Design Concept & Background
"Passion for Safety"
Découvrez l'équilibre parfait entre agilité urbaine et confiance à haute vitesse avec le Nolan N40-5. Ce casque jet premium redéfinit le style classique de la visière avec une aérodynamique moderne, arborant un design épuré et agressif qui impose sa présence sur toutes les routes. Conçu pour le motard exigeant qui refuse de faire de compromis sur la sécurité ou le confort, il offre une ventilation supérieure grâce à des entrées et sorties d'air stratégiquement placées, garantissant une circulation d'air frais même lors de sorties estivales intenses. Sa coque en polycarbonate légère réduit la fatigue cervicale, tandis que la calotte EPS avancée assure une protection sans compromis contre les impacts. Que vous naviguiez dans le trafic urbain ou que vous profitiez de la route, le N40-5 offre un mélange inégalé de style, de performance et de fiabilité.

Product Concept & Specifications
Nolan (Italy)Engineering & Biomechanical Safety Analysis
Le N40-5 utilise la construction de calotte EPS propriétaire de Nolan combinée à une coque en polycarbonate haute résistance pour répondre aux normes de sécurité ECE 22.06 tout en conservant une silhouette de casque jet. Son profil aérodynamique est optimisé par des tests en soufflerie, réduisant les flux d'air turbulents autour du menton et des joues pour minimiser la fatigue du pilote aux vitesses autoroutières.
The Nolan N40-5 is engineered as a high-integrity Open Face protective system, utilizing a structural shell constructed from Lexan. 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.
