I got 55mpg while on holiday in Germany a couple of years ago, that was continuos high speed cruising up to about a hundred mph. Filled up at 220 miles and put in about 18 litres, I managed this two tank gulls in a row. Two guys in our group (on Ducati's) could'nt believe it. I reckon 270 miles might be possible but you would be on vapour for the last few miles.
