to slide in easily.
A shopper on Aug 25, 2013
BEST ANSWER: I don't ride with glasses but I just put the helmet on and then slipped on both a pair of wire frame then a pair of horn rimmed reading glasses and both felt fine. There is a channel between the pads that allows for comfortable movement of the frames with no pressure. There is also plenty of clearance when the shield is down.
Are the visor and face shiel included with the XD4 helmet or do I need to purchase one or both of these separately?
A shopper on Oct 7, 2013
BEST ANSWER: Both visor and face shield are included, in fact they are attached on delivery.
is xd4 pin lock ready or do I have to drop more money on a new shield?
A shopper on Sep 30, 2012
BEST ANSWER: It is NOT pinlock ready, however, the airflow is so great in this helmet that I have found it to be less of an issue than my Signet-Q. I immediately purchased a pinlock ready visor and insert, but now that I think of it have never needed to use it.
RE: Arai xd4. My monitor shows little difference between the "Pearl Black" and the "Frost Black." Can I assume pearl means 'gloss' and frost means 'matte?'
mike c on Feb 2, 2016
BEST ANSWER: Im no expert but I do own both color variations in different array helmets. Yes the "frost black" has more of a 'matte' style finish with little depth to the color, while the pearl black could be considered 'gloss', it has lot more depth to the black. Bold and shiny, flat and low luster... Ive got the flat and low luster "frost black" and love it. Hope that helps.
Do you recommend this helmet for naked bike like Kawasaki Z800? Please advise, thanks
A shopper on Apr 1, 2014
BEST ANSWER: I ride BMW G650GS, which has minimal wind protection.
You "feel" the visor at higher speeds, but I rode for and hour at 80MPH no problem. I got used to it.
That being said, I realized that I couldn't live without the visor.
There is a lot of sunshine here and the beak helps to see better in traffic.
You stop on intersection, sun blinds you - no problem. Little move of your head and you can see again.
I will gladly pay the "penalty" of some extra air resistance.
Heck, my neck muscles will probably grow. ;)
What makes this better than the Shoei DS Hornet?
A shopper on Feb 11, 2014
BEST ANSWER: I have a long oval head and the Arai fit my head better. Even the Arai is not perfect. I spoke to the Arai rep at the Progressive motorcycle show and told him they need to make a long oval XD-4 and a modular helmet. He said that he hears that question everywhere he goes. The xd-4 is a very good helmet however. It is louder than my Arai Profile and my Shoei Multitec.
I'm becoming more and more interested in helmets with the visor, or the dual sport style. my concern is i ride a speed triple with little wind protection and speed is my friend. Will the visor on the top create an uncomfortable amount of resistance?
kimerer25 on Nov 29, 2015
BEST ANSWER: The helmet works really well when I ride off road, and up to 60 mph or so. I would not ride this over 60 mph and expect it to be comfortable. It's not neck snapping, but not like my street helmets.
