Kinetic k4 100 zx is a very much fuel efficient bike.it gives s mileage of 70-75 kmpl in city conditions. but this is not a smart looking bike. this bike is better in mileage only, in all other fields this bike is not so good as it should be. the person who want only fuel saving bike, they should purchase it, but the guys who want looks and riding pleasure should not purchase this bike.
