The latest Classic Legends bikes have come quite a way from their predecessors in terms of build quality and finish levels. The Jawa 42 FJ, in particular, is a machine we quite liked when we rode it. 

As a machine, it is a capable option, but we haven't had the chance to test its long-term reliability yet. You should also know that the company has a less-than-stellar reputation for after-sales and servicing, so do find out what the exact situation of Yezdi/Jawa service in your area is before you go ahead with the purchase. 

While you don't want the Classic, the Royal Enfield Hunter 350 is a good option if you want something similar in feel but different (read: modern) in its design. It is also one of the more manageable Royal Enfield bikes, which should be approachable for you. We would also recommend you test ride a Royal Enfield Scram 440 because it blends old-school charm and quite a lot of modern capability. 

You can also take a look at the Honda CB350 models because they look and feel more modern than their Royal Enfield counterparts and should be easy to manage in the city.
