The Arai Quantum-X Helmet combines refined comfort, advanced shield technology, and dependable ventilation for riders seeking a premium full-face helmet. This Diamond Black model in Small uses a round oval interior shape, with thicker front and rear pads and thinner side pads, to accommodate riders whose heads are slightly wider rather than elongated. The carefully shaped interior liner and supportive padding provide a secure, comfortable fit for everyday riding and extended time on the road. The Arai Quantum-X Helmet is identified by part number 0101-18170.
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 and supports more effective impact-energy management. The VAS latch securely captures the shield to help prevent unexpected opening, while its larger design makes shield operation intuitive. The included VAS-Max Vision shield accepts a Pinlock® lens, and a Pinlock® 120 MaxVision™ lens is included to help reduce fogging in changing riding conditions.
Ventilation is managed by QVF three-position intake ducts and QVR exhaust ducts for effective airflow 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 balanced air movement. FCS® cheek pads use contoured shapes, multiple foam densities, and a supportive 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 limit wind noise entering from below. The PB-SCLC shell combines multiple materials and construction techniques to deliver a strong, carefully engineered helmet platform.
