We all love these moments in our sport, when our amazing athletes take a step into the unknown and try and do something special. The Coenen brothers, Lucas and Sasha are sitting in USA now, and waiting for their dreams to come true.

Since they were little boys, they followed AMA racing and not GP racing. Now, with a media day today in Colorado, the boys will get a chance to check out the track and put in some testing. Tomorrow, its time to show the American public why we here in Europe love watching them.

MXlarge will as always give you 100% coverage, from race reports, highlights and interviews. Below is the schedule, in European time. From 4pm tomorrow, you can follow the live timing here, the full results here and the live stream service here.

At 21.15pm in Europe (20.15pm in UK), the opening 450 moto, with Lucas Coenen taking on Jett Lawrence, Hunter Lawrence, Haiden Deegan and Jorge Prado. Battle stations and can the American sensation mix it with the best in the world? Or will it be Coenen springing a surprise?

The 250 class, many expect Sasha Coenen to get the win, but it won't be easy in this new system, new track and new bike. He is good enough though.
