Let's you get to write some of the rules for how insurance companies surcharge bikes. How would you suggest they choose what bikes are affected by a supersport surcharge and which arent? (Picking "none" or impossibly restrictive criteria will get you sent to detention).
Example: Only bikes that were originally marketed as supersports. Gets bikes like the Ninja 1000 and ZZR600/1200 off the hook, but may retain the surcharge for older bikes that are not in the same strata as modern supersports (e.g. Honda CB750F)
Example 2: Clinton Assault Weapon Ban style rules where individual features don't necessarily make a bike a supersport, but combinations do. E.g. If a bike has clip-ons, AND is fully faired, AND makes more than, say, 80HP, it's an SS. Will exempt slower bikes but may accidentally re-encompass bikes that were already loopedholed out (some VFRs possibly)
