As Mike say it's the MON thats more important.
RON is just an indication of knock resistance at light throttle.
MON tests are carried out at higher temperatures and higher RPM.
I didn't think a MON of 87 was particulary good for a 99RON fuel personally.
Can't remember what the MON of Optimax or ESSO SUL was though.
Not that it bothers me anymore, bike will run on anything
