Just received my AMA mag today - it has an article addressing this very subject. I don't have it in front of me now, but the gist of it is that the IIAS "study" is totally bogus. They include bikes that aren't sport bikes and don't include some that are.... with no real research of the age, conditions, license, experience, other vehicles involved, etc.
I couldn't help but notice the fact that some want to ban some of these bikes which include several Triumph models - Sprint, Daytona, etc.
