Yes, I logged the fuel usage. It calculated around the same as the computer fuel usage. really pleased with the fuel economy particularly being a heavy bike fully loaded with wife on board. Also, riding in the Pyrenees, much time was spent in second and third gear.
One aspect that surprises me about the new Trophy is that it weighs heavier than the old one. Don't quite know how Triumph managed that, considering all the alloys / Aluminum used on the new bike. Anyway it really is not an issue as it rides superbly.
