The MX Nationals will celebrate Mother's Day this weekend in South Australia.

Australian Motocross will salute the mothers of the motocross this weekend when the Rockstar Energy Drink MX Nationals, Australian Motocross Championship, resumes at Murray Bridge in South Australia on Sunday, 8 May.

Contested on Mother’s Day this weekend, a host of Australia’s finest rising stars and seasoned veterans will be racing to give their mums the ultimate prize on Sunday – victory at the very highest level of domestic motocross.

Not only is it a case of working overtime to pay the bills to go racing, but cleaning mud-soaked gear, organising travel and sourcing sponsorship are just a few tasks that the mums of motocross take on in their greatly appreciated roles.

For the top levels professionals in Australia, what better what to repay their mums than with a win on Sunday? The Murray Bridge club will play host to round four of the 2011 Rockstar Energy Drink MX Nationals title chase on Sunday, 8 May.
