The Arai Helmets Quantum-X Helmet is engineered for riders with slightly wider, less elongated head shapes. Its round oval fit uses an interior liner with thicker front and rear pads and thinner side pads for a secure, comfortable feel. The helmet’s egg-shaped profile is complemented by a water-repellent ES chin cover, which helps smooth airflow, increase exhaust from the mouth area, and reduce wind noise entering from below. Part number 0101-18116 identifies this Steel and Red XS configuration.
The Quantum-X features Arai’s Variable Axis System (VAS) shield system, designed to improve glance-off performance by lowering the shield pivot point and creating a smoother shell surface through the critical temple area. The shield latch securely captures the shield when closed to help prevent unexpected opening, while its larger design supports intuitive operation and includes a de-mist function. The included VAS-Max Vision shield accepts a VAS-MV Pinlock lens, and a Pinlock 120 MaxVision lens is included for enhanced fog resistance in changing riding conditions.
Air management is supported by QVF three-position intake ducts and QVR exhaust ducts for efficient ventilation while riding. The side vent continues to function as an exhaust vent even when the front shutter on the top duct is closed. FCS cheek pads use a contoured shape, layered foam densities, and a foam spring to cradle the face, simplify helmet removal, and help limit wind noise. The Peripherally Belted Super Complex Laminate Construction shell combines multiple materials and construction techniques to deliver a durable design with performance-focused protection. Built for everyday street use and long-distance riding, the Arai Helmets Quantum-X balances fit, ventilation, shield control, comfort, and aerodynamic refinement in a professional full-face helmet.
