Yamaha FZ series is recommended. Though mileage is li'l downside compared to other 150cc bikes (not a huge difference) - but by looks and power+handling - its one of the best bike in current market. Comes for ~75K/~79K : FZ-S/Fazer.
Want to (can) extend budget till 100K - go for Pulsar 200NS.
Or want a cheaper bike, go for any Honda - there's hardly a thing that can go wrong with a Honda.
