Because in many cases, the way they get the higher octane rating is to mix in more alcohol. So while you think you are treating your bike, you may in fact be abusing it.
FYI, the higher the octane rating, the SLOWER the burn - which translates to poorer performance. The only reason to use higher octane rated gas is to prevent predetonation and pinging in the engine. I've personally never heard of a modern engine having that problem and certainly not the Ninja.
