Here in southeastern Wisconsin, we can get both, premium with 10% ethanol, or premium without. The differences are very noticeable. Without ethanol, I get at least 8% better gas mileage, the bike runs cooler, and feels much stronger to my butt dyno.
I go out of my way to avoid ethanol fuel if at all possible, and NEVER store the bike with untreated ethanol in the tank.
