Non-EU buying a superbike in Poland

Hi Guys I'm from India and studying in Poland, I want to have a super-bike, Am i allowed to buy one and register it my name?.

If i can buy one,
What documents should i provide?
Can i buy a used super-bike ?
Can i buy it from other schengen countries and use it in Poland?

By a 'super-bike' do you mean a racing motorcycle? If so, I guess you can buy one in Poland regardless of your residence status. If you can register one - probably yes (if you have a valid Polish/EU drivers license). But my suggestion is - buy a super-bike after you're 30 at least ;)
