Security of Streetfighter helmets

There is already some discussion about whether 50 Euro helmets with ECE standard can keep up with expensive helmets or not. In road traffic, however, you see more and more helmets from brands such as Roof or Bandit, which primarily put value on optics and partly do not have an ECE standard.http://www.bandithelmets.de/xx/index.htm As a rule, drivers of such helmets are laughed at directly as a poser, which should better get a smart hat. m Admittedly, I just like the look well enough that I don’t care about any defects in terms of battery, convenience and safety. Nevertheless, I would like to describe my impression of the helmet and know if someone has survived an accident with such an accident and can contribute experience values. As far as I understand this, the helmet from the above link does not get the ECE standard primarily because of the restricted field of view. FMVSS No. 218 test seems to survive, although I don’t know what this test result says. Personally, I feel the limitation of the field of view as minimal, which bothers me more it is missing chin protection. Although the helmet looks like it is a closed full face helmet, it does not enclose the chin, which is why I can’t imagine that it protects better than a common jet helmet. Purely of optics and riding comfort I am very satisfied with the part, But I would like to know if anyone can explain to me what this American test is about, or if anyone else has had any other experience with these helmets.
