Introducing the new ATR-2Y with advanced ODS. 6D changed the helmet industry forever in 2013 with the introduction of the revolutionary ATR-1 off-road motorcycle helmet with its patented Omni-Directional Suspension (ODS) technology. 6D's technology has been studied, analyzed, and tested by some of the greatest minds in head protection, and has proven itself effective all around the globe, and across multiple 6D helmet designs by now.
Introducing the all new ATR-2Y youth off-road competition helmet. Simply put, it's the next level in brain protection for the today's youngest moto athletes. The 6D ATR-2Y follows directly in its parent's footsteps. It is the most advanced helmet available for off-road motorcycle (or cycling) competition or recreational riding. Infused with the same advanced ODS technology as the adult ATR-2, the youth model was specifically designed for the needs of the growing child and their still-developing brain. Softer foam liners combined with a more aggressive and freer uncoupling carrier system, provide truly next level protection.
Advanced ODS: What's Different and Why Is It Better?
How Omni-Directional Suspension Works:
At the onset of any impact the ODS system's isolation dampers activate immediately addressing the forces applied to the helmet. The isolation dampers compress and shear in response to the impact thereby reducing the transfer of that force to the inner helmet, head form, and brain. If the force applied to the helmet is more extreme, the isolation dampers transition the energy management job to the two energy absorbing compressible liners which are designed to manage higher velocity impacts in a more traditional manner. This dual-liner system allows ODS to manage impact forces in a superior manner to the other competing technologies in the marketplace.
Recent medical research has provided alarming conclusions surrounding the causes, severity, and long-term effects of concussions. Even seemingly minor concussions may have much more serious long-term effects on the brain. Repetitive low-velocity impacts are cumulative apparently causing buildup of tau proteins and deterioration of the brain's healthy condition.
To meet the various mandatory global certification standards' high-velocity requirements, helmets incorporating add-in shear plane technologies such as MIPS to address rotational force are still way too stiff to effectively absorb energy from impacts at lower velocities.
With this well noted, the vast majority of impacts one might experience in real-world accidents qualify as low-threshold energy impacts; impacts well below certification standards pass / fail velocities, but severe enough to sustain a concussion or a traumatic brain injury (TBI).
ODS starts working the instant any force is applied to the shell, making the helmet more compliant and progressive over the broad range of impact velocities experienced in the highest percentage of 'real world' crashes, while still exceeding the requirements of the global standards.
The medical community has determined that angular acceleration (rotational force generated during oblique-angle impacts) is the primary cause of concussion and traumatic brain injury.
Traditional helmets are directly "coupled" to the head preventing any ability to mitigate angular acceleration forces. Scientific laboratory testing proved that when subjected to identical impacts, a helmeted head sustained the same degree of angular acceleration as an un-helmeted head (experiments conducted by David C. Viano, PhD, Bioengineering Center, Wayne State University.).
ODS technology "uncouples" the helmet from the head form. The suspended dual-liner assembly compresses and shears omni-directionally when subjected to oblique impacts thereby reducing the transfer of angular acceleration forces to the head and brain.
Competing technologies including MIPS, Flex, Turbo 360, LDL, Meds, Fluid Pod, etc. are all trying to uncouple the relationship of the head and the helmet. Each however, is challenged with the same issue; the natural oval shape of the human head. That shape restricts movement. While some of these technologies function better than others, none provide the well-rounded performance of Omni-Directional Suspension.
Broad Range Protection:
Across the entire range of potential impact velocities, the 6D ATR-2Y helmet with ODS technology consistently outperforms competitive designs. 6D extensively engineers the shell, liners, damper systems, and ODS to provide the best possible impact mitigation performance across all impact velocities for both angular and linear accelerations.
Time-to-Peak (TTP) is how long it takes the energy of an impact to reach maximum G-force. Deceleration time is the single most beneficial component in reducing the severity and magnitude of any impact - the more time, the less energy transferred. ODS buys time during the impact event!
Helmet Size and Volume:
Don't be fooled by marketing hype. Think about it...In a crash event the head form is coming to an instantaneous extreme stop. You want to have this happen over the most time and distance possible to reduce the severity of the deceleration on the brain. A small shelled helmet obviously compromises this as the head will bottom out on the shell (causing accelerations to skyrocket) unless the manufacturer utilized extra stiff EPS to manage the extreme impact force. So while you might get a similar maximum "G" figure at the certification test velocity as a larger shelled helmet, the stiff EPS is grossly ineffective at managing energy at the lower velocities of most crash events.
