On my yet to fully break-in BS4 P220 with around 4k on the odo, it would be around 525 kms on the 15 Ltrs tank. Now, I haven't checked with full fuel per se. But my guess is from calculating the avg fuel consumption multiplied by 15 Ltrs of tank. I'm getting around 35 kmpl with spirited riding and traffic is a birch in my city right now, all roads become jammed at peak hours. I have to add, my bike has some added weight, like me, so it'll be like taking a pillion all the time for an avg guy.

I'll be air for next service at 5k to start tracking actual fuel consumption.
