The 2024 AMA Supercross 450SX finale in Salt Lake City delivered a high-intensity race from start to finish. Aaron Plessinger secured the holeshot, closely followed by Cooper Webb and Chase Sexton. Webb wasted no time taking the lead on lap one, but Sexton wasn’t going to let him go that easily.

Webb maintained second for much of the race, with Justin Cooper behind. Cooper, fully aware of the championship stakes, chose not to pressure Webb. Shane McElrath looked promising early on but went down mid-race.

Despite finishing fourth, Cooper Webb had more than enough points to secure his third Monster Energy AMA Supercross 450SX title. Chase Sexton took the win, followed by Stewart, Cooper, Webb, and Joey Savatgy.
