First, I recommend taking a motorcycle riding class. You get your license when you complete the course and it's very informative. Make sure you have all the recommended riding gear. Depending on what type of bike (sport/cruiser/cafe) you are looking for, you will want to try out a few different ones. Find one comfortable for you. Also, I recommend starting out with a more timid engine, but don't be afraid of the bigger bikes as well. If that's what is most comfortable to you and it's what you are wanting, go for it. I started out on a Honda CBR1000, you just have to get used the bike and it's power.
