I am 6 feet 3 inches tall. I own and ride a Honda CB 350 H'Ness Anniversary edition, bought in 2022. I love the engine. But I want to upgrade to anything between 500CC to 750CC. May you please recommend a bike in that CC range for city commute and long road trips. Budget between 4 Lakhs - 6.5 Lakhs.

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.
