• Description

  Known for handcrafting the best helmets in the world, the Arai Quantum-X helmet is no exception. Boasting an all-new Peripherally Belted - Super Complex Laminate Construction (PB-ScLc) shell design delivers both performance and affordability while incorporating the elegant new Variable Axis System (VAS) shield that allows a rounder shell shape and an easy-to-use changing system. The Quantum-X comes standard with a VAS Max Vision faceshield to provide better visibility 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.

  The Quantum-X has Arai's Round Oval (RO) interior fit shape. Shorter front-to-back and a little wider side-to-side (as compared to Intermediate Oval).

  • VAS System:
  • The Variable Axis System shield mechanism was developed to enhance the shape of the shell, but the easy-to-learn changing mechanism is what most people are raving about. Quick, easy and intuitive.
  • PB-SCLC:
  • The new Peripherally Belted - Super Complex Laminate Construction shell design combines multiple materials and techniques created internally by Arai that deliver both performance and affordability.
  • Duct Ventilation:
  • In keeping with the "improve on what works" mentality at Arai, the new QVF and QVR upper ventilation ducts look familiar but offer more adjustment and better flow-through performance.
  • Chincover:
  • The new water-repellent ES Chincover comes installed on the Quantum-X.
  • Enhancing the egg shape of the helmet, the cover smooths airflow, increases exhaust from the mouth area and reduces wind noise coming up from below.
  • Good for both cold and warm weather riding and is easy to remove and reinstall as needed.
  • Liner:
  • The liner material on the Quantum-X allows your helmet to stay fresher, longer, between cleanings.
  • VAS-MV Pinlock Anti-Fog Lens:
  • The Quantum-X comes with the VAS-MV (Max Vision) shield that accepts the new VAS-MV Pinlock lens.
  • The new Pinlock-120 lens comes with the helmet in the box and ready to install.
  • Compatible with the VAS-V Pro Shade system (sold separately).
  • DOT and SNELLM2020 certified.

  Note: Fluorescent and/or bright finishes fade over time and exposure to sunlight. This is normal and is not covered by warranty.
