The Arai Quantum-X Helmet combines advanced protection, refined aerodynamics, and rider-focused comfort in a versatile street helmet. Designed for riders with slightly wider, round-oval head shapes, its interior liner uses thicker front and rear pads with thinner side pads for a secure, balanced fit. The Black Frost finish provides a clean, understated appearance, while the carefully shaped shell supports smooth airflow and comfortable long-distance riding.
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 improves the helmet’s ability to glance off impacts and helps reduce energy transferred into the helmet. The improved VAS latch captures and securely holds the shield closed while allowing intuitive operation, including convenient use of the de-mist function. The included VAS-Max Vision shield accepts a Pinlock lens, and a Pinlock 120 MaxVision lens is included for enhanced fog resistance in changing riding conditions.
Ventilation performance comes from QVF three-position intake and QVR exhaust ducts, providing effective airflow management 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 contoured shaping, layered foam densities, and a foam spring to cradle the face, improve on-and-off convenience, and help reduce wind noise. 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 construction combines multiple materials and manufacturing techniques for dependable performance and practical everyday value.
