Aussie FMX legend Robbie Maddison as well as off-road racing’s Greatest Of All Time Ricky Carmichael are both confirmed in the line-up for this year’s AUS-X Open in Sydney over 11-12 November. Maddison will be headlining the event’s FMX Best Trick Competition after attending as a spectator in the 2015 event, while Carmichael will join the likes of Aussie supercross hero Chad Reed and current world-number four Jason Anderson as the pair square off after their controversial coming together at the Las Vegas finale last month.
