There's no such thing as a minor motorcycle accident. Since you're completely exposed, you're much more likely to be injured than in a car accident. Even if you think you're fine, go to the doctor and have yourself checked out -- and get the insurance information of the person who hit you before you go.
For legal reasons, be sure to take photos of all your injuries immediately after your motorcycle accident. By the time you get to court, some of the injuries may have healed, and you may look fine -- and you can be sure your opponent will belittle any pain and suffering you endured, no matter how bad it was.
