Yesterday I rode a 273 mile round trip to Geneva-On-The-Lake Ohio just to get a dog and a root beer at Eddie's Grill for lunch.
Yeah...I do stuff like that.
I came home with a box for donuts, too.
I'm still a bit surprised at the variance in responses regarding range.
I took off with a full tank and filled up again at my destination, then once again when I got home.
Figuring about 135 miles each way, there was still a bar showing on the fuel gauge and a second bar flickering when I got there. (No, I don't rely on my fuel gauge for anything but an estimate, but I'm just saying.)
I was getting the same reading when I fueled up at home.
Doin' the cipherin', it looks like I was getting a bit over 45MPG.
The trip was mostly highway with posted speed limits between 65 and 70 mph. Not a camping trip, so the load was light.
I still wouldn't want to chance running out, so I usually stop for a gas no longer than 130 miles (usually less) on trips.
One trip (plus my experience from last summer's riding) is not a big scientific sample, but it least gives me some conform that I'm regularly getting the same results....at 130 miles, I still have some gas to spare.
