Riding it hard (120 km/hr plus)i get about 160 then the fuel light comes on. Riding more conservative (110-120km/hr ) i get 210km then light come on. From there in theory you still have 5 litres to spare, so if you have to you can push another 100km out of it, but then you need to have some fuel handy, you WILL die...pushing it also.
