Its mileage is 45-50 in city and 50-55 on highways, which is almost good. it is petrol type and its capacity is 12ltrs, definitely not bad. whta all customers wants this specific.sure this bike can compete for its capability with compare to other bike. even you are riding on roads filled with potholes, you would be able to handle the bike with ease. the bike might give impression that it is low on power(15bhp) when compared pulsar rs200, yamaha r15, honda cbr. you will realize that gixxer sf is little bit more powerful for a 155cc bike.comfort bye is gixxer sf does not vibrate even at top speed and its seat comfort is awesome, I challenged you wont feel pain.so my suggetion is you must have to ride once on gixxer sf, I challange you this bike will give more satisfaction.thanku
