The Arai Quantum-X Helmet in Aluminum Silver is designed for riders with a round oval head shape, offering a comfortable fit for heads that are slightly wider rather than elongated. Its interior liner combines thicker front and rear pads with thinner side pads to support a secure, balanced fit. Arai Helmets part number 0101-18163 identifies this XS-size configuration, making it easy to match with the appropriate riding gear and helmet accessories.
The helmet 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 improved shield latch captures and securely holds the shield closed while providing intuitive operation. The larger latch also supports convenient use of the shield’s de-mist function. A VAS-Max Vision (VAS-MV) shield is included and accepts a Pinlock 120 MaxVision lens, which is also supplied for improved fog resistance in changing riding conditions.
Ventilation is managed by QVF three-position intake and QVR exhaust ducts for effective airflow while riding. The side vent continues to function as an exhaust vent even when the top duct’s front shutter is closed. FCS® cheek pads use a contoured shape, multiple foam densities, and a foam spring to cradle the face, help reduce wind noise, and make helmet removal easier. A water-repellent ES chin cover comes installed to enhance the helmet’s egg-shaped profile, smooth airflow, increase exhaust from the mouth area, and reduce wind entering from below. The PB-SCLC shell uses multiple materials and construction techniques to provide a balanced combination of protection-focused performance, durability, and value.
