The full faring model of gixxer is the only one which is under 1L price. It is best for normal use basically for college students. I am using it from 1year so what I found is;
mileage: 40 km/L for normal use
. 45km/L on highway and long ride with speed of ~ 80kmph
Comfort: basically best for driver but bavk seat is slighted TILTED so when press break person will fall on driver ( which is good for exceptional conditions) .
Style and look is best among under 1L bikes
