Arai Defiant X Helmet

The Arai Defiant-X Helmet is steeped in style and protection. Building upon the original Defiant, the Defiant-X smooths out its predecessor's aggressive lines to produce a bold yet refined helmet. Made with a PB-cLc shell, which features technology developed in the highest level of racing in the world. Safety is further enhanced by the Super Fiber Belt that strengthens the shell like the bands of a barrel, this distinct belt resists the widening of cracks encountered in an impact while evolving Arai's most advanced shell in strength, weight, and protection. Facial Contour System cheek pads provide a snug yet comfortable fit. Arai's Free Flow System guides air underneath the helmet to improve overall ventilation for hot weather riding. The Arai Defiant-X is the result of Arai's legendary quality and attention to detail. Its comfort, protection and style are a triple threat that is tough to beat.

PB CLC Shell:

  • Peripherally Belted - Complex Laminate Construction shell
  • Design combines multiple materials and techniques created internally by Arai that deliver both performance and affordability
  • Shell has superb tensile strength due to a variety of carefully-positioned materials and light weight resin
  • Multi density EPS

VAS Shield System:

  • VAS (Variable Axis System) shield and side pods are exclusive to the Arai Corsair X Helmet
  • Variable axis (moving pivot point) allows shield mount position to be lower than most helmets
  • Dual function lever releases both the side pod and the face shield for quick and simple face shield removal

VAS Shield Latch System:

  • Captures and holds the face shield closed securely
  • Provides a de-mist position to slightly crack the shield open
  • Larger latch design allows for intuitive and seamless operation

VAS V MV Shield:

  • VAS MAX Vision shield
  • Provides excellent visibility in all seasons
  • Includes clear anti-fog Pinlock insert

Ventilation:

  • Free Flow System (FFS) ventilation creates airflow under the helmet to reduce wind noise and turbulence while increasing hot air exhaust
  • Dual intake front vents, side exhausts and one-piece rear exhaust
  • Three position chin vent
  • Neck vent exhaust
  • Vents are easy to operate with gloved hands

Interior:

  • Facial Contour System (FCS) offers a snug fit by using a foam spring support in the cheek pad that compresses and rebounds without excessive pressure
  • Fully removable and soft interior liner with 5mm peel-away layer for a perfect fit
  • Speaker pockets
  • Made from odor-resistant material which helps maintain neutral acidity levels close to human skin
  • Non-removable chin curtain

Safety:

  • Snell 2020 and DOT certified
  • Double D-ring strap
