Michael Mosiman

Michael Mosiman, born on 16 July 1999, is an American professional motocross and supercross racer. He rose through the American amateur system, following his older brother Josh, and made his professional outdoor debut in the 2017 AMA National Motocross Championship with the Rockstar Energy Husqvarna factory team. He later raced for Troy Lee Designs Red Bull Gas Gas and for Monster Energy Star Racing Yamaha. His best season came in 2022, when he won the San Diego round of the AMA Supercross Championship in the 250SX West class, leading every lap, and also won a race in the AMA National Motocross Championship. Repeated injuries, including a broken neck in 2024, led him to hold a retirement party before doctors cleared him to return in 2025.
