I think it really depends on how aggressively you ride. I read the review by Motorcyclist Magazine (online) and they claimed to have only gotten 33mpg while I'm averaging closer to 50mpg (US). If I refuel when the warning light comes on it's rare that it takes more than 3 gallons to refill, that tells me that there is close to 1.25 gallons left (4.3 gallons total), and at 50mpg, that's just over 60 miles left. So doing the math, I have close to 90km left when my light comes on. When I ride aggressively my mileage drops to about 40mpg, so even then I'm looking at close to 50 miles or 80km left when the light comes on.
