The Arai Quantum-X Helmet in White, size 2XL, is designed for riders who prefer a round oval fit with slightly more width than an elongated helmet shape. Its interior liner uses thicker front and rear pads with thinner side pads to provide a comfortable, supportive fit. The helmet’s egg-shaped profile and integrated chin cover help promote smooth airflow while reducing wind noise from below. Part number 0101-17656 identifies this Arai Helmets configuration.
The Quantum-X features Arai’s Variable Axis System (VAS) shield system, which lowers the shield pivot point to create a smoother shell surface around the critical temple area. This design helps improve glance-off capability and supports more effective impact energy management. The VAS latch securely captures the shield when closed to help prevent unexpected opening, while its larger design allows intuitive shield operation and supports the shield’s de-mist function. A VAS-Max Vision shield is included and accepts a VAS-MV Pinlock lens, with a Pinlock 120 MaxVision lens included for improved fog resistance.
Ventilation is managed by QVF three-position intake ducts and QVR exhaust ducts to support efficient airflow during rides. The side vent continues functioning 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 reduce wind noise. The water-repellent ES chin cover comes installed and further enhances airflow around the lower helmet while increasing mouth-area exhaust. The PB-SCLC shell combines multiple materials and construction techniques to deliver a strong, performance-focused design with everyday riding versatility.
