Round 6 of the Rocky Mountain ATV/MC WORCS Series rolled into Preston, Idaho, where Cache Valley MX hosted a demanding 5.4-mile course that carved through motocross sections and twisted in and out of corn fields. The 120-minute Pro race saw Factory Beta’s Dare Demartile set the pace and dominate, taking the overall victory by more than a minute. In the Pro 250 class, Mason Semmens charged to the top spot, while Racer Fry impressed with a hard-fought win in Pro-Am. With stacked battles across all divisions, Cache Valley delivered a round full of action, endurance, and standout performances that shaped the championship fight.

The Pro 450 showdown at Series was a statement ride from Factory Beta Liquimoly’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 checkered flag, it was Demartile putting on a clinic, crossing the line over a minute clear of the field.

In the Pro 250 class, reigning champ Mason Semmens proved once again why he’s the rider to beat in 2025. The FMF RPM KTM star put on a clinic, not only dominating his class but also charging all the way up to an impressive third overall in the combined moto. The race kicked off with Kawasaki’s Tristun Alvarez pulling a huge wheelie off the line to snag the holeshot, but Semmens wasted no time slicing his way to the front and checking out. Behind him, the battle of the day came down to Jake Alvarez and Semmens’ teammate, Noah Gordon.

Gordon held the advantage early, but Jake Alvarez was relentless, 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 holding the spot to the checkers. Tristun Alvarez ultimately crossed in fourth, capping off a strong weekend that also saw him grab the win Saturday morning in the 125 Pro class, where he continues his hunt for a third class title.

The Pro-Am class delivered its own dose of fireworks as a stacked field thundered down the short start straight, with Kayden Lynn grabbing the holeshot and immediately stretching a gap in the opening laps. Lynn looked strong early, but the sweltering heat and thick humidity hanging in the cornfields pushed riders and machines to the limit—claiming Tully with a mechanical issue that ended his charge prematurely. Up front, Racer Fry was relentless. After settling into second, he found his rhythm in the second half of the race and went to work, reeling in Lynn and slicing past to take control of the lead. Once Fry had a clear track, he never looked back, powering to the Pro-Am victory. Lynn held tough for second, while Gavin Dugan capitalized on the chaos to secure a hard-fought third and round out the podium.

Saturday’s racing delivered just as much excitement as the premier classes on Sunday, with rising talent and fresh faces making their mark. In the Women’s Pro division, the heat was turned all the way up—literally—as riders battled through low 90s temperatures and heavy humidity. NorCal’s Kylie Alvarez wasted no time showing she belonged, putting her moto skills on full display in her WORCS debut. Alvarez charged to the front and never looked back, taking an impressive first-career WORCS victory over current points leader Lauren Woods, making a bold statement that she’s here to contend. In the 125 Pro class, it was Tristun Alvarez who stole the show. Already juggling double duty on the weekend, Alvarez dominated the small-bore class with speed and control, grabbing the win as he continues his pursuit of a third career title in the division. His Saturday success carried momentum into Sunday’s Pro 250 action, proving just how versatile and determined the young rider has become.
