Engineering & Biomechanical Safety Analysis

El GMax GM-11S Silver Metallic cuenta con una carcasa de policarbonato para una durabilidad ligera y resistencia a los impactos, ideal para el uso en tierra y MX. Su forma de cabeza ovalada intermedia garantiza un ajuste seguro, mientras que el sistema de ventilación del casco promueve el flujo de aire para mantener a los pilotos frescos. El diseño prioriza la comodidad con un acolchado interior que absorbe la humedad, haciéndolo adecuado para un uso prolongado fuera de carretera. La seguridad se ve reforzada con un forro EPS de densidad múltiple para la absorción de energía durante los impactos.

The GMax GM-11S Argento metallizzato is engineered as a high-integrity Dirt/MX 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 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.
