Once you have your gear you are now ready to start studying for your licensing test. To cover the basics we suggest you purchase or borrow a learners book to learn how to ride a motorcycle. They can be purchased from any DMV (Department of Motor Vehicles), Driver Registry or the Government Office in charge of issuing licenses and are also available at various retail stores. The book will teach you the information you need to know to pass your written/computer motorcycle test to get your learners license, as well as teach you basic motorcycle safety, riding skills, and the location and functions of the controls found on all bikes.
The lessons outlined in our chapter on learning how to ride will provide you with exercises you can practice at different points throughout your riding journey. Only practice those exercises that you are ready / are legally able to ride in (eg. do not ride on the highway if your license does not permit it).
We highly recommend that before take your test, or even if you already have your license but have not yet completed a certified training school program, that you sign up to the most reputable motorcycle riding training course that you can find within your area and complete their course.
Trying to learn how to ride a motorcycle on your own is certain to result in suicide or at best serious injury. If you think "I'm not going to try to learn on my own, I have enough smarts and my ego is not so inflated that I realize I cannot do everything on my own - I'll get my friend to teach me." - think again.
Having a friend who is an experienced rider teach you how to ride a motorcycle is rarely a good idea. Why? #1, your friend may tell you (or even think themselves) that they know more about riding than what they actually do know. #2, your friend may know everything there is to know about riding. Perhaps they have been riding for over several decades, have owned numerous bikes and have significant mileage under their belt - but do they know how to teach that knowledge and pass it along to you in a manner that will not only hear but understand? Even teachers need to be taught - they are taught how to teach. #3, does your friend have an empty parking lot with no poles, cars, debris, or other hazards for you to practice on? What type of bike are you going to be learning on? If your friend has significant riding experience they most likely do not have a small engine size bike appropriate for a beginner rider such as yourself.
The bottom line is unless your friend is an experienced rider, who has teaching experience, can provide you with a proper beginner bike and a suitable area to practice on - it is best to take this one to the experts and learn from a reputable riding school.
