Q. Which bike is the best under 160 cc segments? i am confused which bike should i gor for, please recommend me - Pulsar NS160?

1604v is better in every aspect when compared to ns 160. Bajaj ruined ns series by not providing a single update. The only reason to buy ns 160 at this point would be if you like the ns design over apache apart from that, there is no reason.

If you want speed than Apache 160 4v more power NS 160

I will suggest u ns 160 as I own it since 2 yrs. But u should take test ride first. Then decide
