"Appin is one of the best facilities in Australia - it's a natural fit for us to come down."
That's the view of MX Nationals series organiser Kevin Williams as Appin prepares to host round one of the 2019 championships this Sunday.
The Pirelli MX Nationals is rated as Australia's premier motocross championship, with 10 rounds held across the country.
Williams said more than 120 top-class motocross riders would head to Macarthur for the event.
"This event is the V8 Supercars of motocross," he said.
"It will have a $450,000 [tourism] impact for the region and more than 500 officials will come down."
Williams said 2019 marked the sixth successive year that Appin had hosted MX Nationals action.
"But it's the first time the opening round has been held there," he said.
"Appin has a very well manicured track - it's a natural fit."
Sunday's round will be run with support from the Macarthur Motorcycle Club.
There will also be plenty of local riders, including Appin and Oakdale-based rider Luke Clout.
"The Macarthur club is the biggest club in Australia with more than 4500 members," Williams said.
The MX Nationals action will get under way with practise and qualifying from 8am on Sunday, March 17.
The first race will begin at 10am.
Williams invited everyone to come along and enjoy the event.
"It will be an action-packed day of racing," he said.
Round one of the MX Nationals will be held at the Macarthur Motorcycle Complex on Brian Road, Appin.
