With all due respect, theres got to be a mistake somehow. Either in the pump you used for the initial or end fill or something. The best i have seen in U.S. gallons was just over 50. Your mileage would convert to almost 70 U.S. gallons. Seriously.....most scooters don't get that. Must be a mistake. I got 50 U.S. once and that was riding as slow as i could go on the freeways so my fried on a very unstable harley could keep up. Not saying you couldn't get more than i did, but 50 U.S. would be under 42 in UK gallons. So as you can see, there had to be some sort of mistake.
