The fourth round of the Rocky Mountain ATV/MC WORCS Racing Series delivered an action-packed weekend under perfect conditions at E Street MX Park in Marysville, California. The course, stretching just over six miles, featured a diverse combination of terrain—tight single-track trails through the woods, high-speed sections, and even a water crossing through the Yuba River—challenging riders’ skills and endurance from start to finish.

Hometown favorite Dare Demartile delivered a near-flawless performance in the 450 Pro class aboard his Bridgestone/Acerbis/FXR 480 RR. With decades of familiarity on this track—having raced here since the age of six—Demartile snatched the holeshot off the start and never looked back. By the end of the first lap, he had already built a ten-second lead over Tyler Lynn and continued to widen the gap lap after lap. Demartile’s fastest lap of the race came on lap ten, clocking in at an impressive 8:47, underscoring his growing pace and confidence as the race progressed. Despite Lynn’s best efforts—pitting a lap earlier and narrowing the lead to under 20 seconds—Demartile responded with a hot lap shortly after his stop and extended his advantage to over 40 seconds at the finish, leading wire-to-wire in front of a hometown crowd. The battle for the final podium spot was equally gripping.

Giacomo Redondi, riding his Pro Circuit/Precision Coatings Kawasaki, challenged early for second, barreling into the river section alongside Lynn in a bid to make a move. Ultimately settling into third, Redondi held off teammate Ryan Surratt for much of the race until a costly last-lap error slowed him to a 9:18—compared to Surratt’s weekend-best 8:55—allowing Surratt to snatch third by just under two seconds. With the win, Demartile now shares the championship lead with Lynn heading into the final round before the summer break. Redondi and Anthony Ferrante rounded out the top five.

FMF/RPM Racing KTM’s Mason Semmens continued his dominant season with another masterclass in the 250 Pro class, cruising to victory by nearly three minutes. His best lap of 9:00 was over 12 seconds faster than any other rider in the class—an emphatic statement from the points leader as he remains unbeaten in 2025. Behind him, the race for the remaining podium spots kept fans on the edge of their seats. Colton Aeck held second for most of the race aboard his Hatch Racing Kawasaki KX 250, fending off surges from behind. However, a late charge from Noah Gordon brought the gap to just over a second as the checkered flag waved, with Gordon settling for third after an intense two-hour battle.

The fiercest duel of the race came between Gordon and Jake Alvarez, who traded positions at least five times throughout the moto. Gordon ultimately prevailed in the head-to-head, continuing what’s become one of the most exciting rivalries of the season. Both riders are now tied for second in the standings, trailing only Semmens. Jake and his brother Tristun Alvarez completed the top five.

Northern California riders put on a show in the Pro-Am class, with local talent rising to the occasion on familiar soil. Lane Lorenzo was untouchable aboard his GasGas, dominating the field for his first win of the season. Carter Klein, who had swept the previous rounds, settled for second for the first time in 2025. Gavin Bentley secured third after Jaxson Tully was forced to retire early due to a blown clutch. Tully is expected to return strong at Glen Helen. In Saturday morning’s 125 Pro race, the action started with chaos as Travis Damon tangled with another rider off the start and went down hard, injuring his finger. He remounted his Perry Concepts Racing Yamaha and powered through the pain, pushing from the back of the field.

The Alvarez brothers once again delivered a thrilling race for the top spot on their Perry Concepts Racing KTMs. Jake initially held the lead but had to pit, allowing Tristun to reclaim the front position and take his second win of the season. With both brothers now sitting on two wins apiece, their rivalry sets the stage for a dramatic showdown at Glen Helen Raceway.
