Thrashing round known roads dash says 48 ukmpg. Touring with cruising and the odd thrash thrown in 56 ukmpg. About 150 miles to a tank is a good time to fill up generally.
Thanks Eldon I do not have enough experience for expected range. I am looking at an spirited adventure ride in Kansas on 2 lane back roads on Saturday. Most small towns or villages around here no longer can support a gas or petrol station due to very expensive regulations. So at 120-150 miles I probably won't make it. Google Earth preflight showed no promising fuel stops or even coop grain elevators that sell fuel. Much less on the weekend. May have to abort or rely on finding a farmer who will let me fill out of his 300 gallon tank unmetered tank
Just go and do it, you'll work it out somehow I carry a petrol stove which I keep topped up so I always have a one litre bottle spare in my bag. I have had the mileometer reading minus 3 miles (reset trip at zero) when out one day and it had about half litre left at next station. Pictures are on here with more detail under triumph rideouts or something similar. Carry a couple of of sigg bottles in your luggage just in case.
I get about 110-120 miles before the fuel light comes on; and although I've never run until empty (who would!) I can get ~30 miles with the light on, had a rage of zero miles showing for a while once which was disconcerting. I'm quite heavy handed though, over 7k miles and most of those have been pinning it for the fun
Just for general info; 765 RS '68 plate. Filled up yesterday with 2 miles showing on the dash as the remaining range. It took 14.44 litres of fuel to brim it.
From the information that followed this message it looks like you'll be fine! I hope so because I think there's more than a few of us want to see some pictures of the ST in the remoter regions of Kansas! GO FOR IT. Nothing ventured ..................................
174 miles today/yesterday from a brim full tank to dash range zero. I'd guess less than 2 litres left so a "safe" range of over 180 appears quite possible.
I managed 88 miles before the fuel light came on the last tankful on mine. Mind you, some of that was on the road which helped squeeze a few more miles out of it!
