They are not designed to protect you against the same amount of force as a motorcycle helmet.
That study just proves that expired bicycle helmets are still good for bicycle accidents, not motorcycle accidents.

You rest your case? You haven’t presented any real evidence in support of it.
You are free to throw your helmet away every couple years if you want to.
