Engineering & Technical Analysis

The 6D ATR-2Y utilizes a proprietary carbon fiber composite layup optimized for motocross impacts, featuring a dual-density EPS liner that absorbs high-energy rotational forces. Its aerodynamic shell design incorporates active airflow channels that channel cooling air directly to the rider's neck and core, maintaining thermal regulation even at sustained racing speeds.
