Product Concept & Specifications
Alpinestars (Italy)Engineering & Biomechanical Safety Analysis
Die SM-5 Course nutzt Alpinestars' proprietäre Multi-Density EPS-Innenauskleidung und eine Verbundstoff-Schalenkonstruktion, um die Stoßabsorption zu maximieren und dabei ein leichtes Profil beizubehalten. Die aerodynamische Formgebung ist speziell auf Motocross abgestimmt und verfügt über eine flachere Visierform sowie optimierte Luftkanäle, die den Luftwiderstand reduzieren, ohne die Kühleffizienz bei hochintensivem Fahren zu beeinträchtigen.
The Alpinestars SM5 Course Blau is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from Polymer. 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 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.
