Japanese motocross and supercross star, Jo Shimoda from the Honda HRC Progressive team has been confirmed to make his premier 450cc Supercross debut at the 2026 Boost Mobile AUSX Open, presented by Monster Energy, on Saturday 7 November, before returning to the 250cc class for the 2027 AMA Supercross season.

Shimoda will race the Boost Mobile AUSX Open, Geelong at GMHBA Stadium on Saturday 7 November before heading west to compete at the Boost Mobile AUSX championship round in Perth at HBF Park on Saturday 14 November.

The announcement comes as tickets officially go on sale for the 2026 Championship, with fans now able to secure their seats to see Shimoda in action alongside some of the biggest names in world Supercross.

Shimoda has established himself as one of the sport's premier international competitors through multiple race wins and championship success on the world stage, including securing the 250cc SuperMotocross World Championship in 2025, edging out Haiden Deegan in the process.

Shimoda joins a growing international rider line-up already confirmed for the 2026 Boost Mobile AUSX Supercross Championship, including Ken Roczen (Auckland and Geelong), Dean Wilson and Cole Davies (Auckland and Geelong)

"Australia has always been on my radar as a place to visit and to compete and to be making my 450 debut there makes it even more special. I had some experience racing the 450cc at Motocross of Nations last year and went well, so I expect to be racing for the win in November. I'm fired up to race in Geelong and Perth, before switching back to the 250cc to prepare for the 2027 season in USA. It's going to be a lot of fun!"
