More octane? Why? If you aren't pinging on 91, you don't need more, and having more won't produce any benefits. Remember that 91 octane as tested and posted on US gas pumps (R+M/2 method, or AKI) is equivalent to around 96+ Research Octane, and 95 RON is all that the book calls for.
You might get a higher quality fuel than you can buy at the pump, and your performance may improve marginally as a result, but it will not have anything whatsoever to do with the octane number.

Octane in excess of what you need causes no problems whatever. Fuel of the wrong type, not properly jetted can. High performance gasolines formulated to be oxygenated, such as VP u4.4, require larger jetting to offset the oxygen content of the fuel.
If it's just smell you want, by a quart of Maxima 927 and drop a teaspoon in every full tank. Much cheaper.

Ok so with that VP fuel it's leaded is that any cause of concern? And also my bike is FI so I'd just have to get it remapped for the oxygenated race fuel? (There's a lot idk but I thought jets were only on carbs)

... race gas is refined way more than pump gas,
No it's not, it's just a different formula.
Depending on the quality of your local pump gas, you might gain as much as 2 HP from using something like U4.4. If it costs $12/gallon, and you ride 50 hours in a year, averaging 40 mph, and get 20 mpg in the process, that's $800 a year extra for those two HP, every year until you decide to give them up. The right exhaust cam will give you that for a $200 one time expenditure.
