I bought Yamaha FZ-S a year ago.its a gud byk but I dnt suggest to the people living in hills. I mean the places like shimla, manali etc.because its pick - up and mileage in hills is very poor.no doubt its the best bike one can have in plains, but for the hills. naaaaa.
What else, when you are riding it on the highway.it feels awesome. it flies in 5th gear with maximum of control. If u are planning to buy 150 cc bike.go for Honda or very common pulsar.
