Upgrade from Ignitor to more powerful bike for college student

When I joined senior secondary school, I received my first own bike as Horo Ignitor , bike is good and I loved but now I need to upgrade the bike. Now I have just joined college and I want more powerful bike because now I am bored of its pity power. I always feel it is lacking behind . Now I want more powerful bike, may be 200+ cc. I need bike which looks impressive and stunnning and powerful too.

My budget will be Rs. 200000 at most and I need to finalize my bike in next 2 months.

Please suggest me bike and please tell me if you need to know anything else.
