The first National title of 2017 was presented to Ezra Hastings in the 450 B Limited class after his trio of second place finishes, while Drew Adams went 1-1-1 for the 51cc (7-8) Limited win. Ryder Ellis topped the charts in 51cc (4-6) Limited, and Aiden Biersteker claimed gold in 51cc (4-6) Special Limited. Landon Palmer snagged the last 50 class moto win in the 51cc (4-6) Shaft Drive Limited Division.

Jazzmyn Canfield was well on her way to earning another title until tragedy struck and her bike blew up on the last lap. Tayler Allred's impressive performance throughout the week set her up to steal the championship away in the highly-contested Girls (11-16) class.

Challen Tennant grabbed the Bell Helmets Holeshot Award in the third 250 A moto, but it didn't take long for Justin Cooper to find himself in the lead. Julio Zambrano was sitting in second at the conclusion of the first lap - his best start to date after a DNF and 25th place finish earlier in the week. Jordan Bailey moved into the second-place position halfway through the race, but couldn't catch Cooper who crossed the line victorious earning the title. Bailey and Joey Crown rounded out the overall podium and the top-three championship standings.

The esteemed 250 B competed in their second moto where Garrett Marchbanks, Joe Shimoda and Derek Drake were all wheel-to-wheel as they rounded the first turn. Marchbanks emerged with the early lead as they jumped through the Go Pro 10 Commandments and never looked back. Meanwhile, the racing action was only heating up behind him. By the end of the first lap, Marchbanks, Drake and Hammaker had settled into the podium positions where they rode that way until the checkered flag. With a 2-1-1 moto tally, Marchbanks was awarded the National Championship.

Once the gate dropped for Open Pro Sport, Justin Cooper was buried mid-pack, while Dylan Greer, Mitchell Falk and Joey Crown saw a clear track in front of them. While running in second, Crown went over the bars across a breaking bump opening the door for Jake Masterpool to secure the runner-up position. Masterpool used this momentum to make the pass for the lead in the Cometic turn just before the Go Pro 10 Commandments. Unfortunately, the same turn that brought Masterpool good luck, turned around to backfire the very next lap where he tipped over and lost the lead back to Greer. Just two laps later another lead change occurred and Jordan Bailey moved into first across the tunnel jump. Bailey ended up taking the moto win followed by Greer. Cooper worked his way from 18th to third, which vaulted him to the top of the championship standings. 

Rene Rodriguez redeemed himself with a 250 C class win after a rough week, but Stockton Stinebaugh returned to the center of the box for the class championship, after claiming the 250 C title earlier in the day. Jett Reynolds sat 1-1 coming into the final moto of the Mini Sr. 1 class, but suffered from a disappointing DNF in the third moto. Matthew Leblanc ended Reynolds championship success and stole the title away. 

Ty Masterpool took the Supermini 2 (13-16) championship after rebounding from an unfavorable start in the last moto. Even with a 23-second win in the Masters (50+) class for Barry Carsten, it wasn't enough to top John Grewe in the championship standings. The fastest ladies in motocross took to the track for their third moto to end the day, where Jordan Jarvis made a last lap pass for the moto win over Hannah Hodges. Jarvis' DNF in the first moto took her out of championship contention, and Hodges was awarded the shield.
