As far as I can tell he hit racing right on the head. Yes, it is to compete in a race, and it also is done at top speed, and the part about "out of control" is a little unnerving, but true. As you become an experienced racer most of your laps will be on the edge of the envelope, and to an extent "out of control". But for now we are going to deal with the fundamentals of racing that is very "controlled", and is not done at top speed.

First you must decide what goals you would like to set for yourself as a racer. Are you looking for a way to spend your weekends with friends, and use your time on the track to make you a better street rider. Or are you ready to dedicate yourself "and your money" for a shot at becoming a Regional Champion, National Champion and maybe someday a World Champion. This is the great thing about road racing, you are able to compete on a level that you are comfortable with, both in the amount of money you can afford to spend but also with the talent you have as a racer. What ever the reason, you have picked a sport that is second to none, and is sure to leave you with a feeling of accomplishment that will stay with you for the rest of your life.
