Product Concept & Specifications
Alpinestars (Italy)工学設計 & 技術分析
The Alpinestars SM5 represents a significant evolution in full-face helmet engineering, utilizing an advanced carbon fiber composite shell that drastically reduces weight without compromising structural integrity. The internal EPS liner is engineered with multi-density zones to optimize energy absorption during impact, adhering strictly to the latest ECE 22.06 safety standards which mandate higher retention force requirements than previous generations. Aerodynamic profiling has been meticulously tuned through wind tunnel testing, featuring a streamlined chin bar and rear spoiler integration that minimizes drag while maintaining high-velocity airflow through dedicated intake and exhaust ports.
