On Friday, Red Bull KTM confirmed the departure of two-time 250SX East Division Champion Tom Vialle from the team. Now, the team has thanked Chase Sexton for his two years aboard a KTM 450 SX-F, which included his 2024 450 Class AMA Pro Motocross Championship and over a dozen AMA Supercross and Motocross race wins. 

Sexton’s new deal for 2026, with Monster Energy Kawasaki, is expected to be announced soon. For now, check out KTM’s farewell to the #4.

The following press release is from KTM:

Following two seasons in the SuperMotocross World Championship (SMX), Red Bull KTM Factory Racing thanks Chase Sexton for the success achieved together throughout 2024 and 2025.

KTM and Sexton dominated the AMA Pro Motocross Championship in 2024, winning seven of 11 rounds en route to earning the 450MX title outdoors. Despite his title defense being cut short in 2025, this year’s highlight came via a single overall victory at Washougal.

Supercross saw the 26-year-old Illinois native finish third in the 450SX standings in 2024 and he improved to the runner-up position in 2025, falling short of the championship by only two points this season.

In total, Sexton won nine 450SX Main Events onboard the KTM 450 SX-F FACTORY EDITION, with seven of those this year – including Anaheim 1’s high-profile opening round – making for the winningest season of his Supercross career.

Red Bull KTM Factory Racing wishes Chase well for 2026 and beyond.
