I would stay at around 91 oct. You go lower on a bike that revs like sportbikes, you will run into problems of detonation and pinging. Anything 10.5 - 12.8 like mine needs higher oct. I don't want you to think you can't run the lower grade fuels but I would not recomend it. You will pay for it in the long run.....
