If I remember right about the gas mileage most folks are getting around 40 miles per gal....... give or take a few. Sorry but never have taken the time to figure out much on the metric scale.

6.7 /100km comes out at about 42mile per US gallon . 1 US gallon = 3.7L

I cant remember what i get on my 750 but i think my fuel comsumption is at least the same and probably worse.

By contrast i get 6.2 L/ 100km in my Toyota Corolla.

These old bikes are not noted formtheir fuel efficiency.
