bmw system 4 helmet visor change

[ian_dorrian]

Use one of these daily on my commuter bike and i want to change the visor.

Does anyone know how to remove the visor and chin piece.

I am sure it is easy if you know how, but I don't and the angle grinder is starting to look the most promising method in the absence of the instruction book...
