Monster Energy Yamaha Star Racing to Withdraw from Consideration for 2026 MXoN

Marietta, GA —Due to the demanding schedule of the SMX series, and after factoring in the associated travel and support costs, Monster Energy Yamaha Star Racing and Yamaha Motor USA have collectively decided to withdraw both its 250 and 450 teams from consideration in participating in the upcoming 2026 MXoN in Ernée, France.

“After numerous discussions between the team principals and Yamaha management, both Monster Energy Yamaha Star Racing and Yamaha Motor USA have collectively made the difficult decision to step back from this year’s MXoN competition,” said Jim Roach, Yamaha Racing Manager.

“We’re choosing to prioritize the health and safety of our riders, which includes affording them, and the entire team, a period of time to recover from the 2026 season. When you factor in the logistical challenges and costs of shipping and converting bikes to FIM spec, the team respectfully wants to stay focused on its continued preparation for the upcoming 2027 SMX season.”

The team expresses its gratitude to the AMA for consideration, and appreciates its fans, partners, and the broader moto community for their understanding and support.
