The 2014 Australian Supercross Championship (ASX) has been cast into doubt after Motorcycling Australia (MA) sensationally announced this afternoon it has split with Australian Superbike Championship (ASBK) promoter International Entertainment Group (IEG).

IEG has been the promoter of ASX since 2012 alongside its duty as ASBK promoter, which it has run since 2009. Click here for the latest on the ASBK championship‘s future including MA’s announcement.

Supercross is still scheduled to go ahead according to IEG managing director Yarrive Konsky, when contacted late Friday afternoon. Konsky is also owner of the factory Honda motocross and supercross team.

However with Darwin scrapped from the ASBK schedule amidst MA’s separation with IEG, the likelihood of ASX returning to the Top End has been significantly reduced.

Northern Territory Major Events general manager Paul Cattermole confirmed this afternoon it’s yet to complete supercross arrangements with IEG, despite the event featuring as round one on the provisional calendar for 20 September (separated from the ASBK for 2014).

IEG is yet to make further comment regarding the supercross calendar since its initial release on 6 December, in which many rounds were yet to be confirmed.

Stay tuned for more on this developing story.
