Product Concept & Specifications
Arai (Japan)Engineering & Biomechanical Safety Analysis
L'Arai Quantum-X Solid TC-5 est doté d'une coque avancée en PB-cLc pour une protection contre les impacts supérieure, tandis que sa forme de tête Round Oval garantit un ajustement confortable et sécurisé. Le casque intègre le système de ventilation avancé d'Arai avec de multiples entrées et sorties d'air pour un flux d'air optimal, gardant les motards au frais dans toutes les conditions. Conçu pour une protection intégrale, il comprend une doublure EPS multi-densité pour une sécurité accrue et un intérieur évacuant l'humidité pour un confort prolongé. La gamme Quantum-X est réputée pour son équilibre entre légèreté, durabilité et caractéristiques de sécurité haute performance.
The Arai Quantum-X Solid TC-5 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 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 Round 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.
