The Arai Helmets Contour-X Helmet in Proto Yellow, size Large, combines touring-focused comfort, ventilation, and aerodynamic stability with Arai’s renowned shell construction. Manufacturer part number 0101-20474 and vendor part number 0101-20474 identify this helmet for accurate ordering and fitment. Its outer shell uses Peripherally Belted Complex Laminate Construction (PB-cLc2) with an additional Super Fiber belt to provide lightweight strength, a smooth profile, and flat side areas that support convenient communication-system installation.
The 3D Arai logo duct is only 3.5 mm deep and feeds two central 10 mm intake ports. Its short-stroke lever is easy to operate with summer or winter gloves, while the duct’s position provides a quick visual indication of whether it is open or closed. A three-position sliding chin vent offers open, midway, and closed settings, delivers substantial airflow, and includes a replaceable filter. The rear aerodynamic spoiler uses a three-way switch for open, midway, and closed operation, drawing air through three shell ports while helping smooth airflow, reduce buffeting, and improve stability at highway speeds. The spoiler is designed to crush or break away during an impact without compromising protective performance.
Arai’s Variable Axis System (VAS) lowers the visor mounting position to support a smoother shell shape designed to improve glancing performance. The shell opening is flared for easier helmet removal, while a stitched opening inside the neck roll helps installers conceal excess communication-system wiring. The Contour-X is designed to accommodate an intercom system on the exterior of the shell without requiring changes to the protective inner EPS liner. This Large Proto Yellow model is suited for riders seeking a premium full-face touring helmet with adjustable ventilation, aerodynamic refinement, and communication-system compatibility.
