Queensland brothers Jett and Hunter Lawrence have finished first and second after dominating the Super-Motocross World Championship.

It is Jett’s third consecutive super-motocross championship win, securing him $US1 million ($AU1.5 million) in prize money, while Hunter’s second place netted him $US500,000 ($AU758,000).

The three-round series was raced by the best indoor and outdoor riders from around the world on a hybrid-style track, which concluded at its final stop at Las Vegas on Sunday.

Jett, 22, said it was a challenging weekend after winning the first race of the day and finishing second in race two.

“[In] the first moto, I was able to dig deep and get the win — it saved me for sure,” he said.

“In the second moto, I got another bad start and the boys were riding well. Hunter rode well, which made it hard on me.

“It’s awesome to go one-two with Hunter.”

Just six competition points separated the Sunshine Coast brothers heading into the weekend.

Hunter, 26, narrowly missed out on the championship and would have secured the title had Jett not overtaken Eli Tomac to take second place in the closing laps of race two.

Hunter said he was “gutted” by the result.

“I did everything I could in that one — I gave 110 per cent every time I went on the track and I just came up short,” he said.

“It’s got nothing to do with it being my brother, it could’ve been anyone else and I still would’ve had the same reaction.

“Eli Tomac was on my butt the whole moto and Jett was edging closer, and I think the yellow [safety] flag for Chase [Sexton] — I hope he is OK — I think that maybe helped throw a dog a bone.

“Once I saw him [Jett] get Eli I just wanted to pull into the pits.”

Sibling rivalry

It was Jett’s 10th American Motorcycling Association title since his debut in the 250cc class at just 16 years old in 2020.

He said he had mixed emotions after beating his brother.

“I’m a little confused in the mind right now, battling emotions of wanting to win this but then obviously HJ today, he deserved that win,” he said.

“He executed two really good starts, and the guy is battling with a cold right now.

“I’m bummed to see him sad because he worked really hard — we both worked hard.”

After accepting the trophy, Jett paid tribute to his brother.

“This could’ve been his first 450cc championship but I wanted it really bad as well,” he said.

“It’s difficult because you want to see your brother do really well and it’s difficult competing against him.

“I just told him he rode well, and I said that I was sorry. I don’t really know what to say, I’m sorry.”

Motocross of Nations

The brothers will now look to defend their crowns at the International Motorcycling Federation’s Motocross of Nations race next month.

They will reunite with Kyle Webster after securing team Australia’s first title in 2024.

Australian team manager Michael Byrne said he was optimistic.

“A year on, I’m delighted to welcome Jett, Hunter and Kyle back into the fold and congratulate them on their individual performances so far in 2025,” he said.

“We’ve already proven we can succeed on the big stage, and I’m confident team Australia has the work rate, temperament and speed to do it all again.”
