You haven't taken it out of your apartment's parking complex, yet you have already lowsided it? No matter how good of a deal you could have gotten on the bike, it would be well worth passing up. Either keep the bike and buy a smaller one to start on, sell it and buy a smaller one to start on, or hit up track schools, although without knowing how to brake skillfully, I doubt they'd let you on the track with others since it would be even more of a hazard then normal.
Hate to be mean, but it's just the truth. These bikes aren't meant for anyone to learn how to ride. They're made for people who know how to ride just because of the nature of how they're made.
Maybe go take the ERC course since you already took the MSF course.
