Engineering & Technical Analysis

Die Alpinestars S-M5 Action nutzt eine mehrschichtige EPS-Innenschale und ein fortschrittliches Rückhaltesystem, um eine präzise Kopfhaltung bei aggressiven Motocross-Manövern zu gewährleisten. Das aerodynamische Schalen-Design reduziert Luftturbulenzen, während die integrierte Sonnenblende und der akustische Schaum hochfrequente Geräusche gezielt dämpfen, ohne die Atmungsaktivität zu beeinträchtigen.
