Arai Quantum-X Solid Helmets

Known for their reputation 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 Access System (VAS) shield that provides 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.
