Engineering & Technical Analysis

Die SM5 nutzt Alpinestars’ proprietäres Multi-Directional Impact Protection System (MIPS), um Rotationskräfte bei Hochgeschwindigkeitsaufprallen zu reduzieren. Ihr aerodynamisches Schalen-Design zeichnet sich durch eine flachere Visierform und optimierte Kinnbügelgeometrie aus, die Windturbulenzen verringert und gleichzeitig ein offenes akustisches Profil für Motocross-Umgebungen beibehält.
