For this build, we hooked up with the recently retired pro racer Martin Castelo, who wanted to do a project while he recovered from wrist surgery. Martin spent the last six seasons racing Monster Energy AMA Supercross in 250SX for different teams, earning a handful of top-ten finishes along the way. He’s stepped away from pro racing to start his own World Moto motocross academy, where he coaches all different levels of riders, from top amateurs to 50cc kids. He’s also done a few international camps with the goal of bridging the gap between Latin America and the USA.
