How much money does a motorcycle race team mechanic earn?

Ask someone at the reference desk of your local public library for the Occupational Outlook Handbook. It lists all kinds of information you would need to know,(including the salary) of just about any occupation you can think of.
It depends where you live. A motorcycle mechanic typically earns $33,870 in the United States. This makes it lower paid than most installation, maintenance, or repair workers.
