Other than a motorcycle to ride, full gear to protect you while riding in case you fall, the most important thing you need to start riding motorcycles is a good training. Specifically, from a professional because, whatever habits you acquire while learning, stays with you for the rest of your life. So, good training that will teach you the do's and don’ts is a must.
Here is a short list of local (to SoCal) motorcycle (and ATV) training courses you can try. These are all professional, government approved courses that you can trust.
