We already know that Michael Mosiman’s move to Monster Energy Star Racing Yamaha is happening, but they haven’t made it official yet. It’s hardly possible to see Mosiman on the bike training or even catch a spy photo. The original plan was for Mosiman to race and make his 250SX debut at the San Diego Supercross this past weekend. However, according to Steve Matthes, it turns out that Mosiman is dealing with a back issue that is affecting him, and he will try to race at the Detroit Supercross when the 250East Championship starts.
Turns out Mosiman has a back issue that's affecting him so I heard he'll try to race Detroit but it's def holding him back. https://t.co/u04X7D1adM— Steve Matthes (@pulpmx) January 23, 2024
