New Class Names Created For AMA Supercross Series & AMA Motocross Championship

Naming protocol will also apply to AMA National Arenacross Series

PICKERINGTON, Ohio (Sept. 9, 2005) — Beginning with the 2006 racing season, new class names will be in place for the THQ AMA Supercross Series, the AMA Motocross Championship presented by FMF and the AMA National Arenacross Series, announced AMA Pro Racing today.

Instead of relying on displacement to define classes, the new names define each class within the overall championship in a clear, more easily understood manner.

In the THQ AMA Supercross Series the two classes will now be known as AMA Supercross (for 250cc two-stroke and 450cc four-stroke machinery) and AMA Supercross Lites (for 125cc two-stroke and 250cc four-stroke equipment). 

Similarly, in the AMA Motocross Championship presented by FMF the classes will be AMA Motocross and AMA Motocross Lites. The AMA National Arenacross Series will follow suit with AMA Arenacross and AMA Arenacross Lites.

“The beauty of this plan lies in its simplicity, said Scott Hollingsworth, AMA Pro Racing CEO. “With the inclusion of four-stroke machinery into supercross and motocross, tying class names to a particular displacement has been somewhat misleading and potentially confusing to casual followers of the sport. This direction accomplishes several objectives in terms of clarifying the classes, defining the hierarchy between the support and premier class and building on the inherent equity and awareness of the AMA Supercross and AMA Motocross brands.

Hollingsworth pointed out that this naming procedure is similar to what is already in place with other AMA Pro Racing disciplines. “We established this system with our AMA Supermoto Championship and it is working well. The premier class in that discipline is AMA Supermoto and it is supported by the AMA Supermoto Lites class and the AMA Supermoto Unlimited class. The names also intuitively quantify the relative size of the bikes comprising each class without locking us into a specific displacement.

The approach is also consistent with the direction AMA Pro Racing has taken in its AMA Superbike Championship presented by Parts Unlimited where none of the classes are identified with a specific displacement. In that championship AMA Superbike is the premier class supported by AMA Supersport, AMA Formula Xtreme and AMA Superstock.

The naming process for supercross and motocross has been an ongoing initiative at AMA Pro Racing commented Kerry Graeber, AMA Pro Racing Vice President, Director of Communications. “We’ve been studying our class name system for quite a while, said Graeber. “It has been on the agenda of the SX/MX Advisory Board and we’ve considered naming ideas submitted by such diverse groups as fans, riders, sponsors and members of the industry. The objectives were clear but we never saw anything that entirely met what we were trying to accomplish. With these new class names we’re confident that we have now finally met those objectives.

Steve Whitelock AMA Pro Racing SX/MX Series Manager and the person within the organization most closely connected to the discipline agrees. “When I heard the new names I knew we had nailed it, said Whitelock. “The names perfectly communicate the two classes, remove the displacement confusion and fit within each overall championship. I couldn’t be happier and I’m looking forward to rolling them out with the 2006 racing season.
