Arai Helmets Quantum-X Diamond Black Helmet - Medium (Part Number 0101-18171)

The Arai Helmets Quantum-X Helmet in Diamond Black is designed for riders seeking optimal comfort and advanced safety features. Its round oval shape, achieved through an interior headliner with thicker front and rear pads combined with thinner side pads, offers a better fit for riders with wider heads, ensuring comfort during long rides. The helmet's shell utilizes Peripherally Belted - Super Complex Laminate Construction (PB-SCLC), integrating multiple materials to provide durability, performance, and affordability. Weighing approximately 73.6 ounces, this helmet balances lightweight comfort with robust protection.
Enhanced impact mitigation is achieved through the Variable Axis System (VAS) shield system, which lowers the pivot point by an average of 24 mm, creating a smoother surface in the temple area to reduce impact energy transfer. The VAS latch securely holds the shield closed, preventing accidental openings while allowing intuitive operation, complemented by a de-mist function for clear visibility. The Quantum-X features QVF three-position intake and QVR exhaust ducts, ensuring excellent airflow management for comfort and fog prevention. The side vent continues to function as an exhaust even when the top shutter is closed, maintaining consistent ventilation.
The helmet incorporates FCS® Cheek Pads, which are contoured and layered with varying foam densities supported by a foam “spring,” cradling the face comfortably while blocking wind noise and facilitating easy on/off. The water-repellent ES chin cover enhances the helmet's aerodynamic profile, improves airflow, and reduces wind noise from below. The VAS-Max Vision (VAS-MV) shield accepts the VAS-MV Pinlock® lens, with a Pinlock® 120 MaxVision™ insert included, providing fog resistance and clear vision during rides. This helmet combines advanced safety features with thoughtful design elements to meet the demands of serious riders seeking quality, comfort, and protection on every journey.
