The Arai Helmets XD-5 Discovery helmet is designed for adventure riders who demand dependable protection, versatile airflow control, and a wide field of vision. This Large helmet features Arai’s PB-cLc² shell construction, which combines multiple materials for a strong, lightweight design. A Super Fiber belt reinforces the forehead area of the shell, helping improve protection while supporting the helmet’s lowered VAS-A shield system.
The VAS-A Max-Vision shield preserves the broad visibility expected from the XD platform, while the optional Pinlock® insert helps resist fogging across the viewing area in challenging conditions. The peak is engineered to improve high-speed airflow, provide a wider range of sun-blocking adjustment, and reduce buffeting. Its one-screw-per-side design allows quick removal and installation, and the shield can be changed without tools for convenient riding-condition adjustments.
Ventilation is managed through the mouth shutter, inner shutter, front logo duct, and crown ventilation system. The mouth shutter increases fresh-air intake without relying solely on mesh vents, while the inner shutter lets riders direct airflow toward the shield for fog reduction or toward the mouth for increased ventilation. The front logo duct provides airflow that remains effective regardless of riding position. An adventure-focused AR spoiler helps reduce fatigue caused by turbulent air and assists in drawing warm air from the crown area. The odor-resistant interior supports comfort during extended rides.
Designed for adventure motorcycle use, the Arai Helmets XD-5 Discovery helmet combines road-ready visibility, adjustable ventilation, and aerodynamic refinement in a distinctive Orange Frost finish. This model is sized Large and is identified by manufacturer and vendor part number 0140-0437.
