The Arai Quantum-X Helmet in Diamond White is designed for riders who need a comfortable round oval fit and dependable performance for everyday street riding. Part number 0101-17711, this XS helmet uses an interior liner with thicker front and rear pads and thinner side pads to accommodate head shapes that are slightly wider rather than elongated. The refined interior helps provide a secure, balanced fit while supporting long-term comfort on the road.
The Variable Axis System (VAS) shield system lowers the shield pivot point by an average of 24 mm, creating a smoother shell surface in the critical temple area. This design helps improve the helmet’s ability to glance off impacts and reduce energy transfer into the helmet. The improved shield latch captures and securely holds the shield closed while making shield operation intuitive, including when using the de-mist function. The included VAS-Max Vision shield accepts a VAS-MV Pinlock lens, and a Pinlock 120 MaxVision lens is included for added fog resistance.
Ventilation is managed by QVF three-position intake and QVR exhaust ducts that support effective airflow during changing riding conditions. 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, 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, improve exhaust from the mouth area, and reduce wind entering from below. The PB-SCLC shell combines multiple materials and construction techniques for a strong, functional design with a refined finish.
