Since you have mentioned that this will be your first bike and you’ll be spending most of your time within the city, the TVS Apache RTX 300 isn’t the ideal candidate for you. It is quite a tall and substantial motorcycle with decently punchy performance too and wouldn’t be the most welcoming machine inside the tight confines of a big city, especially so for a new rider.
If you are in the market for an ADV, we’d instead recommend the Hero Xpulse 210, which will be lighter, more manageable and friendlier for a newbie to motorcycles.
If you decide you want something sporty, then the KTM 250 Duke would be a great option to start with. It has energetic yet friendly performance, great handling and features and will also be decently fuel efficient when ridden sensibly.
Take a test ride of these bikes to see which one suits your riding style best and feels the most comfortable.
