Welcome to the online registration page for Round 5 of the Southern California AMA Championship Motocross Series, presented by Prospectors MC. Please use this web page to pre-register for our event.

Select the appropriate entry type(s) below, click “Order Now,” then click “Register” and you will be taken to the registration page to complete the entry form. If you are signing up for multiple classes you will have the option to “copy” your basic information to additional entry forms rather than retyping it. We will see you at the track!
