Hi, with out any doubt go for the stylish reliable Honda Unicorn. The bike has reliable 149.1cc, Air-cooled, 4-stroke, single cylinder, digital CDi engine with 13.3 hp @ 8000 rpm of power and has 13 Nm @ 5500 rpm of torque and gives mileage of around 52 to 58 kmpl depending upon the riding style and conditions and has very good comfort in riding and handling and has very good resale value also.

You can also go for stylish reliable Hero Honda Cbz Xtreme or Hero Honda Hunk, both the bikes have same reliable 149.2 cc, Air cooled, 4–stroke, single cylinder, OHC engines with 14.4 hp @ 8500 rpm of power and has 12.8 Nm @ 6500 rpm of torque and gives mileage of around 45 to 55 kmpl depending upon the riding style and conditions and has good comfort in riding and handling.
