You can consider bikes in the 250cc category, and for your needs, the Suzuki Gixxer 250, Bajaj Pulsar N250, and the Bajaj Dominar 250 should get the job done.
The Gixxer 250 and Pulsar N250 are good for city commuting with their nimble handling abilities, while the Dominar 250 is heavier and more touring-oriented, making it good for highway runs.
Do take a test ride of all these motorcycles with a pillion on board before making a purchase.
