Who is a famous dirt bike rider that is from Australia?

That would have to be Chad Reed. He is doing a SX series of his own here in Australia starting in October in Perth and then going to most states. He has just moved to Suzuki so will be riding yellow in the event as he is entered himself so the local guys many of which are old mates will have to beat him to win the series. My son has raced against his nephew who is an up and coming racer and when he raced against him in Brisbane Chad came to cheer his nephew on.

I find it a little strange that you could forget " The Thunder from Down Under " Bayliss, then Read, then Bayliss again, then Wayne Gardner. Nice one.

Chad Read

Kangaroo Jack - races the 250 Trans-Am series on a Maico.

Jeff Liesk. He was aa Aulstrailin rider that raced the European Grand Prix circuit back in the 80's. No one really knew of him until he came her to ride the US supercross series. He was a member of Team Honda in the late 80's and then returned to Europe and won the world championship.

The "Kangaroo Kid" although i am not sure if he only rides quads, i think he rides bikes. Cheers.....
