F O RMU L A H E L ME T B E N C HMA R K DATA T E S T I NG Test ing was conducted by two separate independent test labs: SATRA Technology and RHEON LABS *A New Helmet-liner Design for Improved Survivability, in IRCOBI Conference 2016 [online], Malaga, International Research Council on Biomechanics of Injury www.rheonlabs.com/resources HELMET TESTING PROTOCOL Testing the FLY Formula was primarily to confirm that this helmet would provide the highest level of performance and protection across a wide range of impact scenarios. We identified the top 10 MX helmet brands in the world at the time of testing and tested their best helmet models. In total 60 helmets were tested between SATRA and RHEON LABS altogether comprising 150 individual impacts. Three helmets of each model were sent to SATRA to be independently tested to ECE standards, for both crown and front-side impacts. 30 helmets were tested and recorded. Three helmets of each model were tested on a bespoke test rig at RHEON LABS for a wide range of real-world impact scenarios, gathering a wide range of rotational and linear impact data. 30 helmets total were tested and recorded. LINEAR IMPACT A linear impact is any impact in the normal direction of the helmet. These often act through the center of gravity. Most helmets have been designed to protect against high speed linear forces with the intention of preventing skull fracture. However, lower speed linear forces can also cause traumatic brain injury and therefore it is important to protect across the full range of linear forces. Linear tests on the helmets were undertaken to ECE standards by SATRA, an independent test house. ROTATIONAL IMPACT A rotational impact is any impact that strikes the head with any tangential component, these are often called oblique impacts or glancing blows. Most falls in motocross include some rotational element. These impacts are strongly linked to mild traumatic brain injury (mTBI). However, these impacts are not accounted for by testing standards today. All oblique testing was undertaken at RHEON LABS on their bespoke test rig according to advanced testing methods outlined in IRCOBI Conference 2016 paper.* 30 helmets were tested for rotational impacts at RHEON LABS, totaling 90 individual impacts. 30 helmets were tested for linear impacts at SATRA, totaling 60 individual impacts. HELMET PERFORMANCE RANKING CONCLUSIONS Results show the Formula helmet is significantly reducing both the linear and rotational accelerations experienced by the headform during front oblique impacts. A ranking system was developed to rank the 10 leading MX helmets tested. It takes into consideration all of the tests undertaken and outlined in this document – from tests for high and low speed linear accelerations, including HIC scores, as well as for high and low speed rotational accelerations. The ranking also includes a factor of weight, as we believe reducing helmet mass is critical to our riders. The Carbon Formula is the lightest helmet in this range, beating all nine other leading MX helmets. These are the results based on this ranking. Testing concluded the Formula is a very high performance helmet which can significantly reduce linear and rotational accelerations. The FLY Formula is also shown to outperform the competition in an overwhelming majority of cases tested. Totals are the sum of the above test rankings. The lowest number represents the best overall performance.
