The 6D ATR-1 off-road motorcycle helmet, a true game changer that revolutionized the industry. It was the first helmet designed with a technology to reduce angular acceleration and low threshold impact energy transfer, thanks to the revolutionary Omni-Directional Suspension system. Today, the ATR-1 remains a top choice for safety and affordability. Experience the transformative power of the 6D ATR-1 and ride with confidence.

Product Adjustment: To minimize the impact of tariff classifications, new ATR-3 helmets, including those offered by FXR, will NO LONGER INCLUDE the deluxe helmet bag. It has been replaced with a premium, drawstring, helmet sock. Deluxe helmet bags will continue to be available for purchase separately. Fifth Generation ODS. Introducing Generation Five of 6D's Omni-Directional Suspension Technology. Their most advanced system to date, designed for today's extreme racing conditions. The enhanced system is more efficient, lighter, and freer to do its job, effectively mitigating energy transfer from crash impacts. Rebuildable. Like its predecessor, the ATR-3 takes head protection to the next level with its groundbreaking concept of rebuildability. Unlike traditional helmets, which are typically discarded after a significant impact, the ATR-3 is designed to be rebuilt and reused, continuing the legacy of innovation started by the ATR-2. Ram Air Direct-to-Brow Cooling. A new feature that enhances airflow and comfort. With newly designed direct channels and improved flow, this system efficiently directs cool air to the brow area and throughout the helmet, ensuring optimal ventilation and temperature regulation during use. 3K Carbon Composite Shell. The new shell material enables a 3K Carbon Fiber outer layer while maintaining 6D's renowned durability. The 6D 'Optimized Shell Design' concept uses multiple materials to enhance protection and energy management. The shell must prevent penetration without being overly stiff, as excessive stiffness impairs energy management. Multi-Impact Outer EPP Liner. The multi-impact EPP outer liner is strategically positioned against the helmet shell's inner surface. It is an exceptional energy absorption material designed with "Damping Towers" to provide a progressive spring rate to the suspended inner EPS liner during impacts. This capability, along with the EPP's multi-impact feature, is key in allowing the ATR-3 to be rebuilt. Replaceable Inner EPS Liner. The inner EPS liner is a crucial component of the ODS design, acting as the primary layer of defense. It functions as a helmet within a helmet. This inner liner nestles into the ODS carrier, offering strength and integrity to the EPS while reducing angular acceleration forces with its slippery surface. ODS 5 Isolation Dampers. Isolation Dampers connect the ODS carrier to the outer EPP liner, isolating impact forces from the brain. This new design features longer and more elastic dampers that require no gluing. Their unique shape provides progressive resistance to assist in managing the onset of angular acceleration, then subsequently returning the liner to its neutral position. Air-Gap Ventilation System with Ram Air Direct-to-Brow Cooling. A new feature that enhances airflow and comfort. With newly designed direct channels and improved flow, this system efficiently directs cool air to the brow area and throughout the helmet, ensuring optimal ventilation and temperature regulation during use. ODS Carrier. The new ODS carrier is lighter and simplified. It enables a modular helmet design that is easily rebuildable. It supports the isolation dampers, manages materials during impact, and recenters post-impact. EPP Chinbar. The EPP lined chinbar is thicker and has a lower density, offering increased durability and enhanced energy absorption for side impacts to the jaw area. It is equipped with a polyurethane over-molded sternum pad. Additional Safety Features. The new ATR-3 helmet incorporates several additional safety features. The chinbar has a clavicle cutout for more collarbone clearance, while the Cervical Protection Zone at the lower rear base provides extra crushable protection for the neck and spine in the event of downward and backward impacts. Additionally, shear-away visor screws enable the visor to break away during severe crashes.
