Motocross Prodigy Aidan Zingg’s Fatal Crash at Mammoth MX: Inside the Timeline

I hate reporting tragedies, but here’s the full account you need. Sixteen-year-old motocross standout Aidan Zingg succumbed to fatal injuries following a mid-race accident at the 2025 Mammoth Motocross event in Mammoth Lakes, California, on June 28, according to E! News and Dirtbikelover. A Washington native renowned for his precocious talent on two wheels, Zingg “went down in a corner during a race” and was subsequently “run over by multiple bikes” before the competition was halted, Dirtbikelover reported. Contrary to swirling speculation, officials confirmed he was not involved in any mid-air collision. Local law enforcement has been contacted for further details but has yet to issue a statement.
His 18-year-old sister, Alexandria Zingg, paid tribute via Instagram on June 29, sharing poignant photos and videos alongside a heart-wrenching message: “It’s been a day and I feel like it’s been a lifetime. My heart is completely broken.” She reminisced about their playful banter—she joked he would outlive her; he swore she’d perish first—and lamented the plans cut short by fate: “I had everything planned. God had a different plan.” Determined to honor his memory, Alexandria vowed to intensify her efforts in both sport and life, stating, “I’ll forever find myself longing for that last hug, that last ‘I love you.’”
The motocross community poured out condolences. Donn Maeda of SwapmotoLive.com, who first interviewed Zingg when he was riding a 65cc bike, described him as “one of those kids that made an impression on you from the moment you met him.” He recalled Zingg’s cheeky confidence—when asked how soon he’d surpass his father’s record, the teen simply smirked, “Soon, I’m sure.” Maeda reflected on the sport’s joys and dangers from his vantage point at the Mini Monsters event in Illinois, extending his sympathies to the Zingg family: “My heart goes out to them. Rest easy, buddy.” Industry veteran Kris Keefer echoed those sentiments on X, urging fans to “hug your loved ones and tell them you love them” in Aidan’s memory.
Born and raised in Washington state, Zingg had already amassed regional titles and a reputation for fearless cornering by age 16. His sudden passing has reignited discussion about on-track safety measures and response times at high-speed events. Organizers at Mammoth Motocross have pledged to review their protocols, though no official changes have been announced. Meanwhile, tributes continue to flood social media under #FlyHighAidan, and plans for a memorial race are reportedly underway.
And there you have it. Make of that what you will.
