Since I ride all year, at least every month of the year, I don't worry much about the gas in my bike.
But I have had a snow thrower and a lawn mower end up with a gummed up carb many many years ago.
I've since used Sta-Bil in anything that sits for more than a month without burning fuel and have had Zero/None/Nada issues yet. And that is even though there is e10 in the tanks all my gas powered lawn or snow equipment starts right up at the beginning of their respective seasons without even a cough or excessive attempts to get them started.
Historical experiential evidence ensures continued use of Sta-Bil for the foreseeable future.
If I see that I won't be riding the bike for a month or more I'll put in some Sta-Bil there also just to hold it over until the next ride. If I don't ride within a month that means it will be somewhat longer before I burn off enough of the tank to fill it again with fresh so...
Modern fuels can usually last a few months without any special treatment. Sometimes longer.
Oh, and keep in mind that any water absorption tests that I've seen are with an open container. That is unrealistic. Your fuel system should be a sealed system so excessive moisture should not be an issue in the first place. And also ethanol does absorb moisture, and as this video indicates will hold moisture in suspension as long as it isn't excessive. That means any moisture being held will flow out through the system as the fuel is burned. If moisture IS excessive then you would be looking at much bigger problems with your fuel system than just a little extra water in the tank.
I'll bet I can make flying in an airplane look at least 5 times more dangerous than riding a motorcycle!
