I'm thinking of buying a motorcycle, but I don't know much about them. What should I know before buying one?

Before you buy a motorcycle, it's important to do some research and consider the following: 
1. What type of bike is best for your needs?
2. How much experience do you have riding motorcycles?
3. Are you comfortable with the safety features offered by different models?
4. How much money are you willing to spend on a bike?
5. What size engine do you need or want?
