The manual states tank capacity is 14 liters. I add gas just when fuel empty starts flashing and maximum I do is 10 liters. So fuel reserve is 4 liter. At the average mileage of 25 KM per liter so the reserve should be 100 KM !!!
I ran out in the drive way after doing just over 50 km on reserve, averaging 4.8L/100Km. This suggests a 2L reserve. I could only then just get 12L in my tank? But I was filling up to the bottom of inner cup. I think the tank has 2L of wasted 'breathing' space. I can comfortably get 250km out of the bike when I ride as hard as I like around town.
On the highway or being super gentle I've gotten 300KM - 3.8L/100KM. But I brim it now too.
