Arai XD4 Diamante Red/White Helmet
Product Description

The XD4 Ė After creating the first dual sport helmet back in the late 90ís, evolving it into a universal design that finds itself at home in practically all forms of motorcycling, what else did you expect from Aria, but simply more of what works!

Offering 3 distinct configurations, allowing the user to choose which works best for them, the new XDí4 is similar in appearance but greatly improved in all-around performance as compared to the XDí3.

The combination of the new comfort headliner, with microfitting 5mm peel away temple pads, and patent-pending FCS cheek pad design, also with a 5mm peel away micro feature, add a new dimension to the concept of helmet fit and individual customer satisfaction.

Proper fit, comfort, and stability cannot be defined by one aspect of a helmets interior. It requires a coordinated understanding of the bigger picture.

The patent-pending design of the FCS cheek pads turns the already impressive Arai cheek pad design into a comprehensive and integral part of the helmets overall fit and function.

It takes a commitment to making a product better and not simply accepting good enough, even when what you already have is generally regarded as being the best.

New Shell Shape
New shell shape for better aerodynamic stability at higher street speeds, which works in concert with the high-flow peak and new side cowl vents.

Re-Designed Peak
One of the keys to the original XDís uniqueness was Araiís Twin-Cam Shield Pivot System that enables the shield to operate fully beneath the mounted peak without protruding. The shield stays low when itís raised, allowing the peak to be mounted lower, resulting in better aerodynamics and a better appearance. The new XD4ís peak has been re-designed for even better stability and airflow Ė and tested to perform up to street-legal speeds. The shield system is also designed for the shield to be used in combination with the peak, alone without the peak, or with the peak and no shield, as desired.

Brown Vents
Araiís trademark brow vents have been added to the XDí4, giving the XD series the final piece of the ventilation puzzle. As with all Arai street helmets, an optional shield with pins is available for use with optional Pinlock Anti-Fog inserts.

Re-Designed Chin Vent
The XDí4 has an all new chin vent design with more intake ports, this along with larger sculpted side cowl vents help improve ventilation efficiency as well as helmet stability at higher speeds.

FCS Cheek pad
New FCS (Facial Contour Support) cheek pad design adds just the right amount of pressure when needed while being worn, but seamlessly ďgets out of the wayĒ when putting on and taking off the XDí4. Another example of Arai's attention to all aspects of fit.

Removable Liner with Microfit Ability
The XDí4 also features Arai's innovative Dry-Cool lining material. The Dry-Cool liner actually utilizes micro water cells to improve moisture and heat transfer from your head into the airflow around Arai's exclusive space frame liner. Along with 5mm peel away temple pads that add another level of customization, providing a little extra width when needed.

Re-Designed Ventilation
New exhaust ports added to the top diffuser vents nearly double the airflow, while using the same four 10mm vent holes in the helmet shell. Along with larger sculpted side cowl vents these two features help improve ventilation efficiency as well as helmet stability at higher speeds.

Emergency Cheek-Pad Release
Yet another Arai innovation, first introduced on the 2007 VX-Pro3 dirt helmet. From Araiís decades-long commitment to rider safety comes the first Emergency Cheek-pad Release Design created specifically for motorcycle helmets. Developed to allow easier access to an injured rider, the XD4ís cheek-pads slide out easily via the integrated pull-tabs built into the underside of the cheek-pad - which makes helmet removal much easier for trained medical technicians.

Shell Construction
These days, there are almost as many ďrevolutionaryĒ shell-construction materials as there are new helmet brands. Araiís decades of experience, research, testing, comparison and evaluation has led us to conclude that fiberglass-based construction is best at performing a motorcycle-helmet shellís main job Ė spreading impact energy over the widest area through strength, structural integrity and impact-flexibility. The XD4ís CLC (Complex Laminate Construction) shell utilizes Araiís proprietary aerospace fiberglass technology to achieve a strong, flexible shell in a very lightweight package.

One-Piece EPS Liner
Araiís multi-density EPS liner is like no other, comprised of up to five different densities in some models Ė and molded into a single piece. Arai pioneered this technology more than 20 years ago and is still, to our knowledge, the only helmet offering a single-piece hybrid liner and its unique benefit: the direct-fused contact area that each EPS cell shares with it neighboring cells creates a mutual support - as one is crushed under impact, the surrounding cells assist with the energy absorption. Liner pieces that are simply fitted or glued together cannot rely on such a high-level support bond.

Interior Shape
The XDí4 has Araiís intermediate oval shell shape. This shape is designed for the rider whose head has a front-to-back dimension that is longer than the side-to-side dimension.

Special note (CAUTION): Maybe this is common sense, but because of the world we live in our lawyers say that this needs to be said: The visor/peak supplied with the XD helmet is not suitable for high-speed use. At such speeds air catching a side or main surface of the peak may cause difficulty in returning the head to a forward and/or level position. To understand and prepare for this possible effect, you should first try to experience it at low speeds, gradually increasing speed so that you will know what to expect and determine when the peak should be removed for higher-speed riding.
