When the opening round of the 2007-‰Ûª08 Toyota AMA Arenacross Series in Des Moines, Iowa (Nov. 2-4) begins, 250cc two-stroke and 450cc four-stroke motorcycles will no longer be raced in order for the Toyota AMA Arenacross Series to focus on 125cc two-stroke or its four-stroke equal, the 250F.
‰ÛÏThe move to adopt 125cc and 250F‰Ûªs in the AMA Arenacross Lites and the AMA Arenacross class is intended to bring the series in line with the AMA Arenacross/AMA Supercross progression system that was established by the AMA in 2006,‰Û
