While the three bikes you’ve shortlisted are certainly comparable, they offer very different riding experiences. The Yamaha XSR155 is the sportiest of the lot, with stiff suspension and a slightly leaned-forward riding position. On poor city roads, this can get uncomfortable, although it is the lightest and most fuel-efficient option here.
The TVS Ronin and Royal Enfield Hunter 350 are roadsters with torquey engines and neutral ergonomics, as well as plush suspension, making them suited for city riding. Neither of these bikes can match the XSR’s fuel efficiency, though.
A test ride of these 3 should help you decide which one suits you best.
