Q. I am 5.4 ft, which bike is comfortable?

This was wrong answer dude because NS200 it's a very good bike but not for 5.4feet height because your leg won't touch ground and while sitting and parking you will 100%find uneasy thinking bike may fall it happened with me and I sold ns200only in a year met accident too but this bike is the best racing bike real passion

Classic 350 or bajaj avenger street 150/180/220 if you prefer a relaxed ride,else go for pulsar ns 200 or Apache rtr 200 4v.

RE 350 classic will suit you. In case minor height adjustment required you alter seat . Go ahead
