Fuel weight and performance

Maybe this doesn't go under "Rider Improvement...", but maybe it does. How often do street/canyon riders think about how fuel levels impact performance and handling? MotoGP riders do think about it, and plan for the impact weight has on cornering and tire wear. As a canyon rider, I don't think about it...I just ride. But sometimes - when my fuel is down to a half tank or less - I wonder if I'm attributing my easier turn-in and overall "skill" level to the fact that my bike weighs about 12 pounds less than it did when I began the ride.

Anybody (not racers/track riders) think about this in the routine scheme of things?

If I know all I need is half a tank of gas for the ride I will only fill to 5/8 for a better ride.

As I can remember 1lt of fuel weight 750grams. To me when I drive at the track it is really important to be light because I can feel the difference. That's why with the telemetry I can see the fuel in the tank with 0.1 lt accuracy .

When I go for a ride, I go for a ride and usually end up quite a ways from a gas station. The little loss in performance because of the extra weight of the fuel in my mind is more than offset by not having to worry about running out of gas. In my younger days I can remember a 5 mi moonlight push (Not out of gas) and I'd like to not re live that. Also if you're pushing it on the street to the point the 15 pounds of extra gas really makes a difference it's time to do a track day.
