The Pro 450 showdown of round six was a statement ride from Factory Beta Liqui Moly’s Dare DeMartile. Launching out of the gate and snagging the holeshot ahead of GNCC standout Lyndon Snodgrass and SLR Honda’s Tyler Lynn, DeMartile wasted no time putting his Factory Beta out front as the pack disappeared into the winding corn maze of Cache Valley MX. From there, it was all gas and no looking back. DeMartile charged hard in the opening laps and quickly built a gap that no one could close. Even when his Camelbak water overheated in the warm Idaho sun, forcing an extra pit stop, he never faltered. Behind him, Snodgrass fought through mechanical troubles that kept him in the hunt early but ultimately opened the door for the SLR Honda duo of Lynn and Carter Klein, making his Pro 450 debut, to power past and secure the remaining podium spots. At the end of 120 grueling minutes, it was DeMartile putting on a clinic, crossing the line over a minute clear of the field.
DeMartile leads the Pro 450-class championship over Lynn, 144-138. Ryan Surratt, who did not start the race, is a distant third on 98.
In the Pro 250 class, reigning champ Mason Semmens demonstrated once again why he’s the rider to beat in 2025. The FMF RPM KTM star delivered an excellent performance, not only dominating his class but also charging all the way up to an impressive third overall in the combined moto scores. The race started with Kawasaki’s Tristun Alvarez pulling a huge wheelie off the line to secure the holeshot, but Semmens quickly moved to the front and pulled away. Behind him, the battle of the day was between Jake Alvarez and Semmens’ teammate, Noah Gordon. Gordon held the advantage early, but Jake Alvarez stayed persistent, closing the gap and making his move as the two went bar-to-bar over the final jump before the finish line, sliding into second and keeping the spot until the checkered flag. Tristun Alvarez finished fourth.
Semmens has a 35-point lead in the class championship over a tied Jake Alvarez and Gordon.
The Pro-Am class delivered its own fireworks as a stacked field thundered down the short start straight, with Kayden Lynn grabbing the holeshot and immediately building a gap in the opening laps. Kayden Lynn looked strong early, but the sweltering heat and thick humidity hanging in the cornfields pushed riders and machines to their limits—claiming Jaxzen Tully with a mechanical issue that ended his charge prematurely. Up front, David Fry was relentless. After settling into second, he found his rhythm in the second half of the race and started closing in on Kayden Lynn, eventually slicing past to take the lead. Once Fry had a clear track, he never looked back, powering to the Pro-Am victory. Kayden Lynn held tough for second, while Gavin Dugan capitalized on the chaos to earn a hard-fought third to round out the podium.
Four-time race winner in 2025, Carter Klein, who did not suit up for the Pro-Am race, still has a comfortable points lead over Kayden Lynn, 122 to 86.
Saturday’s racing delivered just as much excitement as Sunday’s premier classes, with rising talent and new faces making their mark. In the Women’s Pro division, the heat was turned all the way up—both figuratively and literally—as riders battled through low 90s temperatures and heavy humidity. NorCal’s Kylie Alvarez wasted no time showing she belonged, putting her motocross skills on full display in her WORCS debut. Alvarez charged to the front and never looked back, earning an impressive first-career WORCS victory over current points leader Lauren Woods, making a bold statement that she’s here to contend. Woods still enjoys a comfortable points lead.
In the 125 Pro class, Tristun Alvarez stole the show. Already juggling double duty over the weekend, Alvarez dominated the small-bore class with speed and control, claiming the win as he continues his chase for a third career title in the division. His Saturday success carried momentum into Sunday’s Pro 250 race, showcasing how versatile and determined the young rider has become.
