You don't want to store your bike (for some time) with ethanol containing fuel.
The alcohol scavenges moisture and you can have rusting in your tank and corrosion in your fuel system because of the water content. This also goes for lawn equipment.
If you must store your equipment with this type of fuel, make sure the tank is full, less chance of moisture in the air = less air.
Internal combustion engine aircraft do not want ethanol containg fuel because of the same problem (water accumulating in the fuel tanks). And also there is much higher chance of carburetor icing, which leads to an engine out...not good!
I know aircraft engines need low lead fuel but some small planes have a special certificate for mogas instead of avgas. And some light aircraft use Rotax and the like engines, some home builts use VW boxer motors
I can't remember the term right now, But a gallon of non ethanol fuel has more calories/btu's? than a gallon of the same octain ethanol containing fuel. That is why you can expect more miles traveled to the gallon of fuel...more bang for the buck.
