D2MX (AMA District 2 Motocross)
AMA District 2's regional motocross championship, racing at seven tracks across NJ/MD/PA/WV/NY; Raceway Park (Englishtown, NJ) and Field of Dreams (Millville, NJ) are the series' anchor venues (riders need 3+ races at each to qualify for year-end awards), with single rounds at Budds Creek MD, Tomahawk MX WV, Pagoda MX PA and Walden MX NY. 'RPMX' is Raceway Park's own venue branding for its D2MX rounds (dual-scored 'RPMX & D2MX Points' on the same dates), not a separate series. Round 15 (Sep 5–6, Raceway Park) doubles as the New Jersey State Championship; two rounds are co-scored 'D2/D6 Combo' races with AMA District 6's Henrietta Classic Series.
