Wondering if anyone could give me a rough guage on fuel economy for this bike ... Kilometers per tank, & capacity of tank in Litres (so I can calculate very rough cost per kilometre). Understand lots of variables. Perhaps takes as given: Bike in good condition, well tuned. Kind of travelling: be interested in guesstimates for open freeway travelling AND heavy traffic/inner city travelling (stop start, not scooting up between cars ;) ) Thanks a bunch :)
