I switched my old Schubert S1 for a Scorpion air 1400 - carbon mat.
The main reason is: nearly one pound less with the new helmet in comparison with previous one !
Less quiet ride but my cervical vertebrae say thank you after every ride...
It is the Bell Race Star DLX-Solid which obtains (only) the best rating (3,5/5) from the lab Certimoov (3rd campaign of tests since 2019) and it is the only full face getting this rating (among the helmets available for the test) :
They explain that the future 22.06 European standard does not take enough into account the protections to prevent damage from the brain rotation. However they explain that the point "ZRot" (rotation as when we say no) of which the brain is very sensitive, is planned to be added in a next phase, probably within 2 years time.
I have several crash helmets, Bell M6 Carbon, Roof Boxer, Simpson Bandit, Shark something or other. But my favorite and the one I like best of all is the Icon Airflite.
Have had many helmets in my life. Used to wear half and 3/4 lids. Then one day I saw the light and started wearing full face. Found that Shoei fit me best and am now wearing a GT Air. Tried a Scorpion once but sold it as I thought it would fit but after a long ride it wasn't gonna work.
