The Honda NX200 is a decent option for you, considering your usage, but there are also plenty of other options worth considering before making a decision. From Honda's own fleet, you can consider the CB300F, which will offer you much better performance with similar comfort while actually costing a little less than the smaller NX200. 

The TVS Ronin also makes a good case for itself. It has a torquey, smooth engine with neutral ergonomics and great suspension comfort. At 160kg, it is also a fairly light machine. 

Take a test ride of these - and anything else you might consider - before you make up your mind. 

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. 

Let's dissect each bikes strenghts and weaknesses so you know what you're in for. The TVS Ronin is a relaxed, comfortable, peppy and relatively fuel-efficient machine. If you don't mind how it looks, the Ronin is a machine that will keep you satisfied for a long time.

The Yamaha XSR155 is essentially a handsome MT-15 with some small ergonomic changes. It is the sportiest machine of all the bikes you're considering and that reflects in its canted forward riding position and stiff suspension setup. If you have good roads around your residence, then the XSR makes for a compelling purchase.

The Royal Enfield Hunter 350 and the Honda CB350 H'ness are similar machines with somewhat familiar riding experiences. Both are comfortable, look good and have big, torquey air-cooled engines. The difference is that the Honda feels like a more substantial bike that needs a little more effort when riding, owing to its super tall gearing - not necessarily a bad thing, if you're into this sort of thing. 

The Hunter will feel smaller, lighter and more flickable inside the city. Additionally, its well-judged gearing will ensure you don't have to make many gear changes. 

Take a comprehensive test ride of all 4 before you decide.

Since this will be his first bike, we recommend getting a bike with dual-channel ABS (at the very least) in terms of safety features. Keeping his physique in mind, bikes like the Hero Xpulse 200 / 210, Royal Enfield Bullet / Classic 350, TVS Ronin, Honda CB350 trio and Suzuki V-Strom SX will be good options to consider. 

Do take him for test rides of all of these so he can decide which one fits him best. 

If you are open to the idea of a larger, premium machine, then bikes like the TVS Ronin, Royal Enfield Hunter 350 and Honda CB350 will be the options we recommend. If you want to instead go for a commuter bike, there are loads of great options in the 160cc space, such as the Honda Unicorn / SP160, Bajaj Pulsar N160, TVS Apache RTR 160 4V and Suzuki Gixxer. 

Take a test ride of all the bikes you shortlist with a pillion to see what suits you best. 

The Bajaj Pulsar N250 you have shortlisted is a great option because of its smooth engine, plush suspension and great fuel economy. 

Other bikes you can consider are the TVS Ronin and Honda CB300F. The latter is similar to the Pulsar in its style and riding experience, but the former is slightly more cruiser-y in its styling. 

A test ride of all three should help you figure out which bike suits you best.
