When your reserve light comes on, you still have about 4 liters of fuel, good for another 80 to 90 km of city riding, so you're over 300 km range in city riding.
My mileage in stop and go city traffic also hovers around 5 liter / 100 km, but when riding on the highway, at an indicated 120 km/h in 6th gear, the engine is spinning at 4000 rpm and my mileage computer is showing consumption of around 3.9 to 4.2 liters, giving me a theoretical range of 400 km on the stock tank plus another 125 to 150 km with the additional 6.5 liters in the Adv tank. When I'm riding backroads with lower speed limits, I'm usually riding at 100 km and my consumption is even less than 4 liters / 100 km.
I have yet to go on a long trip with the new tank, so that info will be forthcoming.
