My opinion based on around 40 years with bikes, is that we are seeing many newbies killing themselves on powerful machines that they are ill prepared to handle. I am a strong believer in "road experience" and not just from a car. I realise not all riders are at fault nevertheless its road experience and anticipation that helps the maturer and more experienced rider survive. The newbies just dont have this. As a rule I always advocate that one wanting to ride a busa or high powered machine should have at least 5 full years of "bike" road experience preferably attending some courses for riders. And for those 5 years a 600 or 750 should be tops. Just my opinion.
