Depends on how the bike is running on what you have been using.
I would say 89 at the least. I get a little drop in milage with 87 which is around 85 octane equivalent with ethanol mix.
They don't use the same formula to get octane rating with ethanol blends.
So if your using the blend your guess is good as mine.
I avoid the "Blends" when ever possible. Only a few places left to get the good stuff any more.
I have run Octane boost in my Legacy Valk for years due to Ignition set to performance settings, I do occasionally put in Lucas octane boost into the B as well. I think it helps it at times. I think it is due to blended gas as well, sometimes the blend is on the low side. Not pushing it, but you might try and experiment with it in a few tanks to see what you think....
You think blended gas is bad now? Wait till the "new" and improved blends come out in a few years!
