The Arai Quantum-X Helmet in Diamond White is designed for riders who prefer a round oval helmet fit, with slightly more width than an elongated head shape. Arai achieves this profile with an interior liner that combines thicker front and rear pads with thinner side pads for a secure, comfortable fit. The included FCS® cheek pads use multiple foam densities and a supporting foam spring to cradle the face, simplify helmet removal, and help reduce wind noise. The water-repellent ES chin cover comes installed to enhance the helmet’s Egg Shape profile while smoothing airflow and reducing noise from below.
The Quantum-X features Arai’s Variable Axis System (VAS) shield system, which lowers the shield pivot point by an average of 24 mm. This creates a smoother shell surface in the critical temple area to help improve glance-off performance and reduce the transfer of impact energy into the helmet. The improved VAS latch securely captures the shield to help prevent unexpected opening, while its larger design supports intuitive operation and includes a de-mist function. A VAS-Max Vision (VAS-MV) shield is included and accepts the supplied Pinlock® 120 MaxVision™ lens for improved fog resistance in changing riding conditions.
Airflow is managed by QVF three-position intake and QVR exhaust ducts for effective ventilation while riding. The side vent continues to function as an exhaust vent even when the front shutter on the top duct is closed, helping maintain air movement across a range of conditions. The helmet uses Arai’s Peripherally Belted Super Complex Laminate Construction (PB-SCLC) shell design, combining multiple materials and construction techniques for a strong, functional shell. With its round oval fit, advanced shield system, included anti-fog lens, and practical ventilation features, the Arai Quantum-X Helmet delivers a refined option for everyday street and touring riders. This medium Diamond White model is identified by Part Number 0101-17713.
