No, it's not. It's just that you ask for advice then sidestep all around it, it's getting to be not worth typing.The manual says “equal to or higher” and it mentions 91 as well. Which is why I asked the question in the first place. Is this some triggering subject for some reason?
I gave you the reasons why, if it means nothing to you, then by all means, go out and get racing fuel for your bike. I cannot stop you from abusing your engine.
The RON method is a lot different from what's normally used to rate octane, so you can't compare the two numbers to each other.
