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.
Aggressive fit with high cheek pads; runs slightly small for those preferring a loose street helmet feel. Requires precise sizing as the shell is designed to move with the head during impacts. Optimized for Intermediate Oval head shapes.
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.
Design Concept & Background
"Perfect Fit. Perfect Protection."
Domina cualquier terreno con el 6D ATR-2Y Matte Black, un casco diseñado para el piloto de motocross y enduro moderno que exige una protección sin concesiones sin sacrificar el estilo. Este casco premium para motos de cross cuenta con la tecnología de forro EPS de densidad múltiple característica de 6D, que garantiza una absorción de impactos superior adaptada a la forma de tu cabeza. El agresivo acabado en negro mate emana autoridad, mientras que el avanzado perfil aerodinámico corta el aire a altas velocidades, reduciendo la resistencia y el ruido del viento. Experimenta una refrigeración mejorada con un sofisticado sistema de ventilación que introduce activamente aire fresco y expulsa el aire caliente, manteniéndote concentrado durante trayectos largos. Equipado con un sistema de retención seguro y una carcasa de policarbonato resistente a los arañazos, el ATR-2Y no es solo equipo de seguridad; es una declaración de rendimiento. Ya sea que estés compitiendo en la pista o explorando senderos remotos, este casco te brinda la confianza para superar tus límites de forma segura.

Product Concept & Specifications
6D (Italy)Engineering & Biomechanical Safety Analysis
El ATR-2Y utiliza un forro EPS de densidad múltiple diseñado específicamente para la forma de cabeza Oval Intermedia para una distribución óptima del impacto. El diseño de su carcasa aerodinámica cuenta con conductos de aire integrados que canalizan el aire de impacto directamente hacia la cara y el cuello del piloto, reduciendo significativamente la acumulación térmica en comparación con los diseños off-road tradicionales.
The 6D ATR-2Y Matte Black is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from Carbon-Kevlar. 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.
