Offering 3 distinct configurations, allowing the user to choose which works best for them, the new XD4 is similar in appearance but greatly improved in all around performance, as compared to the XD3.
The combination of the new comfort headliner, with micro-fitting 5 mm peel away temple pads, and patent-pending FCS cheek pad design, also with a 5 mm 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 helmet's interior. You require 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 helmet's 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, works in concert with the high-flow peak and new side cowl vents.
Re-designed peak: One of the keys to the original XD's uniqueness was Arai's twin-cam shield pivot system that enables the shield to operate fully beneath the mounted peak without protruding. The shield stays low when it's raised, allowing the peak to be mounted lower, resulting in better aerodynamics and a better appearance. The XD4's peak has been re-designed for even better stability and airflow - 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.
Brow vents: Arai's trademark brow vents have been added to the XD4, giving the XD series the final piece of the ventilation puzzle.
Re-designed chin vent: The XD4 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 "gets out of the way" when putting on and taking off the XD4. Another example of Arai's attention to all aspects of fit.
Removable liner with micro-fit ability: The XD4 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 5 mm peel-away temple pads add another level of customization, providing a little extra width when needed. Enhanced customer benefits like micro fitment interior.
Re-designed ventilation: New exhaust ports added to the top diffuser vents nearly double the airflow, while using the same four 10 mm 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 System: Yet another Arai innovation, first introduced on the VX-Pro 3 dirt helmet. From Arai's 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 XD4's 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 "revolutionary" shell-construction materials as there are new helmet brands. Arai's decades of experience, research, testing, comparison and evaluation has led them to conclude that fiberglass-based construction is best at performing a motorcycle-helmet shell's main job - spreading impact energy over the widest area through strength, structural integrity and impact-flexibility. The XD4's CLC (Complex Laminate Construction) shell utilizes Arai's proprietary aerospace fiberglass technology to achieve a strong, flexible shell in a very lightweight package.
One-piece EPS liner: Arai's multi-density EPS liner is like no other, comprised of up to five different densities in some models - and molded into single piece. Arai pioneered this technology more than 20 years ago and is still, to their 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 its 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).
Intermediate Oval: The XD4 has Arai's Intermediate Oval (IO) shell shape. This shape is designed for the rider whose head has a front-to-back dimensions that is longer than the side-to-side dimensions.
Meets or exceeds SNELL and DOT standards.
Special note: The visor / peak supplied with the XD4 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.
