I Own FZ-S. It is a Good Racer Bike but when it comes to comfort, it fails. U cant ride for a long time on this bike as it leads to Backache. But one thing I will appreciate is that it runs smooth on rough roads. It is a Strong Bike - Lookwise Rich. Back Seat is Small & so it is not comfortable for Ladies to Sit. Practically it gives average of 40 KMPL when new, but then Average degrades to 35KMPL and this is not bad as all Race Bikes give average of 30-35 KMPL only. I will Conclude that among Different Race Bikes - this is Quite Preferable Bike.
