2026 Birmingham Supercross – 450SX Heat 1 | Round 10
The 450SX class gets its night underway at Round 10 of the 2026 Monster Energy AMA Supercross Championship — and Heat 1 at Protective Stadium in Birmingham, Alabama marks the beginning of another crucial evening for the premier class championship.
While the 250SX East/West Showdown brings its own unique storyline to Birmingham, the 450SX class has plenty of its own drama to deliver. At this point in the 2026 season, the championship standings are anything but settled, and every heat race result — every gate pick secured, every position gained — feeds directly into the bigger picture of the title fight.
Protective Stadium provides a compact, technical indoor track that puts a premium on clean riding and smart positioning. In the 450SX class, where the margins between the top riders are razor thin, a strong Heat 1 performance can set the tone for the entire night. A front-row gate pick heading into the main event is worth its weight in gold on a track this tight.
The 2026 season has already shown that no lead is safe and no result is guaranteed. Birmingham is another opportunity for the 450SX field to shake up the standings — and it all starts with Heat 1.
