Between the three options you've considered, we'd advise picking between the Kawasaki Versys 1100 and the BMW R 1300 GS Adventure. These are powerful, comfortable, refined long-distance touring machines which will serve you well, although neither is going to be affordable to maintain. 

The BMW S 1000 XR is a sportbike on stilts, and the 1000cc four-cylinder engine from BMW isn't the smoothest motor, so we'd advise you to look elsewhere. 

If you're open to looking outside the ADV bike spectrum, the Ninja 1100SX makes a solid case as a road-going touring bike as long as you're mindful of the ground clearance over bad roads. 

And if you're not hung up on having a '1000cc+' bike only, the Honda XL750 Transalp is a wonderful road-touring machine. It is friendly, approachable, refined and will be by far the most affordable to buy (even if you put the Africa Twin's tubeless rims, extra luggage and protective accessories) and maintain of the lot. 

Try to take test rides of all the bikes listed here before making a decision. 

If you want a retro-looking motorcycle, look no further than the Royal Enfield Interceptor 650. With its old-school looks, smooth yet punchy engine, reasonable comfort and relatively affordable price tag, it is an option that warrants serious consideration. 

Since you already have a Honda, you can take a look at the NX500, which will be a good option with its refined twin-cylinder engine and comfortable long-distance capability. 

If you are open to the idea of a pre-owned machine, in your budget, you can get a Kawasaki Z650 / Ninja 650 / Versys 650. All three are good both in the city and out on the highway, but the Versys would be our pick because it will be the most adept at tackling Indian roads.

The Triumph Speed 400 is ideal for city riding needs, thanks to its smooth, tractable engine. It is lightweight, easily manageable in traffic, and also the most affordable option from this lot of motorcycles. The KTM 390 Duke offers more aggressive performance, sharper handling and has more features, but the ride quality is on the stiffer side to keep in tune with its sporty nature. 

The Kawasaki Ninja 300, the only twin-cylinder motorcycle on your list, has been around for a long time and hasn't received any modern updates. The cost of servicing and spare parts of Kawasaki is also on the higher side. We still suggest you take a test ride of all three bikes to see which one suits you best.

The only option in this price bracket currently is the Kawasaki Versys-X 300, which we have found to be quite average and rather dated in our time with it. We would recommend waiting for options like the CFMoto 450 MT, Royal Enfield Himalayan 750 and the upcoming Norton adventure bike, which will be made in India by TVS. 

If you want a bike right now in this segment, your options are restricted to the RE Himalayan 450 and the KTM 390 Adventure models. 

If you want a brand-new machine, your options are limited to the pricey but capable and reliable Honda NX500 and the charming-looking and soulful but heavy Royal Enfield Interceptor 650. You could also look at a lightly used pre-owned Kawasaki Versys 650 if you don't mind a second-hand machine. Check for a comprehensive service history from an authorized Kawasaki dealer and a meticulous previous owner. 

Among these two, the TVS Apache RR310 is the more modern and feature-packed motorcycle, making it more value for money. The Kawasaki Ninja 300 has not received any major updates in a long time and carries a higher price tag. The servicing and spare parts of Kawasaki will also be priced at a premium, so that is something to take into consideration. Two other bikes you can also check out are the KTM RC 390 and the Yamaha R3. Take test rides of all four bikes so you know which one suits you best.
