    R1150RT Usable Fuel Capacity

    I'd be interested in hearing the most fuel anyone has put in an R1150RT stopping at the bottom of the filler tube.

    Is it the same tank at the 1100RT? I put 7.142 gallons into my R1100RT one time......rode 70 miles with the low fuel light on.

    Fuel on an r1150rt

    Last trip, the fuel light came on at about 255 miles. Ended up putting in about 5.6 gallons, so I am figuring about 1 gallon left in the tank based on the books. Will put it to the test on Friday. Traveling 2 up from Central KY to Montgomery, Al.

    2004 R1150RT with 34000 miles.
    I did a 2 up ride on the weekend, 50% highway at average speed of 65 to 70 mph and 50% on country roads with stops and lights, starting with the tank full to the underside of the lip. I did 255 miles when the last bar disappeared and the light came on, I filled the tank
    at 290 miles with 24.5 litres (6.47 us gal.) That works out to 5.25 ltr/100 km or 44.8 mpg us.
    The specs say 6.66 us gallons max capacity tank.
    I've gone as far as 280 miles before the light came on...
    Not sure how much more fuel would fit in the tank if I had tried to add more. After it reaches the lip it takes forever to fill and let it settle in small squirts.
    I have not drilled a hole in the filler neck like some suggest. Thought about it but 290 miles between fillups is probably good enough.

    cheers

    the going rate is 6.6 gallons. And I've drained mine a few times and refilled with exactly that amount.
