After months of racing around the United States, the 2018 Monster Energy Supercross Series will come to an end with the seventeenth round of the season, the 2018 Las Vegas Supercross. Coming into the weekend, all three championships-250 East/250 West/450-are up for grabs to a group of very talented and capable racers. For the 250 class, the riders will have to earn their points against the combined talent in the 250 East-West Showdown, so every position will count in their quest for the maximum twenty-six points that are up for grabs. In the 450 class, only Jason Anderson and Marvin Musquin have a shot at the first premier class championship of their careers. Although the gap between them is sizable, we know that nothing is certain until the checkered flag flies. Who do you think will hoist championship plates at the end of the evening at Sam Boyd Stadium? Answer our poll and let us know in the comments below!
