I'm pretty sure RON 91 is 87 in the US, so I think you're fine on that. I can't imagine a 1987 ninja 250 needing 91 octane gas.

I'm 12.65:1 and only have to use 89, I wonder if there are any bikes that require 91? Probably a Ducati or something else exotic and Italian. I've always heard running too high an octane can decrease performance (like 91 if your bike wants 87), but I have no idea if that actually is noticeable in real life.
