Following an outstanding season, Red Bull KTM Factory Racing’s Cooper Webb won his first AMA Supercross 450 SX Championship on Saturday (May 4) in Las Vegas, USA aboard his KTM 450 SX-F, securing the Austrian manufacturer’s fourth premier class victory. Teammate Marvin Musquin, who battled hard throughout the season, concluded the series in an impressive third position.

Webb, a two-time Western Regional 250 SX Champion, joined the Red Bull KTM Factory Racing Team at the end of 2018 and the American racer from North Carolina immediately went to work to pair himself with an all-new motorcycle and team. With 5-10 finishes in the first two rounds, the 23-year-old quickly found his stride, as he earned his first-career 450 SX victory by round three. The KTM ace repeated the win once again at round four, before going on to secure a total of seven Main Event victories allowing him to carry strong momentum into 17th and final round in Las Vegas.

Coming in with a 23-point advantage over the rest of the field, Webb played it safe at the final round. Qualifying fifth, the newly-crowned 450 SX Champion secured the holeshot in his heat and assumed the lead early on. With two laps to go, Webb felt some pressure from Eli Tomac and he quickly settled into the second-place position, shifting his focus towards the Main Event.

With a solid gate choice for the main, Webb powered his KTM 450 SX-F into third off the start. From there, he maintained a consistent pace throughout the Main Event to score a third-place podium finish en-route to securing his first prestigious 2019 AMA Supercross 450 SX Championship, an FIM World Championship. KTM is also celebrating its 300th world title victory with Webb’s Supercross win.
