Make sure your gear is secure: buckle that helmet and tighten those glove straps.
Going down on a motorcycle hurts like heck, and even at parking lot speeds it's easy to seriously scrape yourself up. Make sure you're protected by wearing as much safety gear as possible, including gloves, armored clothing, boots, and a helmet (which is required by law in most states, anyway.)
Once you're dressed for the part, you're ready to get on the bike.
