You must ride very enthusiastically my fuel light usually comes on around 170-180 when touring and the average last year for 2500 miles through France was 52mpg.
Interesting figures!
Bear in mind though with commuting to work and back the consumption is going to rise, though I wouldn't have thought by such a degree - and yes, I do ride enthusiastically!
Me thinks I need to start slowing down with my daily riding.
