Q. I can afford for NS160 but in power will it beat Apache RTR 160 and give performance as possible as NS200?

It won't give the performance of a NS200, just like a Honda Amaze not giving the performance of a Honda City. NS160 should do better than Apache

Ryr 160 yes but will be definitely less than 200detailed specifications can be reviewed @ https://www.bikewale.com/m/bajaj-bikes/pulsar-ns160/specifications-features/?utm_source=google&utm_medium=cpc&utm_campaign=Sitelink-Feed&gclid=Cj0KCQjwo7foBRD8ARIsAHTy2wm5bm-ocisjyeyx__5p2osw91o3CZfX1WR6if1ALQMk5m99WfrB6-gaAroIEALw_wcB also

Ns160 is good on average and dependable, whereas in terms of handling and control RTR is best
