The Arai Quantum-X Helmet in Aluminum Silver is designed for riders who need a comfortable round oval fit and dependable performance on the road. Part Number 0101-18165 features an interior head liner with thicker front and rear pads and thinner side pads, creating a shape suited to heads that are slightly wider rather than elongated. The carefully contoured interior supports a secure, comfortable fit for everyday riding and extended journeys.
The Variable Axis System (VAS) shield system lowers the shield pivot point by an average of 24 mm, creating a smoother shell surface through the critical temple area. This design helps improve the helmet’s ability to glance off impacts while supporting Arai’s focus on shell integrity. The improved VAS latch captures and securely holds the shield closed to help prevent unexpected opening. Its larger design also supports intuitive shield operation and integrates a convenient de-mist function. The helmet includes a VAS-Max Vision shield that accepts a VAS-MV Pinlock lens, with a Pinlock 120 MaxVision lens included.
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 vent even when the front shutter on the top duct is closed. FCS cheek pads use contoured shapes, multiple foam densities, and a supportive foam spring to cradle the face, improve comfort during installation and removal, and help reduce wind noise. A water-repellent ES chin cover is installed to enhance the helmet’s egg-shaped profile, smooth airflow, increase exhaust from the mouth area, and reduce wind entering from below. The PB-SCLC shell combines multiple materials and construction techniques for balanced performance and value.
