What do i do to earn back my reputation?

Wow, that is a long question. Anyway, if you want to win back your reputation of being a fast bike rider, is this important to you? Do you care what other people think? If you do, then you should be more social and tell people about your fast bike riding skills. Be modest and you can show your gf that you are fast by taking her on a fast ride. (be very careful and drive safely!) :P I hope I helped you. I am sorry if this is a bad answer but I really want to get to level 2
