    Europe uses a different rating system than the U.S.and Canada. The U.S. Octane numbers are 4-6 numbers lower than the European numbers for the exact same fuel. So if it requires 98 in Europe, it's 91-93 in North America.

    No, it calls for 89 AKI, which is RON or ROZ + MON/2. 98 RON or ROZ =93-94 AKI. 95 RON = 91 AKI

The only time premium might helm is if you have a knocking problem, and if your new bike knocks then something is wrong.

    As to ethanol, I only have corn gas available and none of the theoretical issues have bit me. The longest I've had a bike sit with untreated corn gas in the tank is 3 months and it started & ran fine. I will admit that I'm not a 10/10 rider so I would never notice a 10% decrease in performance, would you?
    You have the logic or really premise wrong. It can run more advance with higher octane which produces more power. It can run on lower octane than 91, but it will make less power and probably get worse gas mileage.

    sMiling because sometimes you just have to use gas with ethanol
    I've noticed a dip in gas mileage of late. About 10%. I wonder if it's winter fuel?

    I believe the technical term for it is "crap gas".

    If those were my two choices I would use the 90 AKI. The owners manual says use 89 AKI and given the choice between meeting that with ethanol or without, I'd choose without. Around here where I live, there's no gas available other than at a few marinas that have no ethanol. 89 AKI (US rating) is equivalent to 95 RON. My choices are 89 or 93 AKI and I haven't seen any difference in mileage or performance (on my butt dyno) with either choice.

    Could be. The gas here in AZ sucks. I never had pinging until I came here and I am not talking about in the high heat either. It's like they put 87 in all the tanks in the stations.

    It says 89 AKI minimum. At least that's what mine says and it says it on the gas cap too. That's minimum, not recommended. 98 RON would be optimal, which is 93-94 octane. 91 is the highest here in AZ that I can find for general use.

    I have well over 26k on my bike, and have had no real trouble with any grade of gasoline. Here on Cape Cod, I have zero options for ethanol free, but I have had no issues anyway. I use 89 a lot, as its more cost effective. I'll dump higher octanes in when Its me, the wife, Tobi the border collie, and our huge trailer, but, I've had to run a couple of consecutive tankfulls of 87 through her with this configuration as well. All I've noticed is a 'slight' lack of power and a little knocking, WHILE at elevation when doing this, but ONLY when I have us at/over GVWR for the bike anyway. I am not sure a 93 actually gives you much of a performance boost anyway, as it burns slower than 89? I forget the many threads I;ve read on it, but that seemed to be the gist of it.

    Looks like Cataumet is close with some awesome octane in the ethanol free flavor.

    If you interested I'd give them a call, a lot of marina fuel suppliers will sell to vehicles. Maybe I'm misinterpreting the racing logo and high octane ratings at land based racing verses boat racing. I would assume those octanes would be way too high for your standard 2cycle low compression outboard motor.

    That is one problem with the pure gas app. It sends me to marinas that are often closed or won't sell to vehicles. I learned to avoid marina type locations on that app for that reason, there are a few exceptions to the marina problemo.

    Lots of boats use old rubber lines (like mine with a I/O V8), so Marinas typically use ethanol free still (around here). Loud will provide "racing" ethanol free, by the can, but not at the pump.
    I am not sure 'if' they can actually sell it for road use, or why there are so few places to get ethanol free in the entire state of Massachusetts in general. When I purchased their BioDiesel, I'd have to pay an additional road use tax for it, unless I brought my 6-6gal gas cans and only filled them, but not the truck.

    Besides, the Cataumet station is 20 miles from me, and the next closest is over 90.

    My high octane ethanol free gas stations are usually about 20-45 miles away. I've learned to accommodate the distance, by scheduling a "gas trip," gives me a good as any excuse to get out on the bike. Looking at the ethanol free site I was surprised to see how few stations there were in Mass. I suspect there is a political motivation on that one. I would expect the corn states to have nothing but ethanol fuel as it promotes the AG industry of their state. Not sure why the north east would be so anti-petrol. Learn something every day, minus the why of course; why is rarely answered in these manners.
