TUCSON, Ariz. — The 2026 Vintage Karting Association (VKA) season will kick off in the Southwest with the VKA–VKCA Winternationals, set for January 15–17, 2026, at the Musselman Honda Circuit in Tucson, Arizona.

This popular track features both a long and short configuration — ideal for the wide range of vintage classes. The long layout will be used for 150cc single and 300cc twin and twin Yamaha classes, while the short track option will serve the Historic Rear divisions.

Entry is $100 per driver, with $25 pit passes and RV parking available. Set-up and practice take place Thursday, followed by two days of racing Friday and Saturday. All heats will be 6 laps with transponders, and trophies will be awarded to the top three finishers in each class. Separate practice sessions are scheduled for Historic Rear and Sidewinder competitors.

Hosted in partnership with the Vintage Kart Club of America, the Tucson event promises great weather, competitive racing, and the perfect way to start the 2026 vintage karting season.
