Registration is now open for the 2025 Cup Karts North America Grand Nationals, the four-cycle karting event scheduled to return to New Castle Motorsports Park in New Castle, Indiana, September 25-28.

The ninth annual edition of the event will feature competition from nine different classes, ranging from kid karts to legends classes. Classes will be capped, according to event organizers.

Additionally, the Briggs & Stratton "Outta' the Box Challenge" returns after its inaugural edition in 2024, this season featuring teams and drivers from the Junior class. Participating teams will be given a brand-new Briggs & Stratton 206 engine for the event and will compete to see who can install the engine the fastest before competing with the freshly-installed, untuned engine on track.

The 2024 Grand Nationals attracted more than 600 entries in 2024.
