Yamaha FZ-s comes with single cylinder 153cc engine which generates 14PS power and 13nm torque great to ride good looks and feature and build quality of yamaha is great but lacks pickup and some power but has good road grip and the rear wide tyre looks good. milage is good as it is yamaha mine gives 45-50 but depends on youe driving style on highways gives 50+ I am using fully synthetic oil. it helps to get more mileage
