Built for little riders who want the real deal. The Prime Karts XS-4 Sonic gives kids ages 2–8 that “big kid kart” feel with features made just for them. A sport-style adjustable-length steering wheel and racing-themed, UV-resistant graphics bring the energy, while the three-position seat sits only 12″ off the ground for easy on-off and confident control. Coaster pedal braking with reverse helps young riders stay comfortable and in command.
Under the hood, the XS-4 keeps things serious with a heavy-wall steel tube frame and air-filled inner-tube tires for smooth rolling and outdoor durability. Maintenance is simple thanks to removable axles and replaceable bushings. It’s a compact kart that rides like a larger one—perfect for turning neighborhood loops into lap times.
