The second round of the 2011 Rockstar Energy Drink MX Nationals, Australian Motocross Championship, was one of the toughest in recent memory, with Josh Coppins (CDR Rockstar Energy Yamaha), Matt Moss (JDR Motorex KTM) and Errol Willis (Raceline Pirelli Suzuki) victorious at Appin.

Deep ruts formed in the morning, followed by a hard-pack surface in the afternoon, saw consistency as the key in the gruelling four-moto format took its toll in the trying conditions.
