The Arai Quantum-X Helmet in Diamond White is designed for riders who prefer a round oval fit, making it an excellent choice for head shapes that are slightly wider rather than elongated. Part number 0101-17712 features an interior liner with thicker front and rear pads and thinner side pads for a secure, comfortable fit. Arai’s attention to shell design, ventilation, shield operation, and noise control makes the Quantum-X a practical choice for everyday street riding and long-distance use.
The Variable Axis System (VAS) shield system lowers the shield pivot point to create a smoother shell surface around the critical temple area. This design helps improve the helmet’s ability to glance off impacts while supporting Arai’s focus on protective performance. The improved VAS shield latch securely captures the shield to help prevent unexpected opening, while its larger design makes shield operation intuitive. The included VAS-Max Vision shield accepts a VAS-MV Pinlock lens, and a Pinlock 120 MaxVision lens is included to help reduce fogging in changing riding conditions.
Ventilation is managed by QVF three-position intake ducts and QVR exhaust ducts, providing effective airflow for comfort during the ride. The side vent continues functioning as an exhaust vent even when the front shutter on the top duct is closed. FCS® cheek pads use a contoured shape, multiple foam densities, and a foam spring to cradle the face, simplify helmet removal, 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 combines multiple materials and construction techniques for a balanced blend of performance and value.
