Well lets start with its most amazing part and that is its timing, if you want a sport bike+family bike with in affordable price than no more thinking go ahead with Yamaha FZ S FI V2 because its performance on road is really good enough for a person with sporty outlook and if you want something like a 100 cc bike like slow on road also it fits, overall its good in performance and also I noticed it doesnt make big problems on milage like I expected.
Its performance is really good on the same time if you wanna modify your bike this one fits for that too.So over all he is good to go and in milage also I am satisfied but I wont say you will get 45 to 50 and all but it can manage around 40.
