MO Tested: Arai XD4 Helmet Review

It may be a millennial for me, but I am always grateful to Arai Helmet for the history of my company and the fact that the lids are handmade in Japan. The terms “heritage” and “handmade” have attracted the attention of my generation. But in the case of Arai, you don’t have to rely on hip marketing to seduce stakeholders. The proof is in pudding, as they say, and Arai has provided it extensively since the 1950s. The Arai lid is on the heads of the world’s most erry racers from MotoGP to Dakar and can also be found in less interesting four-wheel sports like F1 (I’m a kid, I’m a kid).

what’s new?

The Arai XD4 replaced its predecessor (XD3) in 2012 and has remained largely unchanged since then. When the XD4 hit the market, Arai insisted on a better ventilation system, including a slight change to the diffuser for the entire helmet and a new shield with a blow vent to enhance the air-cooling effect of the ram. The XD4’s internal pads allow for additional adjustments, allowing the user to reduce the foam thickness by 5mm on the sides of the teak pad and crown. It also includes an emergency quick removal tab for extracting cheek pads in case of misfortune.

In addition to all of this, the helmet’s shell shape has also been slightly modified to be available in five shell sizes (XS, SM, MD-LG (same shell), XL, XXL), the smallest possible. The lightest helmet is secured. ..

It is said that in 2018, there was a slight aerodynamic change at the peak, the internal fabric was upgraded to match the Corsair fabric, and an anti-fog coating shield with several shade options became available. increase.

First Look

At first glance, the first thing you notice is the quality of the finish and graphics. The vision graphic on my helmet has a matte finish with a few metal spots throughout. The graphics are elegantly layered and I use the word perfect considering the other two Arai helmets I own, but when I look directly at the front of the XD4, I see an asymmetrical graphic (helmet). I didn’t notice until I was sitting on top of me) The desk when I entered this review).

Depending on whether you have checked other helmets on the market, if you get the XD4 right away, you may then notice the weight of the XD4. In terms of weight, Arai is in the middle of the three adventure helmets I’ve been using recently and weighs 3 pounds and 9.9 ounces (1641 g). The other helmets, the Klim Krios and the Shoe i Hornet X2, tilt at 2 lbs 15.7 ounces (1352 g) and 3 lbs 15 ounces (1786 g), respectively. Considering all the helmet crops, including on-road, off-road, and somewhere in between, the XD4 isn’t the lightest helmet ever, but it’s almost not the heaviest.

Arai uses the R75 shell shape for its visual characteristics, along with EPS liners of various densities inside it to properly absorb the impact. Even the comfort liner itself uses multiple density foams to ensure the safest and most comfortable fit.

Arai Helmets sold in North America meet both DOT and Snell M2020 tests. Penetration testing is required to obtain Snell certification. This adds weight (and often stiffness) to the helmet in all cases I know of. The XD4 shell is made of a layer of carbon and fiberglass that is hand-laid using Arai’s unique resin blend, but the helmets sold on the Stateside are heavier than those found on other markets. prize.

Pull the orange emergency quick release tab to easily remove the teak pad after an unfortunate incident. You can also pull down the small chin curtain to limit the air flow from under the helmet.

Wearing a helmet reminds me why everyone is talking about the comfort of an Arai helmet. The XD4 is thought to fit a medium oval head shape, but tends to have a soft pillow-like liner that adapts well to slight changes in head shape, making it comfortable over a wide range of melons. Will be. Like other modern Arai helmets, the XD4 features cheek pads and crown pads that allow you to remove the 5mm foam layer to customize the fit.

Installing the Cardo Packtalk Bold Bluetooth Communicator did not change the fit at all. The teak pad notch makes the communication unit easy to install and fits comfortably.

The XD4 is a comfortable helmet that is easy to put on and take off all day long. Another feature you’ll notice about the Arai XD4, which applies to most ADV helmets, is the giant eyeport. I think this is one of the reasons why adventure helmets have come to be used on a daily basis. It is difficult to match the peripheral vision of an adventure helmet. Of course, this also allows users to wear goggles on the XD4 off-road. This is most comfortable when you remove the visor.

If you think of the Arai XD4 as a universal helmet, it comes in three configurations and is excellent for its intended use. First, you’re ready to wear it, attach a peak, attach a visor, and work on your commute to Starbucks just as you would conquer Tierra del Fuego. You can then remove the visor, reattach the peak (attach the visor with the same plastic screws that attach the peak), and use goggles to ride off-road. Ara MX. Third, removing the peak and reattaching the visor allows for a more aerodynamic setup for street riding and better peripheral vision. This may be a strange or unusual configuration, but I’ve noticed that many city riders use it. That makes sense and makes Arai’s ADV lid even more convenient. This is perfect for a $ 740 helmet (vision graphic).

On the street or under the trail

The recent adventure helmet harvest does a surprisingly good job of being aerodynamically good enough not to turn your head into a sail at high speed. Did you notice the peak while riding? Yes. Is the XD4 the most aerodynamic adventure helmet I’ve used? No. However, from naked bikes to adventure touring machines, there were no problems to regret using a helmet.

Finishing plates on both sides provide a sophisticated look with or without peaks attached.

The peak of the XD4 catches some wind, and depending on the motorcycle I’m riding, I’m between the point of wind caught underneath and the point of pulling it up, pulling it up, and pushing it down. You may notice wobbling. On an adventure bike, I don’t really care much.

The rear diffuser vents on the Arai XD4 can be easily replaced by pressing the red tab on the vent closure mechanism on the right. This will cause the diffuser to pop out of the vent and when the new piece is replaced, pull the red tab back in place and it will lock securely.

With the roads gone and the terrain technically changed, we found that the XD4’s practical ventilation system worked very well. All three large chin bar vents are openable and closable in the center, both inside and outside the helmet for fine adjustment. You can open the vents on the forehead visor to send air directly to the forehead. The upper vent can be easily opened and closed with a switch-type toggle above the air intake. I noticed that the front facing vents at the top work best, as when the summits are pushed to the highest position, they appear to block them almost completely when they are low. The two large exhaust vents on the top back of the helmet can be opened and closed in the same way. There are two lower vents near the bottom of the helmet and a channel at the bottom of the neck roll to guide the airflow from the helmet.

Note the foggy building at the bottom of the visor.

The visor itself may really be one of my biggest pitfalls with Arai Helmet. They all feel flimsy when compared, and helmet locking mechanisms like the Corsair X don’t always offer consistent ease of use. That said, I actually had only one problem with Arai Shield. Ram-X When the shield falls in your hand while trying to adjust the shield while riding. The visor isn’t as sturdy as the other adventure helmets in my stable, but it works well and looks transparent, but what’s both the transparent visor and the colored visor I used (and it’s a kind of big one) The worst that is clouding. Arai currently offers anti-fog and pin-lock compatible versions of accessory visors (clear only, pin-lock inserts sold separately), but with a starting price of $ 610, pin-lock compatible visors and inserts are included. Included in the package I want to be.

Adventure is booming

In 2012, when the XD4 hit the market, there weren’t many competitors. The adventure scene was just starting to get hot. Today, in 2021, adventure motorcycles are hotter than ever, and the competition to equip these adventurous domes is about as hot.

Over 15 helmet manufacturers in the United States sell ADV or “dual sports” lids. Despite the last “major” update of the XD line in 2012, Arai’s XD4 remains a top candidate on the market. It’s one of the most expensive. There are two ways to see it, but it can be discussed for camps that say “don’t fix it if it’s not broken” or for those who want some innovation. Personally, I want a lightweight XD5 with a pin lock compatible shield with an insert in the box. You can also check the aerodynamics of the peak again. Competition has never forced Arai to take drastic measures. The evolution of the XD line is an example of how Japanese companies are sticking to what they consider to be the best approach. For now, I’ll continue to wear the XD4, but I’m hoping that the next evolution from Arai will be just above the rising sun’s horizon.

Frequently Asked Questions

Which goggles fit the Arai XD4?

One of them! At least 100% Racecraft +, Klim Viper Pro, Fly Zone Pro, whatever brand I’m sitting around. Goggles fit best with the visor completely removed, but can be worn without removing the visor, but the seal around the rider’s face is not suitable for dust protection.

Which Bluetooth communicator is compatible with Arai XD4?

One of them again! Modern communicators like the Cardo Packtalk Bold and Sena units should fit nicely into the Arai XD4. The medium helmet I have fits me perfectly and I didn’t see any difference in fit or comfort after installing Packtalk Bold.

What is an Adventure Bike Helmet?

Adventure helmets combine the world of street and off-road functionality. ADV helmets like the Arai XD4 are designed to be tightly sealed for weather resistance when touring and can be opened for ventilation like an off-road lid to tackle more dangerous terrain.
