I hit reserve at around 95 miles and I am out of gas around 130.
Try this website. They list a lot of gas stations in the US and Canada that sell Zero Ethanol.I have always wanted to run mine out of gas to see max out of a tank, but have never done it.
90-120 before reserve needed. Depends where and what riding conditions are.
Probably averages over 100 though.
I wish we had 0 ethonal here. Even though a lot of corn in the area goes to ethonal.
