Michael Mosiman will race for Quad Lock Honda’s 250 program in 2027, joining fellow newcomer Cameron McAdoo. Published by Pro Motocross on October 22, the announcement covers AMA Supercross, Pro Motocross and the SuperMotocross postseason. Mosiman is listed to carry number 29 in his first season with the team. [1]
The signing brings a rider with an AMA 250SX West main-event victory and a third-place finish in the 2022 Western Regional championship. The announcement records five podiums in that Supercross season and identifies 2017 as the start of his professional career. It also cites Kevin Windham’s involvement with the program as an attraction for Mosiman. [1]
The release describes injuries as interruptions to his progress, while American Honda’s support is framed around continued development of satellite racing and the 250 class. Those are the team’s stated aims for the program, rather than evidence that the new partnership has already delivered results. [1]
For a reader following the off-season, the useful distinction is between a confirmed move and the questions it leaves open. The announcement establishes the rider, team and championship program. Adaptation to a different working environment, consistency through a season and the eventual competitive order still have to be demonstrated on track.
The scheduled first AMA Supercross round is Anaheim on January 9, 2027. Use the organizer’s current schedule for event details as that date approaches. [2]
That gives the signing a clear next test without requiring a prediction. Watch how the two newcomers build their race weekends and how their results develop across the different disciplines. A roster announcement is the start of that story, not a substitute for the racing that follows.
