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 Intermediate Oval head shape; offers a snug fit with minimal volume. Requires precise sizing as it runs small around the cheeks and temples.
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
6D (Italy)Engineering & Biomechanical Safety Analysis
El 6D ATR-2 utiliza una arquitectura de revestimiento EPS de densidad múltiple patentada y una avanzada carcasa de compuesto de fibra de carbono para lograr una absorción de impactos excepcional manteniendo un bajo coeficiente de resistencia. Su perfil acústico de cara abierta está diseñado para reducir el ruido del viento hasta en un 30% en comparación con los cascos de MX estándar, contando con un sellado de visor único que minimiza la turbulencia a altas velocidades.
The 6D ATR-2 Operator Grey is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from Composite. 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.
