I have to agree and lve refrained from commenting on any of these videos but the riding in general is appalling. Approach speed, position of bike and riders positioning is terrible in all the videos. All the gear and absolutely no idea.
Mate, its a nasty hairpin. most riders rarely do any hairpins so don't have much practise. also Most people don't want to risk writing of themselves and their bike for the sake of a few seconds or a photo.
