Quick Facts at a Glance
Verified Safety Snapshot
How this helmet’s verified certifications map to recognized safety homologations and crash testing.
Safety standards compliance is based on official manufacturer documentation and public safety laboratory test results. Always verify regional compliance labels on the physical helmet prior to use.
Verified Fit & Sizing Guide
Head shape profile matching and interactive size calculator based on verified manufacturer dimensions.
Designed for oval to intermediate head shapes; may feel tight on very round heads due to aggressive cheek pad design.
How to measure
Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, and repeat for consistency.

Product Concept & Specifications
LS2 (Spain)Engineering & Biomechanical Safety Analysis
El LS2 Stream 2 Vortex utiliza un forro EPS de doble densidad y un sistema de retención extendido para garantizar una sujeción precisa de la cabeza durante maniobras de alta fuerza G. Su diseño de carcasa aerodinámica minimiza la turbulencia en la mentonera, mientras que el mecanismo de visor integrado reduce las vibraciones por viento, equilibrando la rigidez estructural con una construcción ligera.
The LS2 Stream 2 涡流红 is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from KPA. 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 DOT, ECE 22.06 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.
