Well, when you start looking at octane make sure what grading system they are referencing.  In the US and Canada the octane ratings are what is called pump octane.   Pump octane scale  is a lower number than the research octane scale used in Europe and Asia.   If your scooter calls for 92 octane RON then that is the same as 87 octane AKI (R+M)/2, in US and Canada.  My little Japanese Honda CH80 calls for 92 RON in the tank but that is Regular gas, 87 Octane here in US, Canada and in Australia and New Zealand.  

You are correct in your statement about different ratings. This is where things get a bit messed upped. In most cases, if the fuel requirement is RON it will state 92 RON. According to Ice Bear, their fuel requirement is based on US rating not RON, because the machines are export design and something to do with the EPA and all their crap.

I been using 87 octane Regular in my (2) 50cc scooters for 3 years without any ill effects. Never yet heard any pinging. After driving it for awhile, i noticed a small sticker by the gas cap that said to use no lower than 90 octane, but since i had already driven it with a lower grade i continued. One scooter has 7K miles and the other has 5K. And this is in a mountainous region with many hills.
