It is a system that prevents the visor from being opened in undesirable situations. So what are these undesirable situations?
High Speed
Helmets subject to high speed must have a visor lock. If the visor does not have a locking system, the wind will open the helmet’s visor. High speed is over 220km/h to be precise.
Accident
This, of course, depends on the way the helmet is in contact. As a result of the tests and research carried out by us, the opening rate of the visor in accidents is less than the high speed factor. We can say this clearly.
Suggestion: The filtering system on the helmet reviews page can help you find the helmet you want.
