Thank you far fast replays'.
I need performance(good accleration,top speed not matter much)+mileage(35+ all times with moderate ripping),so these confusions.
I have dropped the plan of 180s as their performance is not upto the mark,as most of the times I will be riding with pillion,
I have also heard ZMA,ZMR,P220,R15 and even FZ mileage dropping below 35,so Is there any ways to always get mileage above 35?
