Product Concept & Specifications
Arai (Japan)Engineering & Biomechanical Safety Analysis
Ausgestattet mit Complex Laminate Construction (CLC) inklusive PB-SNC2 peripherer Gürtelverstärkung und einer R75 glatten Schalengeometrie zur Ablenkung von Aufprallenergien. Kombiniert mit dem VAS (Variable Axis System) Visiermechanismus mit Doppel-Vierfach-Visierverriegelung und IC Duct 5 Belüftungsöffnungen. Das Innenleben nutzt einen einteiligen EPS-Innenausbau mit Mehrdichte und ein abnehmbares Dry-Cool Innenfutter mit Eco-Pure antimikrobieller Beschichtung sowie vorgeformten Lautsprecheraussparungen für eine nahtlose Bluetooth-Kommunikationsintegration.
The Defiant-X is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from PB-cLc2. 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.
