Re: Low Fuel Warning R1200R
Don't trust the fuel gauge! Many R bike owners have experienced false readings due to fuel strip failures (the fuel strip is a gadget in the gas tank that transmits the fuel level reading to the gauge).
My experience with the R1200R is that I obtain an average mpg between 46-50. Your experience may be different, depending upon how fast you ride, braking, terrain. etc. If you do the math and multiply 46 times 5 (the capacity of gallons in the tank), you get 230 miles to a tank. If you multiply 50 times 5, you get 250 miles out of a tank. Either way, you can see that you need to refuel at about the 200 mile mark, to be safe.
I set the trip odometer every time I fill up and when it gets to 200, I refuel. As a backup, I also set the fuel gauge calculator on my Garmin Zumo, each time I fill up. I have it set to alert me at 200 miles of travel, just to give me a contingency, in case I am not paying attention to the trip odometer.
