Introducing the all new ATR-2; the next level in brain protection. 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.A helmet with in a helmet, the ATR-2 with advanced ODS is evolved to provide improved performance in both linear and angular acceleration mitigation, and is also easily rebuildable for a potentially longer service life. This improves rider safety and saves the consumer money.Rebuildable Advanced ODS System:- Replaceable inner EPS liner.- Multi-Impact outer EPP liner.- Progressive EPP Damping Towers.- Low-friction disks.- Isolation dampers.- Increased ODS Displacement Travel ( 30%).- Improved Linear and Angular acceleration mitigation.Shell:- Optimized light weight Tri-Composite Shell.- Cervical protection zone at the lower rear shell area.- Brow rib increases shell integrity above the eyeport.- Clavicle cut-away.- 9 intake ports and 6 exhaust ports work in unison with the Air Gap Ventilation System.Helmet Features:- Removable, washable comfort liner features Genuine Dri-Lex anti-bacterial fabric.- Emergency Quick-Release Cheek Pads.- PU-over molded EPP lined chin bar includes 6D's exclusive sternum pad.- Goggle band integrated shell recess at the eyeport area improves goggle fit and seal.- Shear-away visor screws.- Nose guard provides improved roost protection.- Titanium D-rings.- Lighter overall weight.- Exceeds DOT, ECE, AC and ASTM standards.- 3-year limited warranty.
