Deegan Doubles Points Advantage with Runner-Up Finish at Thunder Valley
Monster Energy Yamaha Star Racing’s Haiden Deegan strengthens 250MX title defense with a pair of runner-up finishes at the Thunder Valley National / Jun 9, 2025 /

Monster Energy Yamaha Star Racing’s Haiden Deegan overcame adversity to finish second overall at Round 3 of the Pro Motocross 250MX Championship at the Thunder Valley Motocross Park in Lakewood, Colorado. The reigning 250MX champ continued his strong title defense, scoring a pair of runner-up finishes and doubling his points lead. After a technical issue sidelined him in the first moto, teammate Michael Mosiman rebounded to finish seventh in Moto 2 for 14th overall. Getting some experience before Loretta Lynn’s, Kayden Minear enjoyed a strong debut in the series, finishing 16th overall (18-12). Nate Thrasher continued to fight through another challenging round to finish 19th overall (19-18).
Deegan qualified second and got a great start to the opening moto, quickly advancing to second on the first lap. As the clock wound down, he threw down some consistently fast laps and closed in on the leader. Unfortunately, he had a technical issue that changed his focus to securing the second-place finish and scoring valuable points in the championship. In Moto 2, Deegan once again started near the front in second. Although briefly shuffled to third, he reclaimed second and made another charge to catch the leader. With 10 minutes remaining, Deegan made a push and closed the gap to the leader, but then had a tip-over. He quickly remounted to finish second once again, further expanding his championship lead to 25 points heading into Round 4.
Mosiman continued to make progress throughout the day. After qualifying 14th, he started sixth in Moto 1 and advanced to fourth by Lap 7 before a technical issue ended his race early. With the less-than-ideal gate pick, Mosiman found himself towards the back of the field and was caught up in a first-turn pile-up. Undeterred, he quickly went to work and made his way to eighth by the halfway mark and ultimately crossed the line seventh to secure 14th overall.
Fresh off his 1-1 performance at the SMX Next Motocross round during the Hangtown Classic, Minear made his Pro Motocross debut at Thunder Valley. The young Australian qualified 12th and was 14th after the opening lap of the first moto. He continued to push, and despite a couple of tip-overs early in the race, he rode on to an 18th-place finish. In Moto 2, the 18-year-old got a much stronger start, running 10th on the opening lap and battling for a top-10 result, ultimately finishing 12th for 16th overall. Minear looks to continue to build as he gets more seat time at a couple of rounds of Pro Motocross before the Monster Energy AMA Amateur National Motocross Championship at Loretta Lynn’s Ranch.
After a tough first session of qualifying, Thrasher made improvements to close the gap and qualify 17th. From there, he got a great start in third before getting shuffled back. He crossed the line 19th in that opening moto and followed it up with an 18th-place finish in Moto 2 to end the day 19th overall.
The Monster Energy Yamaha Star Racing 450 team heads east to Mt. Morris, Pennsylvania, for Round 4 of Pro Motocross and Round 21 of the SuperMotocross World Championship at High Point Raceway on June 14.

“It was a solid day for us at Thunder Valley, and gaining 13 points in the championship with Haiden. It was an unfortunate mishap for Michael in Moto 1, but he came back with a great Moto 2 charge! Kayden had a great first pro race, and Nate had a tough day and some crashes, but he never stopped charging.”

“It was a good day out here at Thunder Valley. We kind of got lucky in the first one. We had a bike problem, but we ended up making it through. We went 2-2 on the day and doubled our points lead, so we’re stoked.”

“In the first moto, I had a top-10 start and worked forward to fourth before having bike issues, which caused me to exit the race early. In the second moto, I had the 38th gate pick and had to line up on the far inside. I didn’t get a very good start and was caught behind a pileup in the first turn. However, with all the adversity on the day, I was very proud that I was able to ride strong all moto and moved my way from near last to seventh by the end of it. I’m leaving with my head held high and a positive outlook on the season ahead. We have many more races to go.”
Kayden Minear – Monster Energy Yamaha Star Racing #106
“It was a very positive day. My first pro race in America, so there were a lot of nerves going into it. You would’ve seen that in the first race, as I tipped it over three times in the span of two laps. So that was a bit disappointing, but in the second moto, I got a much better start and was running around the top 10. Then I ran a bit tight through the middle of the moto, but I made a late comeback. In the end, it just wasn’t enough. We’ll do some testing with the team and be back at High Point.”
Nate Thrasher – Monster Energy Yamaha Star Racing #41
“It was not a very good day, but we are going to try and get better every weekend. We’ll just keep pushing.
