Fuel capacity

Yeah, I think the R3T gauges are conservative but not as bad as the others. The mileage remaining number on the trip computer on mine jibes pretty well with the calculated range from 6 liters (used to say 60km to go, after my recent long run where I dropped the average to 6.4l/100 it started saying 90).

I put 6.3 gallons in it once, in the Mojave . I am glad the petrol station wasn't any further away or some pushing may have been required. That is not something that I wanted to do in July.

My Roadster light comes on when it says I have about 75-50km left on the tank. After it hits 0, I can still ride for a bit and then when I fill up I usually put in about 21.5L

IDK67 any idea what your distance was when you filled to 6.3? Morbidly curious

I can't remember, but it would have been around 200 miles. For some reason the economy on that tank was a bit lower than average. Normal crusing at around 70 mph will give 38 mpg without a problem.

So with the Rear tire spinning and front in the air,you would expect maybe less than 38 MPG? just to be clear

Ha.

Convert the curry-burner to diesel and off you go. My light comes on at 230kms. Takes about 18litres ish. I want a 40 litre tank.

Normal cruising at 70mph will get you run off the road by white van drivers here.

I said it before and I am going to say it again. Unless there are major differences between the 2005 model and the later touring versions, putting 6.3 gallons in the tank of a Rocket III is pure sci-fi to me and I'm going to tell you why.
The low fuel light on my 2005 comes on at about 109 miles. The first time it happened and being new to the Rocket I went straight into a gas station and filled up. To my surprise it only took between 3.5 and 4 gallons. "Knowing" that the tank capacity is 6.5 gallons I figured there were at least 2.5 - 3 gallons left in the tank.
Next time the low fuel light came on I choose to ignore it trying to accomplish what people like you have accomplished. 200 miles on a full tank of petrol. Guess what happened next? I ran out of fuel with 154 miles on the clock. When I refueled it only took 5 gallons which shows me that you don;t actually have 6.5 useable gallons. So if you don't, then how is possible to get even 180 miles out of a full tank? If when you refueled you were able to pump 6.3 gallons into it, it means you have an alternative energy source for your bike. That it runs on some s h i t you are not even aware of. Can someone explain that to me? How is it possible to get that many miles and put that much petrol in this bike?

If you put the nozzle all the way in the tank when filling up and wait for it to stop automatically like you do with your car, then you will end up with a 5 gallon tank. If you fill it to the bottom of the neck then you will have about a 6.3 gallon tank.
