The Arai Quantum-X Helmet in Diamond Black, Medium, is designed for riders who prefer a slightly wider, round-oval head shape rather than an elongated fit. Its interior head liner uses thicker front and rear pads with thinner side pads to provide a secure, comfortable fit for the intended head profile. Manufactured by Arai Helmets, this helmet carries manufacturer and vendor part number 0101-18171.
Its PB-SCLC shell construction combines multiple materials and techniques to provide a strong, carefully engineered shell design. The Variable Axis System (VAS) shield system lowers the shield pivot point by an average of 24 mm, helping create a smoother shell surface around the temple area for improved glance-off performance. The VAS shield latch securely holds the shield closed and features a larger design for intuitive operation, including easier use of the de-mist function.
Ventilation is managed by QVF three-position intake and QVR exhaust ducts to promote efficient airflow while riding. The side vent continues functioning as an exhaust outlet even when the front shutter on the top duct is closed. FCS cheek pads use contoured shapes, multiple foam densities, and a foam spring to cradle the face, simplify helmet removal, and help reduce wind noise. A water-repellent ES chin cover is installed to enhance the helmet’s egg-shaped profile, smooth airflow, improve mouth-area exhaust, and limit wind noise from below.
The Arai Quantum-X includes a VAS-Max Vision (VAS-MV) shield that accepts a Pinlock lens, along with a Pinlock 120 MaxVision lens for improved fog resistance. This Diamond Black Medium model is intended for compatible motorcycle riding applications and is supplied as a complete helmet assembly. Brand: Arai Helmets. Manufacturer part number: 0101-18171.
