What do the numbers mean? 5.7 what?
But, I do agree that a lot of it has to do with the rider. A lot of these younger kids seem to have no fear, feel they are invincible and a lot of times lack brain cells (see a lot of them on their repli-racers with shorts, flip-flops and t-shirt). I am going to say that 99% of the time it is the rider, not the bike.
