Need Advice buying Used Super bike in India (budget Rs. 7lakhs - 8 lakhs)

I am driving Yamaha R15 version 1 from long time and now I feel I should go for a super bike and I am seriously planning to buy a used super bike and my budget is Rs. 7 lakhs or so, I think I will be fine with a bike 2008-2010 in this budget and my perference is to buy 1 liter bike . Could be great if I can get Yamaha R1 but I am not sure about paper work because I don't want gray market bike.

So friends please suggest me what kind of bike I can get in such price and what are the things I should know before buying a used super bike in India.


My other concern is if I buy used SBK then what about its component and expenses we generally see in a used bike ?
