Perfect for standard intermediate head profiles.

Aggressive fit with high cheek pads; designed for MX riders requiring a locked-in position; runs slightly small compared to standard DOT helmets due to the internal suspension geometry.

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."

Dominate the track with the 6D ATR-2 Hi-Viz Yellow, a pinnacle of motocross engineering designed for riders who demand uncompromising safety and superior comfort. This helmet features an advanced aerodynamic profile that slashes wind resistance by 15% while its revolutionary acoustic technology dampens roaring engine noise to levels comparable to street riding. The high-visibility yellow shell isn't just a style statement; it ensures maximum rider visibility in low-light conditions, enhancing safety without sacrificing aggressive aesthetics. Inside, the custom-fit liner molds to your head for a glove-like embrace, preventing pressure points during long motos. With an exceptional ventilation system that channels airflow directly to critical zones, you stay cool when the heat rises. Whether you are tackling technical dirt jumps or high-speed straights, the ATR-2 delivers the perfect blend of race-proven protection and modern performance technology.

Engineering & Biomechanical Safety Analysis

The ATR-2 utilizes a proprietary multi-density EPS liner architecture and an aerodynamic shell contour designed to minimize vortex shedding at high speeds. Its integrated acoustic dampening system significantly reduces wind noise compared to standard motocross shells, while the extensive venting network ensures thermal regulation during intense off-road sessions.

The 6D ATR-2 Giallo ad alta visibilità 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.
