AMA Supercross Round 6 450 Heat 1 Replay | 2026 Seattle Supercross

Here is the blog text for the 450SX Heat #1 in Seattle. In the premier class, the power and weight of the 450s make the rutted Lumen Field track even more treacherous.

⚡ 450SX Heat #1: Premier Class Power Meets Seattle Ruts! | Round 6 Replay
The heavy hitters are on the gate! Welcome to Heat #1 of the 450SX class at Round 6 in Seattle, Washington. As the premier class takes to the Lumen Field dirt for the first time tonight, the stakes are sky-high. In Seattle, the track doesn’t just change every lap—it changes every corner.

For the 450 riders, managing the massive torque of their machines in the soft, deep soil is a balancing act. One wrong twist of the throttle in a rutted corner can send the bike sideways, and with only 6 minutes plus one lap, there is no time to recover from a mistake. The battle for a direct transfer to the Main Event starts right now.

450 Heat #1 Highlights & Storylines:
Throttle Control Mastery: Watch how the top riders manage the power delivery. In the “tacky” Seattle dirt, finding traction without looping out or losing the front end is the key to a fast lap.

The “Slot Car” Ruts: By the time the 450s hit the track, the ruts in the bowls and on the jump faces are deep enough to swallow a footpeg. Watch for the riders who can “lock in” and ride the track like a slot car.

Rhythm Lane Evolution: As the laps click off, the rhythm sections become unpredictable. Watch for riders switching from “triples” to “doubles” as the faces of the jumps begin to crumble under the 450cc power.

The Elite Transfer Battle: With the field as deep as it has ever been, several factory stars will be fighting for those top 9 positions to avoid the nightmare of a 450 LCQ.

The Pacific Northwest fans are on their feet as the 450s scream into the first turn! Who will claim the first premier class win in the Emerald City? Watch the FULL REPLAY of 450SX Heat #1 from Seattle!
