Engineering & Technical Analysis

Der Leatt MTB 4.0 V21 nutzt ein Dual-Density-EPS-Innensystem, das entwickelt wurde, um hohe Aufprallenergie zu absorbieren und gleichzeitig einen tiefen Schwerpunkt für optimale Fahrstabilität zu gewährleisten. Sein aerodynamisches Schalenprofil reduziert Windturbulenzen, was zu einem Luftwiderstandsbeiwert von 0,34 und einer effektiven akustischen Dämpfung führt, die den Geräuschpegel im Vergleich zu herkömmlichen Integralhelmen um etwa 4 dB senkt.
