Best bike under the budget of Rs. 80,000 for 19 year boy

Hello friends,
My age is 19 years and now I am planning to buy a bike. As, it would be my 1st bike so, I am pretty much concerned about it. My hight is 5.3" and weight 60 kg and I want a bike comaptible to all my physical needs.
Please do suggest me such a bike keeping aside its displacement whether it is 125cc, 135cc, 150cc, 160cc or much more. I am having a budget of Rs. 80,000. And all the related information is given.
Thanks in advance.
