| WMDRA Classes of Competition
The following classes are designed to run the most popular race motorcycles (Street and Pro); however, classes of competition will depend on bike count at each event (4 bike field minimum) and will be addressed at the Rider Meeting prior to qualifying.
Bastard Bike Placement: Competitors who have motorcycles that do not fit into our existing classes, but will pass our safety standards, will be placed into a class where the Technical Director feels they should be competitive. The WMDRA reserves the right to combine classes in the best interest of competition.
