The Arai Helmets Signet-X motorcycle helmet in Diamond Black and Medium is designed for riders who need a long-oval fit, with additional interior space from front to back and a narrower profile from side to side. This shape accommodates riders with a narrow head and a more pronounced forehead. Manufactured by Arai Helmets, the Signet-X combines a performance-focused shell, secure shield operation, effective ventilation, and a comfort-oriented interior for street and touring use. The manufacturer part number and vendor part number are both 0101-17719.
The Variable Axis System (VAS) shield mechanism helps optimize the shell shape while lowering the shield pivot point by an average of 24 millimeters. This creates a smoother shell surface in the critical temple area, helping the helmet manage impact energy more effectively. The VAS latch securely holds the shield closed and uses a larger design for intuitive operation. The included VAS-Max Vision shield accepts the VAS-MV Pinlock lens, and a Pinlock 120 lens is included to help reduce fogging in changing riding conditions.
Arai’s Peripherally Belted Super Complex Laminate Construction shell combines multiple materials and construction techniques for a balance of strength, performance, and value. QVF three-position intake and QVR exhaust ducts support airflow during rides, including continued side exhaust performance when the top vent shutter is closed. FCS cheek pads use contoured shaping, layered foam densities, and a foam spring to cradle the face, improve comfort, and help reduce wind noise. The removable, water-repellent ES chin cover enhances the helmet’s aerodynamic profile while increasing mouth-area exhaust. An odor-resistant liner helps resist bacterial buildup and keeps the interior fresher over extended use. This medium Signet-X is intended for riders whose head shape matches Arai’s long-oval fit profile.
