Design Concept & Background
"Safety First"
Tipo: Capacete integral | Marca: Steelbird
O Sba 21 Gt Preto Mate Lg foi desenvolvido pela Steelbird como um sistema de proteção de alta integridade do tipo capacete integral, utilizando um casco estrutural fabricado em casco multi-compósito com revestimento em EPS. Essa estratificação de compósitos garante uma dissipação progressiva da energia cinética de impacto, distribuindo os picos de pressão nas camadas exteriores e limitando a deformação sobre o EPS interno multidensidade.
Homologado pelos padrões ECE 22.06 / DOT, o capacete atende a rigorosos limites de desaceleração linear e impactos oblíquos para mitigar acelerações rotacionais. Para detalhes sobre ensaios mecânicos e limiares de segurança, consulte nosso guia sobre os padrões de segurança de capacetes ECE 22.06 vs DOT vs SNELL.
A ergonomia interna baseia-se no formato craniano Oval Intermediário (Intermediate Oval), desenhado para eliminar pontos de pressão nas cristas parietais mantendo contato uniforme ao longo do arco zigomático. Para orientações sobre estabilidade e amaciamento, confira nosso guia de proporções anatômicas e formatos de cabeça e o protocolo de ajuste e assentamento das bochecheiras.
A acústica de cabine e os fluxos aerodinâmicos registram um nível de ruído em torno de 84.0 dB a 100 km/h, estabilizado por condutos internos no EPS e perfil externo laminar. Conheça a resistência mecânica das fibras perante intempéries e raios UV em nosso comparativo de materiais: fibra de carbono, fibra de vidro e policarbonato.
Sinergia com o veículo e modalidade de pilotagem: Afinado para sustentação neutra e captação eficiente de ar frontal, este capacete é ideal para pilotagem esportiva e viagens prolongadas. Com peso de 1200 gramas, proporciona centro de gravidade equilibrado, reduzindo a fadiga cervical. Consulte nosso diretório de compatibilidade com motocicletas para combinações ideais de postura e para-brisa.

Product Concept & Specifications
Steelbird (India)Engineering & Biomechanical Safety Analysis
The Sba 21 Gt Preto Mate Lg is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from High-impact 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 ISI IS 4151 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.
