Considering your stature, in the Yamaha stable, instead of the MT-15, we'd recommend looking at the new XSR155. While both are mechanically near-identical, the XSR is a more spacious machine than the MT. Since this will be your first bike, the XSR will prove to be the most manageable and approachable. Thanks to its lighter weight and unintimidating power output. 

The Bajaj Pulsar N160 you're considering is a good option, but it will be the slowest of all the bikes you've shortlisted. However, if all you're going to do is potter around town, then getting the Pulsar makes sense as it is the most city-friendly bike here. 

Coming to the two Pulsar NS models, the NS200 will feel quite sporty and engaging while still being friendly enough for city use. However, the bigger NS400Z isn't the most city-friendly machine. Also, it will return lower fuel economy owing to its larger engine. 

The Honda CB350 models are very different to ride, thanks to their neo-retro leanings. It will be the most comfortable and relaxed machine of all the bikes you're considering. Lastly, the TVS Apache RTR 310 is actually quite a capable do-it-all machine, and will give you room to grow as a rider, too. 

Since you are considering multiple bikes with different riding styles and at very different price points, we'd recommend you first decide on your budget.  After that, choose within that range accordingly. Also, take a thorough test ride of everything you shortlist. 

The TVS Apache RTR 310 will be a good step up from your current Apache RTR 180. The RTR 310 is a sporty machine with good performance and handling, which doesn't feel overly stiff or uncompromising and makes for a good all-rounder. 

As you have pointed out, there have been sporadic issues with TVS' aftersales. But if you are prepared to deal with them - and it does seem like your heart is set on the Apache - then you can go ahead with the RTR 310.

If you are open to looking at other brands, the Bajaj Pulsar NS400Z, Triumph Speed 400 and KTM 250 Duke all make for genuinely capable alternatives, with the Bajaj and Triumph also offering you quite a bit more performance. 

We would urge you to take a test ride and speak to your nearest dealer for aftersales of each bike so you can make a more informed decision. 

Both the Bajaj Dominar 400 and Triumph Scrambler 400 X are reasonably reliable and hassle-free machines, and considering they are both made by Bajaj, they should be light on the wallet in terms of maintenance. We recommend choosing the one you are more comfortable with and the one that has a service centre close to you. 

Coming to why we haven't reviewed the 2025 Dominar 400, that's because the bike is mechanically the same as when we reviewed it last in 2021, and the only tangible difference is the new LCD borrowed from the Pulsar NS400Z.

If you are comfortable with the size and heft of the TVS Apache RTX 300, then it is certainly worth considering because it will fit your needs quite well. 

If you want something in the same price range that is lighter and more manageable, then bikes like the Bajaj Pulsar NS400Z and the KTM 250 Duke are worth considering. 

Take exhaustive test rides of all the machines you shortlist before you decide.
