Arai XD4 XD-4 Mesh Helmet

Features

• New Shell Shape
• For better aerodynamic stability at higher street speeds, works in concert with the high-flow peak and new side cowl vents
• Redesigned Peak
• Arai's Twin-Cam Shield Pivot System enables the shield to operate fully beneath the mounted peak without protruding, staying low when it's raised, allowing the peak to be mounted lower, resulting in better aerodynamics and a better appearance; redesigned for even better stability and airflow; tested to perform up to street-legal speeds; to be used in combination with the peak, alone without the peak or with the peak and no shield
• Brow Vents
• Arai's trademark brow vents have been added to the XD4, giving it the final piece of the ventilation puzzle
• Redesigned 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 helmet
• Removable Liner with Microfit Ability
• Features Arai's innovative Dry-Cool lining material which utilizes micro water cells to improve moisture and heat transfer from your head into the airflow around Arai's exclusive Space Frame Liner
• Redesigned 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
• Emergency Cheek Pad Release System
• 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 - making helmet removal much easier for trained medical personnel
• Shell Construction
• Arai's decades of experience, research, testing, comparison and evaluation has led to the conclusion that fiberglass-based construction is best at performing a helmet shell's main job - spreading impact energy over the widest area through strength, structural integrity and impact flexibility; 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 a single piece; the direct-fused contact area that each EPS cell shares with its neighboring cells creates a mutual support - as one cell is crushed under impact, the surrounding cells assist with the energy absorption
• Peak Safety Note
• The visor/peak supplied 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.
