The Monster Energy Supercross Series will wrap up its 2021 season Saturday in Salt Lake City, Utah, with Round 17, crowning champions in its 450 and 250 classes.

Cooper Webb will carry a virtually insurmountable 22-point lead over Ken Roczen into the season finale and can wrap up his second 450 championship virtually by just finishing the main event (Webb has finished outside the top four once in the past 15 races).

The points leaders also have big leads in the twin 250 divisions entering Saturday’s East-West Showdown.

In 250 West, Justin Cooper has a 20-point lead over Hunter Lawrence. In 250 East, Colt Nichols has a 23-point lead over Jo Shimoda.
