Design Concept & Background
"Lightweight Japanese Precision"
Dominez la route avec style grâce au Marushin Speedster Black, une pièce maîtresse de l'esthétique moderne pour la conduite en ville. Ce casque ouvert marie magistralement des lignes agressives et nettes à une finition noir mat élégante qui impose sa présence sans compromis sur la sécurité. Conçu aussi bien pour les trajets urbains quotidiens que pour les sorties cruiser du week-end, il offre une efficacité de ventilation supérieure pour vous garder au frais lors des longs trajets, tout en conservant un profil aérodynamique qui fend le vent. Sa forme ovale intermédiaire assure un maintien sûr et confortable sur la tête, vous permettant de vous concentrer pleinement sur la route. Avec sa construction robuste et son design intemporel, le Speedster n'est pas seulement un équipement ; c'est une extension essentielle de votre identité de motard.

Product Concept & Specifications
Marushin (Japan)Engineering & Biomechanical Safety Analysis
Le Marushin Speedster utilise une coque en polycarbonate léger renforcée par des nervures de contrainte internes en ABS pour maximiser la résistance aux impacts tout en minimisant la masse rotationnelle. Sa conception ouverte intègre un mécanisme d'écran solaire qui réduit les turbulences aérodynamiques, équilibrant l'isolation acoustique avec la liberté d'un champ de vision dégagé.
The Marushin Speedster Black is engineered as a high-integrity Open Face 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 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.
