My height is 5'4' and weight is 58 kgs. Please suggest a suitable bike for me.

The suitable options for you would be Hero Splendor and Hero Passion Pro. And the best of all would be Yamaha Saluto Rx 110 as it weighs as low as 98 kg. The Yamaha Saluto RX gets powered by 110cc, four-stroke, single cylinder, two valve engine designed with Blue Core Technology of Yamaha which can deliver 7.39 bhp power and 8.50 Nm torque. Moreover, the bike also carries good looks and features at a price of Rs. 46,400(ex-showroom Delhi). If this doesn't suit you, Activa 125 by Honda is also a decent choice.
