Design Concept & Background
"Safety First"
Le casque HJC i90 Modulaire est conçu pour le pilote moderne, alliant un style élégant à une fonctionnalité optimale. Sa conception avancée intègre un coque en polycarbonate léger, conçu pour offrir une protection maximale tout en minimisant le poids. L'aérodynamique joue un rôle essentiel dans la réduction du bruit du vent et des turbulences, garantissant une conduite plus fluide. Les canaux de ventilation efficaces maintiennent le pilote au frais, même lors d'une utilisation prolongée. La forme intermédiaire ovale de la tête du HJC i90 assure un ajustement confortable pour la majorité des pilotes, tandis que sa coque AIM+ avancée offre une protection supérieure aux impacts. Avec son design modulaire et ses caractéristiques de sécurité avancées, le HJC i90 est le choix idéal pour les pilotes à la recherche d'un équilibre entre style, performance et protection.

Product Concept & Specifications
HJC (South Korea)Engineering & Biomechanical Safety Analysis
Le HJC i90 est doté d'un coque en polycarbonate pour une durabilité légère et une sécurité avancée. Son design modulaire offre de la polyvalence, tandis que sa forme intermédiaire ovale de la tête assure un ajustement confortable pour la majorité des pilotes. Le casque comprend des canaux de ventilation efficaces pour maintenir le pilote au frais, et son rembourrage intérieur est conçu pour la respirabilité et le séchage rapide de l'humidité lors des longues distances.
The HJC i90 is engineered as a high-integrity Modular protective system, utilizing a structural shell constructed from Polycarbonate. 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 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.
