Known for their reputation for handcrafting the best helmets in the world, the Arai Quantum-X helmet is no exception. Boasting a PB-ScLc (Peripherally Belted - Super Complex Laminate Construction) shell design delivers both performance and affordability while incorporating the elegant VAS (Variable Access System) shield that provides a rounder shell shape and an easy to use changing system. The Quantum-X comes standard with the VAS Max Vision faceshield to provide better visibilty in all seasons and for all types of riding. The VAS shield is smaller and lower than the previous design with adjustable air intake vents that provide improved sealing, which decreases road noise and water intrusion.


  • Peripheral Belted Super Complex Laminate construction shell design combines multiple materials and techniques created by Arai to deliver both performance and affordability
  • Features Variable Axis System shield mechanism developed to enhance the shape of the shell, but the easy to learn changing mechanism is what most people are raving about
  • Round oval head shape
  • QVF and QVR upper ventilation ducts offer more adjustment and better flow through performance
  • Water repellent ES chin cover comes installed, enhancing the egg shape of the helmet

  • Antimicrobial liner material resists the build up of bacteria and as a result allows your helmet to stay fresher, longer, between cleaning
  • VAS-MV Pinlock anti-fog lens
  • Pinlock-120 lens included in box ready to install
  • Meets or exceeds DOT and Snell M2015 standards
  • Black/Multi

General Sizing Information

If you are unsure about your size, compare your body measurements to the charts provided to determine the correct fit. These charts will give you a good idea of the size to order, but be sure to read special sizing information that may accompany an item description. Some merchandise dimensions may vary from the averages charted here.

Head Circumference

Head circumference measurements should be a starting point only in determining your helmet size. Determining the best possible fit should be from actual test fittings of Arai's various interior fit packages, with optional interior lining and cheek pad thicknesses to find the best fit.

Interior Liners and Cheek Pads

Optional interior liners and cheek pads of different thicknesses allow you to custom fit your Arai helmet. When ordering a liner of a different thickness, start with the Lining Code that matches your helmet size, then specify the desired thickness. For example, an optional 5 mm liner for a large helmet would be specified as a "III - 5 mm" liner.
