Progressive American Flat Track
Ryder Bitz-Hay (No. 14) leads the field at the Atlanta Short Track, March 21, 2026.
AFT ProSport 450 is an entry-level professional class, new for 2026, for riders aged 14 to 21 who have never held a professional flat track license. They race production-based 450cc single-cylinder motorcycles with very few modifications.
Beckem Daniels (No. 32), Adam Costan-Wood (No. 88) and Christian Knox (No. 69) at the Ventura Short Track, April 25, 2026.
Adam Costan-Wood raced a Honda CRF450R in the first ProSport 450 season and finished first in the 2026 standings with 29 points.
He won the Silver Dollar Short Track on May 2, 2026. He was second at Parts Unlimited ThrottleFest and at the Caterpillar Nashville Short Track, and third at the Peoria TT.
Riders race on an AFT ProSport license, which is only for this class. To enter an event, a rider must have made the Main Event in the RtAFT 450 class at the amateur event the day before.
The 2026 rulebook outline says a ProSport 450 event may include two qualifying sessions and one six-lap heat race of 16 riders, with every rider going on to the Main Event.
The ProSport 450 Main Event is 10 laps on a Short Track, TT or Half-Mile.
Formats can change for a specific event, so each event’s own schedule is the final word.
Each event page has that event’s schedule and results.
