After creating the first Dual Sport helmet back in the late 90's, evolving it into a universal design that finds itself at home in practically all forms of motorcycling, what else did you expect from Arai, but simply more of what works!
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 5mm peel away temple pads, and Patent-Pending FCS cheek pad design, also with a 5mm peel away micro fit 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. 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 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.
*Note*: It is important for all new XD series owners to familiarize themselves with the performance characteristics of the helmet, beginning at slower speeds, increasing slowly up to full legal highway speeds.
*Note*The peak/visor supplied is not suitable for high-speed use where air striking a side or main surface of the peak may cause difficulty in returning the head to a forward and/or level position.
Item Details
New exhaust ports added to the top diffuser vents nearly double the airflow while using the same (4) 10mm vent holes in the helmet shell.
The ability to increase performance from existing designs is typical of Arai’s evolutionary thinking.
New shell shape for better aerodynamic stability at higher street speeds, works in concert with the high-flow peak and new side cowl vents.
New chin vent with more intake ports.
Larger sculpted side cowl vents improve ventilation efficiency as well as helmet stability at higher speeds.
The 5mm peel-away temple pads add another level of customization, providing a little extra width when needed.
Enhanced customer benefits like micro fitment interior, without the need to purchase extra interior components, underscores Arai’s commitment to our customers.
New FCS (Facial Contour Support) cheek pad design.
Patent pending design adds just the right amount of pressure when needed while being worn, but seamlessly "get out of the way" when putting on and taking off the XD’4.
Arai’s trademark Brow vents have been added to the XD’4, 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 Pin-Lock Anti-Fog lens inserts.
Multi-Density (up to 5 in some models), Single piece EPS liner provides exceptional impact energy management, while keeping the overall size and weight of the helmet to a minimum.
Fully removable/replaceable/washable Interior: Comfort head liner, Cheek pads, Chinstrap covers.
Dry-Cool technology keeps you dry & cool for greater comfort.
Meets or exceeds Snell and D.O.T. standards.
