The manual says, 95-98 RON
95RON=87oct
98RON=91oct

I've heard people say use 89 for best performace...The 91 will take longer
to burn and can actuly decrease performance unless the ECU is mapped
correctly...Also 91 burns hotter then 89...

No sure, this why I am asking the collective...

Thx!

91 does not burn hotter nor does it burn slower. It can resist detonation/pinging better than lower grades.
If you are running a stock bike and your local weather is not too hot, 89 will do fine. However, if you have full exhaust system and/or air filter upgrade 91 is highly recommended.
