CDR Yamaha Monster Energy has drafted in American Josh Hill and Serco Yamaha has signed young Australian Brad West ahead of this weekend’s second round of the 2022 Australian Supercross Championship (AUSX) in Adelaide.

Hill rode for Craig Dack Racing (CDR) in the World Supercross Championship (WSX) pilot season and will remain in Australia for AUSX this weekend, despite only riding WSX in Melbourne.

The addition of Hill comes following Luke Clout’s injury last Friday night at the opener, requiring surgery on a broken thumb and effectively ending his AUSX campaign. It’s uncertain – but unlikely – if he will return for Newcastle or Wagga Wagga next month.

At 33, Hill has been in impressive form during WSX with CDR riding the YZ450F, claiming fifth in the standings. He completed a full season of AUSX with the factory-backed Yamaha team in 2019.

Serco, meanwhile, has called upon West, the largely US-based 18-year-old who gained considerable experience in SX Futures during Monster Energy AMA Supercross this season – claiming top-five finishes at Anaheim 2 and Glendale.

In for the final three rounds, West will fill the seat of Bailey Malkiewicz, who sustained an ankle injury in round one and underwent surgery directly afterwards. He’s not expected to return until the 2023 season.
