Webb Crowned 2025 450SX Champion in Salt Lake City
Monster Energy Yamaha Star Racing’s Cooper Webb secured his third 450SX Championship, with teammate Justin Cooper finishing third in points standings / May 12, 2025 /

Monster Energy Yamaha Star Racing’s Cooper Webb sealed the deal on a hard-fought 450SX Championship with a fourth-place finish at the Monster Energy AMA Supercross season finale at Rice-Eccles Stadium in Salt Lake City, Utah. His teammate Justin Cooper concluded the season with a third-consecutive podium finish, earning the bronze medal in the premier class championship standings. Adding to the accolades, Yamaha Motor Corporation, U.S.A., won the 2025 Monster Energy AMA Supercross Manufacturers Cup.
Anticipation was high for the final race of the season that would crown a champion, with Webb coming in with a nine-point advantage. He qualified third and then grabbed the holeshot in his heat race, leading the first three laps and ultimately crossing the line second. In the main event, he got another great start and quickly moved into the lead, which he maintained for the first four laps. Webb continued to run a strong pace in the runner-up spot, but as the clock wound down, more riders joined the fight, and the red plate holder dropped back to fourth, which would secure the title. From there, Webb rode a smart race to finish in that position and claim his third 450SX Championship. It was a hard-fought title campaign that saw the North Carolina rider earn five wins and a total of 13 podiums.
Cooper also had a strong start to the day, qualifying second and finishing third in his heat race. In the main event, he got a good start in fifth and made his way to fourth on the second lap and continued to push to claim third on Lap 7. In the latter half of the race, it turned into a multi-rider fight for the podium, with Cooper shuffled back to fourth but then passing his teammate a lap later to reclaim third. He rode on to earn his third-consecutive podium finish to complete a strong sophomore season, which in addition to multiple holeshots and a pair of heat race wins, the New York rider earned four podium finishes and ended the year third in the championship.
Although unfortunately sidelined for most of the season with a broken Fibula sustained during qualifying at the Tampa Supercross, Eli Tomac showed strength at the start of the 2025 season, coming out on top in an intense battle in San Diego to score his 53rd career win. Tomac will return to action for the outdoor season and aims to add another Pro Motocross title to his resume.
The Monster Energy Yamaha Star Racing team gets a weekend off before the 2025 Pro Motocross season kicks off on May 24 at Fox Raceway in Pala, California.

“I want to start off with a big congratulations to Webb on his third title! It was great for the team to have Coop clinch the championship, and Justin finish third in the points. The work our crew and riders put in for this type of success is hard to put into words, so I’m very happy for all of them to be rewarded for their efforts. What a great Supercross season for all three riders, overall. I want to thank them for that, and not forget Eli’s performance early in the season. We’re looking forward to having him back. We will enjoy the weekend off and then move our focus to motocross.”

“Man, what a night! To win this championship means the world to me. There were a lot of hard-fought days to get to where we are at right now, and being a three-time champion is rare territory. I’ve got to give it up to the team, my family, and everyone in my corner. I really appreciate it.”
Justin Cooper – Monster Energy Yamaha Star Racing #32
“It was good to end the season third in points. That was the goal with what we were given. The last three races we podiumed, so that was pretty cool. It was just fun to be in the fight with the guys. I had a great end to the season, and now we look forward to the outdoor season and to bringing this momentum there.”
