Rules and Rule Background

This section is devoted to rules and related information relative to events that are not from the AMA classes. It also covers some historical bits about how the rules got there in the first place.

You can always get the standard US rules from the AMA but new events are important and indicate possible directions for the sport. Two KOTRC classes are featured here.

The first class featured here is the 0.40 displacement profile class developed by the KOTRC and called "Profile".

There are two popular classes for small engines in the second section.
