Design Concept & Background
"Protect what you love"
Beherrsche Straßen und Trails mit dem Leatt Velocity 4.0, einem Integralhelm, der für diejenigen konzipiert ist, die unnachgiebigen Stil und Sicherheit verlangen. Dieses leichte Meisterwerk vereint ein schlankes, aerodynamisches Design mit hochwertigen Belüftungskanälen, die dich bei hohen Geschwindigkeiten oder intensiven Stadtfahrten kühl halten. Hergestellt aus robusten Verbundmaterialien bietet es außergewöhnlichen Aufprallschutz ohne das Gewicht eines Vollvisierhelms und sorgt so für maximale Sicht und peripheres Bewusstsein. Das Innenfutter ist mit feuchtigkeitsableitender Technologie für ganztägigen Komfort ausgestattet, während das verstellbare Rückhaltesystem bei jedem Gasgeben einen sicheren, individuellen Sitz garantiert. Ob du durch den Stadtverkehr schlängelst oder abenteuerliche Nebenstraßen erkundest – der Velocity 4.0 liefert ein selbstbewusstes Fahrgefühl, das sich genauso gut anfühlt wie es aussieht.

Product Concept & Specifications
Leatt (New Zealand)Engineering & Biomechanical Safety Analysis
Die Leatt Velocity 4.0 verwendet einen fortschrittlichen EPS-Innenschuh mit Zonen variabler Dichte, um die Aufprallenergie über den gesamten Schädel hinweg optimal zu absorbieren. Ihre Open-Face-Architektur zeichnet sich durch ein stromlinienförmiges Schalendesign aus, das den frontalen Luftwiderstand minimiert und gleichzeitig durch eine Verbund-Fiberglas-Konstruktion strukturelle Steifigkeit gewährleistet.
The Leatt Velocity 4.0 is engineered as a high-integrity motorcycle protective system, utilizing a structural shell constructed from Polycarbonate. This structural layup is engineered to provide progressive kinetic energy dissipation during impact deceleration, distributing localized shock across outer lamina layers while minimizing deformation transfer into the internal multi-density EPS liner.
Certified to ECE 22.05, DOT protocols, the architecture is subjected to rigorous linear deceleration limits and oblique impact evaluations to mitigate rotational acceleration forces associated with diffuse axonal injury. For a deeper breakdown of rotational thresholds and impact testing speeds, consult our ECE 22.06 vs DOT vs SNELL engineering benchmark.
Internal geometry follows a Intermediate Oval cranial profile, designed to mitigate focal pressure hot spots across the parietal ridges while maintaining uniform radial clamping pressure along the zygomatic arch. Riders seeking optimal retention stability and break-in guidance should review the cranial aspect ratios and head shape guide as well as our 3D cheek pad density protocol.
Shell composite integrity and acoustic sealing are further optimized through channelized EPS porting and aerodynamic laminar profiling. To learn how shell composites resist stress cracking under prolonged environmental cycling, inspect the composite material comparative matrix.
