Design Concept & Background

"Safety First"

Beherrsche die Straße mit dem Steelbird Rocket Silver, einem Meisterwerk des italienisch inspirierten Designs, vereint mit unnachgiebiger Sicherheitstechnik. Dieser Jethelm überzeugt durch eine aggressive, aerodynamische Silhouette, die den Wind durchschneidet und gleichzeitig für hervorragende Belüftung sorgt, um dich auch auf langen Touren kühl zu halten. Die hochglänzende silberne Oberfläche strahlt premium Style aus und macht ihn zur herausstechenden Wahl für Stadtpendler und Rennstrecken-Enthusiasten, die Sichtbarkeit ohne Kompromisse bei Schutz verlangen. Innen sorgt der individuell geformte Schaum für einen passgenauen, sicheren Sitz, der Ablenkungen eliminiert und dich vollständig auf die Straße vor dir konzentrieren lässt. Mit seiner robusten Verarbeitung und schlanken Ästhetik ist der Rocket Silver nicht nur Schutzausrüstung – er ist eine Erklärung von Leistung und Freiheit.

Product Concept & Specifications

Steelbird (India)

Engineering & Biomechanical Safety Analysis

Steelbird Rocket nutzt eine verstärkte Polycarbonat-Schale mit integrierter EPS-Innenauskleidung, die den ECE 22.06-Sicherheitsstandards entspricht und dabei ein leichtes Profil beibehält. Das Integralhelm-Design verfügt über einen strömungsoptimierten Kinnbügel und optimierte Luftkanäle, die thermische Regulierung mit minimalem Luftwiderstand ausbalancieren und so Stabilität bei hohen Geschwindigkeiten gewährleisten, ohne den akustischen Komfort zu beeinträchtigen.

The Steelbird Rocket Silver is engineered as a high-integrity Open Face protective system, utilizing a structural shell constructed from ABS. 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 DOT, ISI 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.
