Design Concept & Background
"Safety First"
L'HJC RPHA 71 incarne le sommet de la conception de casque de tourisme, où un style élégant rencontre une ingénierie avancée. Sa forme aérodynamique coupe le vent avec facilité, tandis que le système de ventilation arrière à 360° (RRV) assure un flux d'air optimal et une régulation de la température lors des longs trajets. La coque PIM Evo offre une résistance aux chocs et une durabilité légères inégalées, protégeant la tête du pilote avec une protection rassurante. Un intérieur asséché et rembourrage réglable garantissent un ajustement confortable, tandis que le système de ventilation avancé maintient la vision du pilote dégagée et claire. Avec sa certification DOT et ECE 22.06, l'HJC RPHA 71 établit de nouvelles normes en matière de sécurité et de performance. Que vous naviguiez sur des routes sinueuses ou que vous roulez sur l'autoroute, ce casque est le compagnon idéal pour les cavaliers exigeants.

Product Concept & Specifications
HJC (South Korea)Engineering & Biomechanical Safety Analysis
L'HJC RPHA 71 présente une sécurité avancée grâce à sa coque PIM Evo, offrant une durabilité légère et une résistance supérieure aux chocs. Le confort est amélioré par un intérieur asséché et rembourrage réglable, tandis que le système de ventilation avancé assure un flux d'air optimal grâce à plusieurs entrées et sorties d'air pour une régulation de la température lors des longs trajets.
The HJC RPHA 71 is engineered as a high-integrity Touring protective system, utilizing a structural shell constructed from PIM Evo. 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 22.06, 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.
