Since you are a beginner rider, getting a bike that is approachable and easy to live with would be our recommendation. Bikes like the Yamaha MT-15 and Honda Hornet 2.0 – both in your shortlist – will offer approachable performance and weight while being quite fuel efficient too.
The Bajaj Dominar 400 – while a sorted bike in its own right – is a heavy machine, which will get quite tiring to manage at slow speeds for a newer rider. Instead, we’d recommend you take a look at the Bajaj Pulsar NS400Z, which offers more performance and features while being significantly lighter.
In case you decide that the power and relatively low fuel economy of a 400cc bike isn’t for you, but you still don’t want to go below 200cc and want something sharp-looking, we’d recommend taking a look at the Bajaj Pulsar N250 and Pulsar NS200. The N250 is a refined, smooth all-rounder, while the NS200 is an engaging and sporty machine.
A test ride should help you make a more informed decision.
