6D - ATR-1 Shear Helmet
A True Game Changer. The 6D ATR-1 off-road motorcycle helmet has changed the industry forever. Introduced in 2013 it was the first motorcycle helmet ever manufactured incorporating technology that reduced angular acceleration and low-threshold impact energy transfer to the brain during crash impact. This was accomplished by 6D’s revolutionary Omni-Directional Suspension (ODS) system.
The 6D ATR-1 was the “Game Changer” in 2013, and today it is still the most effective off-road helmet available for athletes looking for the ultimate in head protection. The ATR-1 is certified to exceed US DOT FMVSS 218 and ASTM F3103 (US), ECE 22.05 (47 Countries World-Wide), AS 1698 (Australia) and ACU (UK) standards.

Sizing your head for the proper motocross helmet size is important. Using a soft tape measure, wrap it around your head at the largest point starting about 1” (2.5cm) up from your eyebrows and around the largest part of the back of your head, and measure the number of your head circumference. Compare your size to the chart below.
