I go about 10 to 15 minuets to the local coffee shop. But my stereo is on max volume the whole way there!!!! Oh, and I rev her up at the red light to. Cheers 
Hahaha 2 funny, me too, at least on the highway part of the ride

I do this no matter the weather except icy and/or snowy roads. I have only missed 2 days this winter, unusual to say the least, and I also try and do all my errands after coffee. If I can spend this much time on my bike for the rest of my life, well, I will die a happy man. I grew up with a scooter as my primary ride and more often, my only form of transport... I used it to ride and think through problems, to have fun, to learn to take risks, to... well, everything... I live that way a lot today, in the moment, using my gut to guide me. It re tunes ME!!

But to answer the OP, it depends on who I'm riding with. With my wife, it is about 150 miles before she needs fuel in her CanAm three wheeler. Without her, probably 200 miles or so before I gotta have gas, unless I'm with the guys and we are in a hurry...
