The Arai Helmets Quantum-X Helmet in Pearl Black, size XL, is designed for riders who prefer a slightly wider, round-oval head shape rather than a longer, narrow profile. Its interior liner combines thicker front and rear pads with thinner side pads for a supportive, balanced fit. The helmet includes Arai’s water-repellent ES Chin Cover, which helps enhance the shell’s egg-shaped profile while smoothing airflow, reducing wind noise from below, and improving exhaust flow around the mouth area.
Built for confident street and touring use, the Quantum-X features the Variable Axis System (VAS) shield system. By lowering the shield pivot point, the design creates a smoother shell surface around the temple area to help improve glance-off performance. The improved shield latch captures and secures the shield closed, while the larger latch supports intuitive, smooth operation. The included VAS-Max Vision (VAS-MV) shield accepts a Pinlock lens, and a Pinlock 120 MaxVision lens is included to help reduce fogging in changing riding conditions.
Ventilation is managed through QVF three-position intake and QVR exhaust ducts. The side vent continues functioning as an exhaust vent even when the front shutter on the top duct is closed, helping maintain airflow control. FCS cheek pads use contoured shaping, multiple foam densities, and a foam spring to cradle the face, simplify helmet removal, and help reduce wind noise. The Peripherally Belted Super Complex Laminate Construction (PB-SCLC) shell combines multiple materials and construction techniques for a strong, refined helmet platform.
