Go for it if you plan to have them not more than 4 years.
getting spares is time eating , and new bikes develope problem very soon , which are negligible and after some years they become a major one.
My friend has one , recently he spend around 5000 /- for head and piston works . earlier he spend around 4000/- , he spends as it was his first bike and will not sell it.
I have a apache 150 , the common problem in it is tappets sounds emerge and in every year at service it must be rectified. , engine wise its refined and gears are hard compared to pulsar , but you'll get used.
No idea about the 160 etc
people have said suzuki bikes are fine to ride , no idea about its cost and spares!
