6D Helmets





6D’s revolutionary patent pending ODS™ (Omni-Directional Suspension™) represents a fully active, in-helmet suspension and kinetic energy management  system. The mechanics, engineering, materials, and manufacturing are very complicated, but actually, the concept is quite simple.

Working with leading research and development experts in the area of motorcycle helmet safety, design, and advanced product testing, our goal was simple; design a better performing off-road motorcycle helmet. We applied creative ‘clean-sheet’ engineering concepts to the problem and started building prototype helmets for testing. Extensive testing provided data to support a vastly superior ‘proof of concept’ design. This design matrix was taken into beta testing for further evaluation and development, and then on to pre-production testing.

To manage kinetic energy (including linear, angular, and lower-threshold acceleration energy), the ODS™ system starts with an internal EPS liner not unlike traditional helmets; but that is where the similarities end. With the ODS™ system, the EPS liner is divided, creating a compound-liner assembly. These two liners are separated by a very specific programmed array of elastomeric isolation dampers creating an air-gap. It is this array of isolation dampers surrounding the entire liner, combined with the air-gap, that affords the free-motion suspension capability of ODS.™

The unique ‘hourglass’ shape designed into the elastomeric isolation dampers function with specially designed frusto-conical ramping chambers within the ODS™ system to produce a rapidly escalating spring rate under compressive load. These same features allow the split liner system to shear omni-directionally within itself to provide improved performance against oblique impacts and angular acceleration demands. There is no other helmet technology that can offer these combined energy management features.

6D’s™ innovative ODS™ system improves impact force management within the helmet’s interior environment. Omni-Directional Suspension™ (ODS™) technology is designed to protect your head over a broader range of energy transfer; especially angular energy in low and high velocity impacts, than traditional helmet designs. In testing, ODS™ has shown to significantly reduce the energy transferred to the head. This can reduce the likelihood of a concussion or brain injury over a traditional helmet.



Angular Accelleration

Experiments conducted by David C. Viano, PhD. M.D. and the Bioengineering Center at Wayne State University confirmed that a helmeted head sustained the same degree of angular acceleration as the un-helmeted head when subjected to identical impacts. So, if angular acceleration is the major cause of brain injury, then how is the brain protected by traditional helmet technology? Unfortunately, in the aspect of angular acceleration, it is not.

The focal point of traditional helmet design has always been directed at providing protection against linear impact energy test compliance. Helmets are tested to standards by dropping them in a vertical plane on very complex test equipment in a controlled environment. Unfortunately, this is not how we crash on our dirt bikes! 

One of our goals at 6D was to reduce angular acceleration energy transfer, thereby reducing the potential of a rotational brain injury. ‘ODS’ achieved this goal. The 6D ATR-1 off-road helmet reduced resultant angular acceleration compared to traditional helmet designs by as much as 81% during independent 3rd party testing.



LOW-THRESHOLD ENERGY (low-velocity impacts) 

Medical research has provided alarming conclusions surrounding the causes, severity, and long-term effects of concussions. We now know that even seemingly minor concussions (‘I’m fine, I just rang my bell’) may have much more serious effects on the long-term health and well being of one’s brain. It is well documented that concussions occur from impacts in the range of 60 G’s in the adult male and may be location dependent. This value is even less in women and children.

A 4m/sec impact is equivalent to roughly 120 G’s being transferred to the brain in most current model Snell and ECE approved off-road helmets. That’s 100% more than the
energy necessary to sustain a concussion in an adult male! What makes this even worse
is the fact that current helmet testing standard’s only require impact testing at highvelocities above 6 meters per second. These are extremely high-velocity strikes.




Deceleration (time) is your friend during any impact. The longer you can stretch out the event, the less severe the energy transfer will become.

The mechanics of 6D’s ODS technology buys you time and reduces energy transfer. This results in less likelihood of injury or concussion.

Graphs depict acceleration to 70 G’s over time, comparing an individual Snell and DOT approved helmet to the 6D ATR-1. Note the significant increase in time to reach the 70 G acceleration figure with the 6D helmet. Again, time is your friend.


Due to the ODS split-liner system, the 6D ATR-1 flows more air throughout the helmet’s interior than any other competitive helmet. This provides a safer environment for the rider in extreme riding conditions. 13 interior transfer ports vent heat and moisture directly into the air gap for rapid removal to the atmosphere. 8 intakes and 5 exhaust ports strategically designed into the helmet manage the overall system.
