I have a tinted insert for my shoei so if I am out late in the day or into the evening I can remove it and go back to clear visor. Its simple and quick to fit and looks fab.
Always remember a mate being caught out at night with only a black visor and having to ride home from Cheddar in the pitch black with the visor up..man that was a scarey pillion ride home.
I am not sure about the legal stance on them but as my bike and leathers are black the visor had to be too!!
