Product Concept & Specifications
Nexx (Portugal)Engineering & Technical Analysis
Die Nexx X.404 verwendet ein Mehrdichtepolster von EPS, das darauf ausgelegt ist, hohe Energie bei hohen Aufprallkräften aufzunehmen, während es ein leichtes Profil beibehält, das für offene Gesichtsdesigns unerlässlich ist. Sein aerodynamischer Helm besitzt integrierte Windabweiser, die den Luftstrom über dem Gesicht des Fahrers leiten, wodurch die Turbulenzen und das Lärmen gegenüber Standard-Offen-Gesichtsdesigns erheblich reduziert werden.
