Shaun Redhead won't be on Team Australia at the world juniors after an oversight by MA.

An age revision to the 2011 Junior Motocross World Championship has ruled Australian hopefuls Errol Willis and Shaun Redhead out of the event, set to take place in Italy on 13-14 August.

Following the announcement of the 2011 Australian Junior Motocross World Championship team, Motorcycling Australia has been forced to make the change to the line-up of the team.

MA today released a formal apology to Willis and Redhead for the oversight, adding two new riders to the 125cc division.

The 125cc class will now feature Luke Clout and Scott Mann for Team Australia, with Joel Milesevic as reserve.

The 2011 Junior Motocross World Championship will be held at Cingoli, Italy on 13-14 August.
