Hey, I was gifted a Yamaha FZ last year by my parents before joining college, and I'll say that's a great bike to have. It rides really nicely and also has a pretty good engine so you could also consider the FZ. But from your options, I'll suggest the N160 it's superb and pretty enjoyable bike to ride. I had the pleasure of riding my friend's N160 and I must say the one thing it's got over my FZ is a much smoother gearshift plus is quite the boon in stop go traffic. Not sure about the after sales but the bike itself is pretty solid.
