I took a long run recently on motorway and got 56-58 mpg on my 1700. Thats uk gallons at 65 mph . Stop start is a different matter of course.
Dazco, no mistake, I'm reasonably good at math.
Standard My2010 1600.
after I filled up the computer showed 433klms to empty or just over 20klms to the litre.
Maybe I don't ride as hard but I do my share of high acceleration and top speeds of in the 120kph range on good roads.
Btw down here a gallon equals 4.55 liters and a kilometer is 5/8ths of a mile.
