The final round of the 2025 Boost Mobile AUSX Supercross Championship will be staged this weekend alongside the Repco Supercars Championship in Adelaide, with the SX1, SX2, and SX3 titles yet to be decided in what is shaping up to be a showdown-type setting at the unique Victoria Park precinct. In Countdown, MotoOnline highlights the major storylines yet to be resolved entering the decider.

6. The SX3 title fight comes down to Adelaide:
Entering Melbourne, the SX3 class appeared as if it belonged to Honda Racing’s Kayd Kingsford, but as is demonstrated in motorsport time and time again, it isn’t over until it’s over. He entered Marvel Stadium with an 18-point advantage, only to see it all evaporate with a DNF as American Ryder Malinoski (Monster Energy WBR Yamaha) is now six points clear of Kingsford, who now sits P3. In between them is Jack Deveson on 75 markers, with Jet Alsop also tied with Kingsford on 72. In short, it’s all to play for this weekend at the Adelaide Grand Final, with a betting man favouring fireworks in the development division.

5. Attention on AUSX:
Supercross is always a fun time on the Australian race calendar, with the 2025 edition of the AUSX series further elevating the product we saw last year. That rings true for the riders included, the commercial aspect, and even on-track safety initiatives were increased. It’s no secret promoters AME Group are up against WSX this weekend – which takes place on the same November 29 date – although the team does a great job from a content perspective, so no doubt they’ll be plenty visible to cap off this year’s championship.

4. Final SX1 podium placement on the line:
KTM-mounted privateer Hayden Mellross is third in the SX1 standings, and really, is in a good position to claim third overall, which would be a standout result for the experienced New South Welshman. Questions surrounded where Mellross was exactly in terms of his racing career, although this supercross season shows he is still plenty capable, and it wouldn’t be at all surprising to see him on an official team next year. KTM Racing Team’s Dylan Walsh is 15 points in arrears of Mellross, while Mitchell Harrison is a further two markers back. Luke Clout and Aaron Tanti are still in this mix, too, holding positions sixth and seventh, respectively, and would no doubt be much more content with a top-five placement than without one.

3. CDR’s last chance at a podium:
This is a strange one to say for one of Australia’s most decorated race teams, but here we find ourselves entering the final round, and Monster Energy CDR Yamaha is yet to achieve an SX1 podium in 2025. We’ve seen flashes from Tanti, Harrison, and Phil Nicoletti, although not enough yet for either rider to net themselves a place on the overall podium. You’d have to think that, debriefing Melbourne, and then looking forward to Adelaide, that there is a big emphasis on getting a blue bike on the podium at the season-finale this Saturday.

2. Blue versus red in the title pictures:
It’s been Honda domination in AUSX some time now, however, Yamaha really came to play this year in both the SX2 and SX3 classes in particular, so much so that they are in the box seat to wrestle championships out of the red corner. Ryder Kingsford is 12 points up on Alex Larwood in the SX2 class, while Malinoski has a three-point advantage in SX3. It’s clear that the BLU CRU has invested heavily into supercross this year from a talent standpoint, and for the spoils to fall into their camp – especially after Honda domination in ProMX this year – would mean a great deal, and be the perfect return on investment in 2025. There’s a lot on the line.

1. Wilson aims for second SX1 title:
Though Yamaha is still in the hunt for the aforementioned titles, it’s all but over in the SX1 class, with either of the Honda Racing teammates – Dean Wilson or Cedric Soubeyras – going to be crowned a premier class champion this year. Wilson has 42 points over Soubs, which means that it is Dean’s to lose, however, as mentioned earlier, this is motorsport, and anything can happen (ask Jed Beaton outdoors…). As for Wilson, he’d reclaim the number one plate that was taken from him last year by Joey Savatgy, which would complete what has been a spectacular campaign for the 33-year-old, US-based Scotsman.
