There’s been a collision. A motorcyclist is lying injured and unconscious. Unless it’s essential, why should you not usually attempt to remove their helmet?
They might not want you to
This could result in more serious injury
They'll get too cold if you do this
You could scratch the helmet
When someone is injured, any movement that isn’t absolutely necessary should be avoided, since it could make the injuries worse. Unless it’s essential to remove a motorcyclist’s helmet, it’s generally safer to leave it in place.
