Re-posted from the ATVA official website:
November 2, 2004 – Four-stroke ATVs in 90cc racing classes will be allowed to have displacements as high as 125cc beginning in 2005 under a new rule approved recently by the AMA Congress.
Motorcycle classes have allowed for this bump in displacement for some time.
Under other new rules:
Engines won't be allowed to be downsized to qualify for the 200cc two-stroke/300cc four-stroke Youth Production class. For example, you can’t take a 250R and downsize it to 200cc and run it in this class.
In motocross, each ATV must have an individual gate—no sharing of a single gate. Apparently at some tracks, youth ATVs racers would share a single gate. If one ATV jumped the start, it would hold up both racers and not just the rider that jumped.
The definition of Production ATVs has been clarified. Under the rule about stock frames, Congress has added the following: "Only bolt-on components allowed."
The rule that referred to “suspension geometry” has changed a little for clarity also. It now reads: "ATV OEM frames in the stock and production classes may have material added for strength. These changes shall not affect frame geometry." The word suspension has been deleted.
If you have any questions about any of these rule changes, please contact ATVA Director Doug Morris at (614) 856-1900, ext. 1337.
