The Monster Energy AMA Supercross made a dramatic return to Rice-Eccles Stadium with a thrilling event at Round 16.
took the 450SX Class win, his first since 2019, with one round remaining in 2021. Cooper Webb
crossed the checkers right on Musquin's real wheel for a second-place finish and Malcolm Stewart
earned his career-first 450SX Class podium with a third-place finish in front of the limited-capacity, pod-seated fans inside the open stadium. The Eastern Regional 250SX Class racers returned to racing after a 10-week break and Jo Shimoda
earned his first ever-win with a display of speed and composure under pressure to take the championship battle to the final round.
When the gate dropped for the 450SX Class Main Event it was Ken Roczen
who grabbed the holeshot and immediately took control. Roczen sat second in the title points, down by 16 to Webb, and looked completely in command as Webb struggled to recover from a ninth place start. Musquin sat in second and lost time to Roczen in the early laps as defending champion Eli Tomac
tried to fight forward from just inside the top ten after a bad start.
Webb moved quickly up to fourth with Malcolm Stewart putting heavy pressure on him, making several near-passes as the two tried to climb forward to reach third place being held by Jason Anderson
. Two and a half minutes into the race, Webb sat 5.7 seconds and seven championship points back from Roczen when Tomac had a tip over and dropped back more spots, remounting nearly outside of the top ten.
