The most recent AMA bulletin lists the 34 model indexes of motorcycles that have been homologated and approved for competition in 2023, including standard equipment, newly released special editions, and a variety of two-stroke motorcycles.
At least seven original equipment manufacturers (OEMs) are present, including the "Big Four" of Japan (Honda, Yamaha, Kawasaki, and Suzuki) and the "KTM Group" (KTM, Husqvarna, GASGAS, and GASGAS in Europe).
The list for the 250 class includes fifteen motorcycles: four "edition" 250cc four-strokes, four 125cc two-strokes, and seven normal 250cc four-strokes.
Three 350cc four-strokes, four 250cc two-strokes, seven normal 450cc four-strokes, five "edition" 450cc four-strokes, and eleven suitable 250cc four-strokes make up the 450 Class roster of thirty motorcycles.
Several manufacturers have indicated an interest in Supercross teams, but none made the final list. Beta is slated to join Triumph in 2024.
