160 miles before the last bar starts flashing sounds about right for a 300R.
My 250R will go about 170 to 175 miles before the last bar starts to flash, and that's starting from a full tank where I've filled it to just above the baffle plate. I typically get an average of 70 to 75 MPG, so I know that if I need to I can easily go 200 miles on a full tank without worrying about whether I'll run out of fuel. I once went 220 miles and then refueled, with it taking 3.0 gallons (again to just above the baffle plate). And at that 220 mile mark, I still had about 0.4 of a gallon remaining in the tank to keep the fuel pump running at its operating temp*.
*For those who may not be aware, in-tank fuel pumps require a certain amount of fuel to remain in the tank in order to cool the fuel pump. Which is why you don't want to run the tank dry on a bike equipped with EFI. Doing so will shorten the life of that expensive $230 fuel pump. By the time the tank is at or near empty, the fuel pump has been running very hot for a significant amount of time. Same applies to fuel injected cars, the difference being that replacing an in-tank fuel pump in a car is not a small job, and can run $600 - $800 or more if you have to pay a shop/mechanic to do it.
