In the 250 ranks, both the East and West coast titles were on the line, with Chase Sexton and Justin Cooper battling it out for the East title, while Adam Cianciarulo and Dylan Ferrandis were set to go head to head for the title in the West.
With all four riders easily qualifying into the nights East v West grand finale, that stage was set for an epic end to the season.
In the battle for the East, it was Sexton who comfortably came away with the title, running near the front of the field from the start of the race, while Cooper battled mid-pack. At the line Sexton cruised through for a fourth-place finish, securing his first 250 championship aboard his Geiko Honda.
While the East title was straight forward, the battle for the West title was a thriller, filled with excitement despite the two riders battling for the title never getting close to each other on track.
Ferrandis launched out of the gate aboard his Monster Energy Yamaha to take control of the race from the start, and with Cianciarulo sitting outside the top five, Ferrandis momentarily held the title in his hands.
Cianciarulo was then able to move forward through the pack, first bringing the points chase back to even, which would secure him the title on countback, then continued to move up through the field and was sitting comfortably in third and looking as though he would break through for his maiden 250 title.
However, it was not to be, with the Pro Circuit, Monster Energy Kawasaki racer making a costly mistake, coming up short in a rhythm section and crashing. While he was able to get to his feet quickly, his bike was badly bent up, and though he was able to continue in the race, he was only able to salvage 20th position.
Up front Ferrandis lived out the perfect night, taking a comfortable race win with the French racer celebrating his first championship in the U.S
‰ÛÏComing into the main, I just asked my mechanic to tell me what Adam was doing and when I saw it at P-10 and P-12, I couldn‰Ûªt believe it." Ferrandis said.
"We trained so hard coming into this weekend. It‰Ûªs more than a dream come true. It‰Ûªs hard to put into words. I‰Ûªm just thinking about all the people that have been with me and supporting me. The team has been behind me the past few years, and I‰Ûªm very grateful to them for believing in me. This is incredible.‰Û
