The 6D ATR-2 is the most advanced energy management device ever manufactured for off-road motorcycle competition or recreational riding. Infused with the exceptional DNA of the original ODS technology, but evolved to a whole new level with high-tech materials and design influenced by 6D's work inside the NFL’s Head Health Challenge III competition.
The inner EPS liner of any helmet is the first layer of defense and a very important component of the advanced ODS design of the ATR-2. It is effectively a helmet within a helmet. It has its own in-molded PVC (Polyvinyl Chloride) shell that serves many functions. It nests into the ODS carrier, provides strength and integrity to the EPS, and serves as a slippery surface to aide in reducing angular acceleration forces. The EPS is of a softer density than the EPP and is secured into the helmet with 4 locking pins that mate to the ODS carrier. It is also captured by the Chin Bar EPP which provides additional security.
