The Royal Enfield Interceptor 650 is a proven commodity in our market, and it is a fairly capable city machine, so long as you get used to its weight. Since it uses a big 648cc, twin-cylinder engine, its fuel economy isn't its strongest suit, although that's par for the course for an engine of this size. The Interceptor is the most affordable RE 650 model, and since it is a simple machine, servicing and maintaining it shouldn't be too expensive. 

Since the BMW F 450 GS is yet to launch and we also haven't ridden it, we can't comment on what the bike will be like to ride or to live with. We recommend you wait until media and owners' reviews are out before making a decision.

Do bear in mind that BMW's dealer and service network is far smaller than Royal Enfield's expansive dealer network across the country. 

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. 

Between the two bikes you're considering, we'd recommend you steer clear of the Moto Morini because of its minuscule dealer network and because this bike has yet to prove its reliability in our market. 

Coming to the Royal Enfield Bear 650 is a great bike in many ways, but its stiff rear suspension can be a dealbreaker over bad roads. Instead, we recommend you look at the Royal Enfield Interceptor 650 for highway usage. 

If you're open to the idea of a pre-loved machine, a good condition, used Kawasaki Versys 650 should be available around the Rs 5 lakh mark, which is a similar amount of money as the bikes you're considering anyway. 

Between the Honda H'ness CB350 and the Triumph Scrambler 400 X, we would steer you toward the Triumph bike purely because it offers you significantly higher performance for not that much more money. The Scrambler is also a smooth, comfortable do-it-all motorcycle which has good passenger accommodations as well. The H'ness is also comfortable for two-up riding and is a good city bike, but it will not be able to match the Triumph's performance advantage. 

We would advise you not to go for the Royal Enfield Super Meteor 650 because it is a rather heavy bike at 240kg, which will not be the best fit on traffic-riddled city roads. Moreover, its stiff rear suspension will be the bigger reason to look elsewhere. If you want a RE 650, we would recommend taking a look at the Royal Enfield Interceptor, as that has more pliant suspension and is also much lighter. 

We would advise you to look at other options than the Royal Enfield Bear 650 because we found the rear suspension to be very stiff in our time with it. This means that on less-than-perfect city roads, your back will bear the brunt of the bumps, which won't be ideal given your long daily commute.

Instead, we would recommend you look at the Royal Enfield Himalayan 450 because it has much better suspension comfort and will have exciting performance while also fitting in your price range. 

If your heart is set on a 650cc bike, then the Royal Enfield Interceptor 650 is the best bet for city use with its supple suspension, neutral ergonomics and creamy smooth engine. 

Take a test ride and decide before you buy. 

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.

You can consider one of the bikes from Royal Enfield 650cc, twin-cylinder lineup. Considering that your usage will mainly be in the city, either the Interceptor 650 or the Bear 650 would be a good pick. Take a test ride of both bikes and see which one suits you better.

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.
