Both the Yamaha XSR155 and Royal Enfield Hunter 350 will make for good beginner bikes, but both have distinct riding experiences and USPs. 

The XSR is far lighter, and its fuel economy will also be a tangible increase in comparison to the Hunter. However, it has a taller seat height (810mm) than the Hunter (790mm) so if you are a shorter person or just want the assurance of being able to plant both feet on the ground at a stop, this is something to consider.

Both bikes also have different characters thanks to their engine and chassis combination. The XSR might look old-school, but it is a properly sporty bike to ride and feels more energetic; however, over bad roads, its stiffer suspension will transfer some impacts to your back. On the flip side, the Hunter's slow-revving thumper of an engine will feel better when ridden sedately, and while it's not a lethargic handler, it also cannot be called sporty. 

A proper test ride of both will help you decide which one is the best option for you. 

The Royal Enfield Hunter 350 is the lightest machine in the company's portfolio and will feel quite at home in the city and at the highway speeds you ride at. The Royal Enfield Bullet 350 is a neo-retro roadster that will have the most comfort owing to its spacious, upright ergonomics and lovely ride quality. 

The Meteor 350 will have the most laid-back seating position, but over bad roads, a lot of road imperfections will filter through to your spine. 

A test ride of all three should help you decide which is best for you. 

If you want an adventure bike that is E20 compliant, you will need to either purchase a new bike or search the pre-owned market for a lightly used model manufactured within the last 1 or 2 years. 

If you are looking for a new bike, we would recommend paying the high initial purchase price of the twin-cylinder Honda NX500. It is a rather sorted machine in almost every regard and will feel like a nice step up from your single-cylinder KTM. And since you're familiar with the trouble-free Honda big bike ownership experience, the NX500 makes for a logical step up. 

If you decide to go for something a little less pricey, then bikes like the latest KTM 390 Adventure models and the Royal Enfield Himalayan 450 are also options worth looking at. 

You also have the option of waiting for the new BMW F 450 GS, although its pricing will be similar to the Honda bike rather than the single-cylinder models mentioned above.

A test ride of everything you shortlist should help you make a decision. 

The two Royal Enfield 650s you are looking at are limited in terms of comfort in one way or another. The Continental GT 650 - with its committed rider's triangle - will be comfortable only for short blasts before you start to become uncomfortable. 

Meanwhile, with its rather stiff rear suspension, the Bear 650 will toss you around over anything other than perfect tarmac roads. Between the two, we'd still recommend choosing the Continental because at least you have the peace of mind of tubeless tyres if you fit the accessory alloy wheels to it, which isn't possible on the Bear. 

If you are open to considering the Interceptor, that makes for a fun Sunday bike, too, with far fewer compromises than both of its aforementioned siblings. 

A test ride of all three will help you make up your mind. 

Since most of your usage is inside the city, bikes like the Hero Xpulse 210, Royal Enfield Bullet / Classic / Hunter 350, Honda CB350 trio and the TVS Ronin will make for good options to consider depending on your preference. 

If you do want something a touch sportier but not very rambunctious, then the KTM 250 Duke also makes for a great companion.
