The 11 to 15-year-old riders of the junior class are no longer beginners. These are future champions fighting for victory, no matter if it is the Junior World Championship or a regional championship. In this scene, the 85 SX is considered a winner's bike. With the most powerful engine in the field and a super lightweight, stable chassis, it does not need to shy away from a full size bike.
