This Week in SMX: Las Vegas World Championship Finale

September 18, 2025

450 Storylines: St. Louis Recap

Hunter Lawrence

HUNTER LAWRENCE: Took control of his own destiny with an overall victory in St. Louis, meaning he can win the Championship with an overall victory in Las Vegas. It was his 24th SMX League* victory tying him with Justin Barcia and Pierre Karsmakers for 31st on the all-time SMX League wins list. His 2nd 450 SMX Playoff victory moves him behind Jett Lawrence for second all-time and he has won three straight Rd. 2’s (2023 250 Class, 2024-2025 450 Class).

Jett Lawrence

JETT LAWRENCE: Holds the points lead after a runner-up overall finish in St. Louis. It was his 7th 450 Playoff podium in 8 starts and 86th career SMX League podium (24th all-time). He is looking for his 3rd consecutive 450 SMX World Championship title by winning the overall or by finishing on the podium with anyone other than Hunter winning.

Eli Tomac

ELI TOMAC: Nailed his 230th SMX League podium, 4th in five 450 Playoff starts, and 2nd in as many Playoff rounds this season. Already has the 2nd most 450 Playoff top-5 finishes even with missing 3 of the 8 rounds since its inception with 5. Tomac’s easiest path to the Championship is winning while Hunter finishes 3rd or worse and Jett finishes 4th or worse.

Jett Lawrence

NOTES: Honda continues their dominance of the 450 Playoffs their 8th win in 8 rounds. Jett has 5, Hunter has 2, and Chase Sexton has 1 for the brand. It was Honda’s 2nd sweep of a Playoff round (2023 Chicagoland, Hunter in 250s and Jett in 450s). Honda has won 12/15 450 Playoff motos as well, with KTM, Suzuki, and Yamaha each winning one. Honda has won all 3 motos this year (1 in Concord, 2 in St. Louis). If Jett clinches the title in Las Vegas, it would be his 10th SMX League Championship, which would tie him with Ryan Villopoto and Jeremy McGrath for 2nd all-time (Ricky Carmichael leads all-time with 16).

450 Class: Las Vegas Facts

  • HISTORY LESSON: The first Premier Class SMX League* round held in Las Vegas was on May 19, 1985, at Las Vegas Motocross Park and included all three Motocross classes (125/250/500). Rick Johnson (Yamaha) swept the Premier Class while David Bailey (Honda) swept the defunct 500cc Class.
  • HISTORIC SUPERCROSS CITY: The 1985 Las Vegas Motocross was the only Motocross round that took place in Vegas. The first 450SX Class round in Las Vegas was held on March 17, 1990, in Sam Boyd Stadium and Jeff Matiasevich (Kawasaki) earned his first and only 450SX Class victory. The series returned almost every season through 2019, only missing 1996, but hasn’t returned to Sam Boyd Stadium since.  Sam Boyd Stadium hosted 26 Premier Class finales from 1993-2019 which is far and away the most in Supercross history. L.A. Memorial Coliseum is a distant second with 9 450SX Class finales.
  • FINALE TRADITION CONTINUES: Sam Boyd Stadium was set to host the 2020 finale until the COVID-19 pandemic scrapped the event. The 2024 Las Vegas Motor Speedway SMX World Championship Finale was a welcome return to the historic racing city and stood as the third SMX League* discipline to host in Las Vegas. Including the 1985 Motocross round, 29 Premier Class Supercross rounds, and 2024 Playoffs Finale, the 2025 Playoffs Finale will be the 32nd Premier Class round held in Las Vegas.
  • CHAMPIONSHIP %: In only 14/31 (44%) Las Vegas Premier Class rounds the winner scored the Championship. Only 10/26 (38%) 450SX Class finales had Championship implications, and the other 16 had already been clinched. Jett Lawrence was 9-points behind in third last season, but used a 1-1 finish in the triple-points Las Vegas finale to tie in the SMX World Championship last year, winning the tie-breaker over his brother Hunter. He is in a much better position this season holding a 6-point lead over Hunter going into the 2025 Las Vegas finale.

250 Storylines: St. Louis Recap

Jo Shimoda

JO SHIMODA: Controls his own destiny with an overall victory in St. Louis. It was his 11th SMX League victory (tied for 66th all-time with Shane McElrath, Davi Millsaps, Mickael Pichon, Jake Weimer, Stephane Roncada, and Gary Jones). It was his 2nd 250 SMX Playoff victory becoming only the 2nd athlete with multiple wins in the class (Haiden Deegan- 4). It was his 6th 250 Playoff podium (2nd behind Deegan) and he is a perfect 8/8 in top-5 finishes (the only athlete with such results).

Seth Hammaker

SETH HAMMAKER: Back-to-back runner-up finishes for his first two Playoff podiums and top-5 finishes. He is 4/4 in top-10 finishes in his 250 Playoff history. He is looking to make his 65th SMX League start in Las Vegas. If he wins he would need Shimoda to finish 3rd or worse to win the title, regardless of where Deegan finished. If Hammaker finishes 2nd, he would need Deegan to finish 3rd or worse and Shimoda to finish 5th or worse.

Nate Thrasher

NATE THRASHER: Made his 80th SMX League start and earned his first Playoff podium overall in St. Louis. With 12 career SMX League podiums, Thrasher moves inside the all-time top-150 on the all-time list. He is looking for a top-5 finish in the World Championship point standings with a solid finish in the triple-point round of Las Vegas. He is the 11th different athlete to earn an overall podium in 250 SMX Playoff history.

Haiden Deegan

NOTES: Jo Shimoda becomes the first athlete to win a Playoff race on multiple brands, no matter the class. He joins Hunter Lawrence as Honda winners in the 250 Playoffs. It was Honda’s first win in St. Louis since 2013. Ty Masterpool (4th): Made his 75th SMX League start and earned his first Playoff top-5 finish. Haiden Deegan (6th): Fell to 2nd in the point standings, needs to win and Shimoda to finish 3rd or worse to win his 3rd straight World Championship.

  • DAVE COOMS SR. EAST/WEST SHOWDOWNS: The first official Dave Coombs Sr. East/West Showdown in Sam Boyd Stadium was in 1997 and Kevin Windham (Yamaha) scored the victory fresh off his Western Divisional Championship. The Dave Coombs Sr. East/West Showdown was solely an exhibition round (non-points paying) through 2010 and featured winners such as Windham, Ricky Carmichael, Travis Pastrana, James Stewart, and Ryan Dungey among others. From 2011-2014 Sam Boyd Stadium featured the finales for both East and Western Divisionals while qualifying the top-10 from each race for a Dave Coombs Sr. East/West Showdown, meaning an exciting night with three 250SX Class Main Events. 2015 returned to a Showdown only, while 2016-2019 featured the first points paying Dave Coombs Sr. Showdown exclusively.
