Will definitely get over 500kms a tank. A full fill up usually sets my range at around 560kms. That changes when I do higher speeds as it tends to drink the fuel, but if I was cruising 90 - 110 I think I would get over 600km on a tank.
My range is supposed to be about 50kms less than yours but the engine is so much fun to play with that I hardly ever get that plus I always have the bags on.
