Verified Safety Snapshot
How this helmet’s verified certifications map to recognized safety homologations and crash testing.
Safety standards compliance is based on official manufacturer documentation and public safety laboratory test results. Always verify regional compliance labels on the physical helmet prior to use.
Verified Fit & Sizing Guide
Head shape profile matching and interactive size calculator based on verified manufacturer dimensions.
Conçu pour les formes de tête ovales à intermédiaires ; présente un processus de moulage de coque unique qui peut nécessiter des ajustements de taille spécifiques par rapport aux modèles Arai traditionnels.
How to measure
Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, and repeat for consistency.
Design Concept & Background
"Safety is our business"
Découvrez l'Arai Quantum-X : l'alliance du savoir-faire japonais 🇯🇵 et du mécanisme de visière VAS (Variable Axis System) avec verrouillage double, ainsi que des entrées d'air IC Duct 5. Il est doté d'une coque EPS multicouche à densité variable et d'une doublure intérieure amovible Dry-Cool antimicrobienne Eco-Pure. Idéal pour les motards exigeant une sécurité absolue et un confort aéro-acoustique optimal.

Product Concept & Specifications
Arai (Japan)Engineering & Biomechanical Safety Analysis
Équipé d'une construction en stratifié complexe (CLC) avec renfort de ceinture périphérique PB-SNC2 et une géométrie de coque lisse R75 pour la redirection de l'énergie d'impact par déviation. Il intègre le mécanisme de visière VAS (Variable Axis System) avec verrouillage double et des entrées d'air IC Duct 5. L'intérieur utilise une coque EPS multicouche à densité variable avec une doublure intérieure amovible Dry-Cool antimicrobienne Eco-Pure, comprenant des découpes préformées pour les haut-parleurs afin d'intégrer parfaitement les systèmes de communication Bluetooth.
The Quantum-X is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from PB-cLc. This structural layup is engineered to provide progressive kinetic energy dissipation during impact deceleration, distributing localized shock across outer lamina layers while minimizing deformation transfer into the internal multi-density EPS liner.
Certified to ECE 22.05, DOT, Snell M2020 protocols, the architecture is subjected to rigorous linear deceleration limits and oblique impact evaluations to mitigate rotational acceleration forces associated with diffuse axonal injury. For a deeper breakdown of rotational thresholds and impact testing speeds, consult our ECE 22.06 vs DOT vs SNELL engineering benchmark.
Internal geometry follows a Intermediate Oval cranial profile, designed to mitigate focal pressure hot spots across the parietal ridges while maintaining uniform radial clamping pressure along the zygomatic arch. Riders seeking optimal retention stability and break-in guidance should review the cranial aspect ratios and head shape guide as well as our 3D cheek pad density protocol.
Shell composite integrity and acoustic sealing are further optimized through channelized EPS porting and aerodynamic laminar profiling. To learn how shell composites resist stress cracking under prolonged environmental cycling, inspect the composite material comparative matrix.
