The Arai Quantum-X Helmet combines a refined round oval fit with advanced shell and shield technology for riders seeking dependable protection, comfort, and practical performance on the road. This Black Frost helmet features an interior liner with thicker front and rear pads and thinner side pads, creating a comfortable fit for riders whose heads are slightly wider rather than elongated. The Arai Quantum-X is designed with a clean, functional profile that supports long-distance riding and everyday use.
The Variable Axis System (VAS) shield system lowers the shield pivot point by an average of 24 mm, helping create a smoother shell surface in the critical temple area. This improved surface can help reduce the amount of impact energy transferred into the helmet. The VAS latch securely captures the shield to help prevent unexpected opening, while its larger design supports intuitive shield operation and integrates a convenient de-mist function. The included VAS-Max Vision (VAS-MV) shield accepts a VAS-MV 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, supporting effective airflow during changing riding conditions. The side vent continues functioning as an exhaust vent even when the front shutter on the top duct is closed. FCS cheek pads use contoured shapes, varying foam densities, and a supportive foam spring to cradle the face, improve comfort during 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 noise from below. The PB-SCLC shell combines multiple materials and construction techniques to deliver a balance of performance and value. Part number 0101-17660 identifies this Large Black Frost configuration.
