Its over 100miles. Far better than my old 1198, which was circa 90-95 maybe 100 just. Plus I press on. I'd guess 110 ish + reserve.
I used to brim my 1198 when I was doing distance. If you try you can squeeze a bit more in. I had to as my mates were on an R1 and Sthou and I was the weakest link. No more am I with the Pani. Nearly got caught out on way to alps one yr when our scheduled fuel stop was being renovated. Plus it was late. I had to practically coast to the next stop and I was on fumes. I got 25m from reserve that day.
I keep going faster and faster and its getting lower and lower its catching me out every now and again just under 100miles to reserve and 115 to 125 to empty
I've had 140 out of mine, all motorway and riding at a steady 70. Light was on and I was about 10 miles into the reserve trip. P.s It's very hard work sticking to 70
