Nothing against your comments mcknatz, I'm just a long time skeptic when it comes to the IIHS.
Motorcycle background has a lot to do with it, they're notably more political than factual in that arena. Note:

They tend to push an agenda & massage numbers to fit, making all their reports somewhat questionable.
When I look at the comments on that "study" and note comments on "statistically adjusting for age, location, etc." it makes one wonder just what kind of adjustments were made.
It's like the proverbial "just a little pregnant", "just a little questionable" isn't good for an organization that CLAIMS to be objective.
I was happy when the insurance companies that help fund them didn't all believe their listing of "Sport Bikes" that deserve higher rates for being dangerous. My Honda Gold Wing Touring Bike was one of a number on the list that hardly deserved that kind of rating. Actual rates give a discount instead of a surcharge with most companies, as the loss ratio is quite low for touring bikes.
How does "age" figure into a deaths per million owner years in their results?
Is it skewed on assumptions of what demographic drives a particular vehicle?
And how does that relate to the safety of the vehicle itself?
No answers raises a LOT of questions on their methodology.
