Details

The Arai Defiant-X Helmet is the original Arai Defiant PLUS many changes making this helmet even better, both in style and in protection. What is different? Building upon the original Defiant, the Defiant-X smooths out its predecessor's aggressive lines to produce a bold yet refined helmet. The updated cheek pads feature the Facial Contour System to provide a snug yet comfortable fit. With the newer Free Flow System  Arai guides air underneath the helmet improving overall ventilation for the perfect amount of Airflow to match the weather in which you are riding. The Arai Defiant-X is the result of Arai's world renowned quality and attention to detail with unchallenged comfort, protection and style.

 

  • Strong round smooth old school PBcLc (Peripherally Belted, complex Laminate construction) shell
  • Shell constructed from the layering of many materials with proprietary adhesives which allow for a larger eyeport
  • Protection is further enhanced by the Super Fiber Belt that strengthens the shell like the bands of a barrel
  • The distinct belt resists the widening of cracks encountered in an impact while evolving Arai's most advanced shell in strength, weight, and protection
  • Intermediate oval head shape
  • To enhance the strong shell design, the open close shutters are placed inside of the helmet for superior ventilation
  • Air can flow over the mouth for a demist function by opening and closing these shutters
  • To further enhance internal airflow, air channels originally designed for the Crosair-X were borrowed, updated and connected to the exhaust ports on the chin bar allowing for increased airflow, reduced fogging and overall increased ride comfort
  • Dual functioning front duct when open, allows air to flow freely into the helmet
  • When closed, the QVF-2 duct prevents air from entering and functions as an exhaust duct, allowing hot air to be pulled from the helmet interior
  • The upper QVR-2 rear duct has three vent holes controlled by a single gate, when open air is pulled from the helmet interior
  • Additional side and neckroll exhaust port keeps the back of the head comfortably by removing hot air as well
  • Anti-microbial material, uses a low acidic fabric to help maintain a balanced pH level with the skin
  • Anti-microbial fabric is also odor resistant helping the helmet stay fresher longer in between cleanings
  • 5mm peel away and side temple pads on both sides of headliner and in the FCS cheek pads gives you the option of 5mm more of interior width and yet another level of fit customization no other helmet brand offers
  • Fixed chin curtain is larger and helps to block out wind noise and control airflow efficiency under the helmet by creating a low pressure zone in the mouth area, helping to draw breath out of the helmet
  • Fixed chin curtain is made with water repellent materials to block rain and will not weigh down with water
  • Meets or exceeds SNELL and DOT certifications

General Sizing Information

If you are unsure about your size, compare your body measurements to the charts provided to determine the correct fit. These charts will give you a good idea of the size to order, but be sure to read special sizing information that may accompany an item description. Some merchandise dimensions may vary from the averages charted here.

Head Circumference

Head circumference measurements should be a starting point only in determining your helmet size. Determining the best possible fit should be from actual test fittings of Arai's various interior fit packages, with optional interior lining and cheek pad thicknesses to find the best fit.

Interior Liners and Cheek Pads

Optional interior liners and cheek pads of different thicknesses allow you to custom fit your Arai helmet. When ordering a liner of a different thickness, start with the Lining Code that matches your helmet size, then specify the desired thickness. For example, an optional 5 mm liner for a large helmet would be specified as a "III - 5 mm" liner.
