Triumph Speed 400 price in Chatra

Taking your considerations into account, bikes we would recommend taking a look at are the Triumph Speed 400 and Scrambler 400 X / XC. 

Both will offer you considerably higher performance than your Yezdi bike and will also be comfortable enough to handle daily commuting duties while being brisk enough on the highway as well. 

If you want an air-cooled, torquey engine, then you could even take a look at the Harley-Davidson X440, which is a comfortable neo-retro roadster that has decent performance. 

Take a test ride of the machines you shortlist before picking one. 

Both options you have shortlisted are lovely city ones, but have very different characters. The Triumph Speed 400 - while it has a neo-retro aesthetic - is quite a quick machine, but its performance doesn't come at the expense of real-world usability. 

The Honda CB350RS - while it may look the most modern of the three CB350 models - has a relaxed, laidback riding experience. 

We recommend taking a test ride of both bikes back to back and seeing which one you like more before you decide. 

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 Triumph Speed 400 is built entirely by Bajaj, which means its spare parts are easy to find and light on the pocket. 

We’d also suggest checking out the Royal Enfield Guerrilla 450. It offers similar performance and running costs, and you might find it a great fit for your riding style too.
