In genuine cases mostly there is no problem at all. The problem arise when people try to become smarter but forget that those people up there are in a business and have thought of most possibilities to crack and identify if the bike is rented or really personal. With your brother, if the surname is same then with relevant documents you can easily identify the relationship and prove it is not rented one. Else just convince them amicably and you shall be fine.
