If you watch the whole scene, the rider clearly had good visibility (the inside of the corner is wide open and viewers have parking and standing room), reasonable speed, and some lean angle left. This is an excellent example of target fixation. Rider comes through curve well to the inside with lots of room to the shoulder. Rider sees the bikes, panics, gets on the brakes a bit, stands the motorcycle up, and fixates on the target. It looks as if the rider is aiming right for the bicycles, instead of the escape route in left half of the lane (where he was in the first place).
