Since you are a taller person, we would recommend you look at the Yamaha XSR155 instead of the MT-15 as the XSR is a more spacious machine which will be useful to you. For a similar price, you will also get larger machines like the Bajaj Pulsar N250, TVS Apache RTR 200 4V and Honda CB300F. It will offer you better performance at the expense of a small hit as far as fuel efficiency is concerned. 

Since you have mentioned that you are considering the Honda CB350 models. Do bear in mind that these are relaxed neo-retro roadsters which will offer you a more laidback riding experience and good comfort levels. Although fuel economy will be quite a bit lower than that of the smaller bikes we have mentioned above. It is also worth taking a look at the Royal Enfield Hunter 350 because it offers a similar experience to the CB350 but at a lower price and has comparable fuel economy and performance, too. 

A test ride of every bike you shortlist will help you make a decision. 

Since you have a long commute and you want a sporty-looking bike, the options you should be looking at are the TVS Apache RTR 200 4V, Bajaj Pulsar N250 and Honda CB300F. These are machines that will return respectable fuel economy, have enough performance and comfort to tackle your long daily commutes and also be reliable in the long run. 

However, since you have mentioned that your route has a lot of bad sections, we would strongly recommend you take a look at the Hero Xpulse 210. With its upright ergonomics, long-travel suspension and smooth, tractable engine, this will be the most accomplished bike to handle your daily runs. 

Take a test ride of these bikes to see which one suits you best.

Considering your requirements, bikes such as the TVS Ronin, Honda CB300F, CB350 trio, Royal Enfield 350s, and Hero Xpulse 210 will serve you well. All are reasonably powerful bikes that can handle the weight of two-up riding and keep your passenger comfortable. 

A test ride of all these machines with your preferred passenger will help you make an informed decision. 

Since this is your first bike, you should ask yourself what sort of rider you are and then pick the machine accordingly. If you feel you enjoy speed and want a sporty, engaging machine, then something like a KTM 160 / 200 Duke, Yamaha YZF R15 V4 / MT-15 and XSR155 will be good options to consider. 

If you want to have a relaxed riding experience and want something stylish, then a Royal Enfield Hunter 350 or TVS Ronin would be a good starting point. Lastly, if you want a single 'standard' bike that can do most daily things, then something like a Honda CB300F would be a good option. 

If you want something that prioritises fuel efficiency, a 160cc commuter from Honda, TVS, Bajaj, Hero or Yamaha would be the way to go. 

Take thorough test rides of each machine you consider before making up your mind up.
