65mpg at 40mph in 5th gear x 7.7 gal = 500 miles per tank!
The ST1300 has a two-element fuel-tank which lowers the center of gravity and provides an exceptionally large 7.7 US gal fuel capacity. This normally gives 42mpg and a range of 320 highway miles at 70mph.
I rode the Dalton Highway north of Fairbanks Alaska in July 2010. Extremely slippery, calcium chloride saturated mud required me to intentionally drive in high gear at low speed to eliminate over-torque, wheel slip and subsequent face-plants. The trip computer consistently registered over 65mpg while I averaged 30-40 mph for 450 miles up from Fairbanks through Cold Foot over the Brooks Range and 5,000 ft Atigun Pass, to Dead Horse on the Arctic Ocean. I then returned 450 miles back to Fairbanks. These conditions (low speed + high gear) extended my one tank range from 320 to 500 miles.
The ST1300 was absolutely trouble-free for the entire trip, my only issues being tire wear/failure, multiple headlight filament failures, broken mirror glass, a mud-encapsulated radiator, altitude-induced air in brake lines, and a broken belly fairing.
Not too bad for 13,000 miles and successful completion of an extreme long distance ride from Key West and back. The IBA calls the ride from Key West Fl to Dead Horse Ak and back "Ultimate Coast to Coast to Coast Insanity".
