I have just been for a 430k ride around central west where I live, I have a 2017 scout with stage one pipes. I had been riding with a group of 8 and was getting worried if my fuel would last to Cowra. When I reached Cowra I had covered 225 K's and the reserve light did not come on, it took 9 5 litres of fuel which totally surprised me, this means there was still 3 litres left. go figure ! Len.
