Biltwell Gringo ECE 22.06 ECE 22.06 is a helmet safety rating that extends and increases the testing requirements of ECE 22.05 (with 22.05 being a more modern, more comprehensive European alternative to DOT). With 22.06, 12 additional impact points are analyzed (now totaling 18) and impact speed is increased (from 7.5 to 8.2 m/s). Unlike DOT, every ECE helmet model must actually be tested by an independent lab before it receives 22.06 certification. HelmetStill the same Gringo you've come to love, the ECE 22.06 -rated Gringo Helmet has more EPS foam on the inside, with EPS foam in the chin bar and closed cell BioFoam in the forward area of chin bar for additional impact protection.
