The Arai Quantum-X Helmet combines a round oval interior shape with advanced shell and shield technology for riders who need a slightly wider fit from front to back. The interior liner uses thicker front and rear pads with thinner side pads to provide a secure, comfortable feel without the elongated profile of an intermediate or long oval helmet. This Aluminum Silver model is sized XL and identified by part number 0101-18167.
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 performance by reducing areas that can catch on impact. The VAS shield latch securely holds the shield closed while supporting intuitive operation, including easy access to the de-mist function. The included VAS-Max Vision shield accepts a VAS-MV Pinlock lens, and a Pinlock 120 MaxVision lens is included for enhanced fog resistance.
Ventilation is managed by QVF three-position intake ducts and QVR exhaust ducts to promote effective airflow while riding. The side vent continues to function as an exhaust outlet even when the front shutter on the top duct is closed. FCS® cheek pads use a contoured shape, layered 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 help limit wind noise from below. The Peripherally Belted Super Complex Laminate Construction (PB-SCLC) shell combines multiple materials and construction techniques for a balanced blend of performance and value. With its tailored round oval fit, refined ventilation, secure shield system, and included Pinlock lens, the Arai Quantum-X is designed for comfortable, focused road riding.
