Suzuki makes really good bikes. I bought a GS150R in 2009, and it still rides like new today(2016) after 75, 000 kms. And I get a consistent 50-55 km/l in city driving(same on the highway as I ride fast at 80-90 kmph). Gixxer looks very good. If I were to buy a new bike today, it’d be the Gixxer!
And by the way, GS150R used to be the only bike which had a gear indicator in it. A super useful feature which many manufacturers choose to omit .I am getting mileage 53 in city. Highway I am getting 56. Mileage depends on ride quality if u ride between 50 kmph u ll get this. Once I ride my bike above 122kmph I got only 32kmph.
