AMA RULE CHANGES 2004
AMA SEASON
Changes to AMA road
racing rules will come into effect from 2004 season.
- QUOTE AMA
PRO RACING DIRECTOR (M Vanderslice):
" ... We adjusted the Superbike class so it remains the premier
class in our championship but also took a close look at each of the
support classes. For example, we must objectively recognize the current
state of 2 stroke development but at the same time remain mindful of
the needs of the small but loyal group that enthusiastically follows
that particular class of racing ... "
