How do you remove the visor from a AGV S4 crash helmet?
With Arai helmets you usually remove the visor as follows: Place helmet in front of you and with visor fully open facing towards you. Now push the bottom edge of the visor outwards near to where both the side covers are for the hinge mechanism. Whilst doing this keep pushing the visor upwards and it should come away from the hinge. Sometimes you need to use a fair bit of pressure to do this!
