⭐ TrailMaster Challenger 4 300EX — Full-Size 4-Seat EFI UTV-Style Go Kart for Families, Teens & Adults

The TrailMaster Challenger 4 300EX is the most powerful, full-size, four-seat UTV-style go kart in the TrailMaster lineup — built for families who want serious off-road capability, real passenger space, and the reliability of a 300cc liquid-cooled EFI engine.
