Rather than trying to explain the classes, I thought I'd show examples of each. If you have something that is at least as old as the Evo 2 class (bottom photo), there's a class for it. The age and skill divisions within those classes are pretty standard.

This AJS is a Dinosaur, but could also be raced in Vintage.

CZ (pictured) and Bultaco are popular choices in Vintage

This 78 CR250 is in the Evolution class.

This (early 80ish) Honda is in the Evolution 2 class
