My commuting consists of city riding essentially (I live in Paris). 13 kms back and forth. 5 days/week with some occasional errands here and there during the week-end. At the end of the week I’m at 2 bars of fuel left of the dashboard. That’s where I usually top up with approx. 1,5 liter left. I let you do the math.
Other than that, no major issue with the bike. But I wish the tank was a liter or two bigger.
