The Arai Helmets Quantum-X Helmet combines a rider-focused fit with advanced shell and shield design for confident street performance. Part Number 0101-15731 features a round oval interior shape developed for riders whose heads are slightly wider rather than elongated. The interior liner uses thicker front and rear pads with thinner side pads to create a secure, comfortable fit while supporting long-duration riding comfort. The fluorescent yellow finish adds high-visibility style to the helmet’s functional design.
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 glance-off ability and supports more effective impact energy management. The VAS shield latch captures and holds the shield securely closed to help prevent unexpected opening, while its larger design enables intuitive operation and supports the shield’s de-mist function. The included VAS-Max Vision shield accepts a VAS-MV Pinlock lens, and a Pinlock 120 MaxVision lens is included for improved fog resistance.
Ventilation performance comes from the QVF three-position intake ducts and QVR exhaust ducts, which work together to promote efficient airflow 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, multiple foam densities, and a supporting foam spring to cradle the face, simplify helmet removal, and help reduce wind noise. A water-repellent ES chin cover is 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 balance performance and value in a durable Arai design.
