Since you are already familiar with the TVS after-sales experience, we would recommend you take a look at the TVS Apache RTR 160 4V.
It is a smooth, comfortable, fuel-efficient and feature-rich offering. However, do bear in mind, it can feel cramped for larger riders, so we'd advise you to take a test ride and figure out if that is the case for you. Another option to consider is the Bajaj Pulsar N160, which has similar attributes to the Apache bikes but is a more spacious machine.
