Monster Energy Mammoth Motocross

New Date: Aug 25 – Sep 3, 2023
The Town of Mammoth Lakes has experienced a record breaking amount of snow this winter season. Due to the significant snowpack, Mammoth Mountain and 2X Promotions worked closely with the US Forest Service to determine our best option for the upcoming Monster Energy Mammoth Motocross. The 2023 Monster Energy Mammoth Motocross has been moved to August 25 – September 3. The event will follow the same format as previous years with Vet Weekend on August 25–27, Mini Days on August 28–30, and the Big Bike weekend on August 31 – September 3. Visit 2XPromotions.com for more information. The Bear Hunt continues!


Every summer since 1968, racers have flocked to Mammoth Lakes for this classic event – the oldest continuous running motocross in the USA. The track has changed a little over the years, but the fun hasn’t. Many racers have honed their skills and made a name for themselves on this track.

Riders like Ricky Carmichael, Jeremy McGrath, Rick Johnson, Johnny O'Mara, Broc Glover, Donny Schmitt, Steve Lamson, Gary Jones, Kevin Windham, David Bailey, Jeff Ward, Ron Lechien, Bob Hannah, James Stewart, Mike Bell, Donny Hansen, Ryan Dungey, Ryan Villopoto, Eli Tomac and many more have raced Mammoth.

It's also become one of the major amateur events in the country as well. You can see the factory riders of tomorrow racing in the mini classes at Mammoth today.
