younger riders also grew up and still grow up with an everything to the extreme thrown at them,,computer games where you get many lives,the stunts the crusty demons pull off make evil kenevil look like a jerk,and its also attitude,,its not every young rider just a hell of a lot of them,,i see where your going with the manufactuers angle,we had an australia wide 250cc only law for learners here started in the late 70s because anyone could go and buy a "kwaka 900"and display the "L" plates,thats since been changed now and goes on a power to weight ratio,its cars aswell,although a smash is more likely to be survived,its not so much the high speeds as much as the peer pressure and foolish behaviour,lack of respect and training,,none of us are angels here and have done and still do our fair share of scallywag antics,there is a zone i for one dont enter though.
