Wow...that fuel data is impressive!!
Few years back I had an Aprilia TuonoR with modded TB's.
On a run down to Swizerland a few years back, one afternoon, it averaged 26mpg.
Mate did the same run in his TVR Chimera a week later, and managed 27mpg.....

The road in your vid looks great....I think I've ridden it....not sure...
Where please?
