The Arai Quantum-X Helmet in Diamond Black is designed for riders who prefer a round oval fit, with an interior liner that combines thicker front and rear pads with thinner side pads. This configuration accommodates head shapes that are slightly wider rather than elongated, providing a secure and comfortable fit for everyday riding and extended trips. The helmet includes FCS® cheek pads with contoured shaping, multiple foam densities, and a supportive foam spring that helps cradle the face, simplify helmet removal, and reduce wind noise.
The Variable Axis System (VAS) shield system lowers the shield pivot point by an average of 24 mm, creating a smoother shell surface around the critical temple area. This design helps improve the helmet’s ability to glance off impacts and reduce energy transfer. The VAS latch securely captures the shield when closed to help prevent unexpected opening, while its larger design supports intuitive operation and includes a de-mist function. The included VAS-Max Vision (VAS-MV) shield accepts a Pinlock® lens, and a Pinlock® 120 MaxVision™ lens is included for improved fog resistance.
Ventilation is managed by QVF three-position intake and QVR exhaust ducts to support effective airflow while riding. The side vent continues functioning as an exhaust vent even when the front shutter on the upper duct is closed, helping maintain consistent ventilation across changing conditions. 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 noise entering from below. The Peripherally Belted Super Complex Laminate Construction (PB-SCLC) shell combines multiple materials and construction techniques for a balanced blend of performance, durability, and value. This Arai Helmets Quantum-X Helmet is identified by Part Number 0101-18173.
