I got new Yamaha FZ-S a week before. Its very super to drive. Smooth engine, no vibration, etc etc. Mileage is dependent on our driving. I am getting 45 on city and 49 on highway. The new 2013 FZ-S has some good features like average mileage, seat at back differs from old one.
I will wait for some days whether the mileage drops or increases. Any way the bike is super, surely it is the LORD OF THE STREETS.
