The Arai Helmets XD-5 Nation Adventure Helmet in Medium is designed for riders who want confident protection, adaptable ventilation, and clear visibility across changing road and trail conditions. Manufacturer part number 0140-0585 and vendor part number 0140-0585 identify this model. The XD-5 uses Arai’s PB-cLc² shell construction, with a Super Fiber belt reinforcing the forehead area to support the shell’s strength and help improve its ability to glance off impacts.
The VAS-A Shield System lowers the shield pivot position to help preserve shell integrity while providing a wide field of view. The VAS-A Max-Vision Shield supports excellent visibility, and the optional Pinlock insert is designed to resist fogging across the viewing area in demanding conditions. The Nation peak uses one screw on each side and can be installed or removed without tools, making shield and peak changes faster and easier. Its adjustable design helps manage sunlight, airflow, and buffeting for a more comfortable ride.
Ventilation is managed through the mouth shutter, inner shutter, front logo duct, and rear airflow features. The mouth shutter admits fresh air without relying solely on mesh vents, while the inner shutter lets riders direct airflow toward the shield to help reduce fogging or toward the mouth for increased ventilation. The front logo duct allows forehead airflow without compromising the protective structure and is designed to remain effective across different riding positions. An adventure-oriented AR spoiler helps reduce turbulent-air fatigue and draw warm air away from the crown area. An odor-resistant interior adds comfort during extended use.
The Arai Helmets XD-5 Nation is intended for adventure and dual-sport riders seeking a versatile helmet with adjustable airflow, a broad field of view, and adaptable sun and shield management. Select the Medium size for riders whose head measurement corresponds to Arai’s Medium fit specification. Always confirm sizing and fitment with the manufacturer’s current size chart before use.
