Final 2025 GNCC Supplemental Rules and National Classes Now Posted

The Final 2025 Grand National Cross Country Racing Series Amateur, Pro and eMTB Supplemental Rules along with the National Classes are now posted online. For convenience, changes are highlighted in red.

In regards to the ATV 250 All-Star Class: No equipment changes were made to this class. After consulting with various partners and experts, it was determined not to allow a 450 motor to be sleeved down to 400cc. To address cost concerns for 2026, the class will be reviewed during the summer break to allow interested parties to present evidence of horsepower comparisons. However, the most plausible solution will be to limit the class to 250cc motors only in 2026.
