IAME Micro Swift Cadet US

The IAME Micro Swift is the official engine package for Cadet-level competition across the U.S., used in series such as SKUSA, USPKS, and local club events. This 60cc, 2-stroke power unit features an electric start and centrifugal clutch, delivering a strong yet manageable power band optimized for drivers aged 7 to 10. Paired with the Tillotson HW-31A carburetor, the Micro Swift offers smooth throttle response, consistent acceleration, and competitive top-end performance. It’s a tightly regulated spec engine, fostering equal racing and skill development over equipment advantage. In KartSim Pro North America, the Micro Swift engine is digitally replicated to exact spec — including torque curves, RPM behavior, clutch dynamics, and driveability — allowing young racers to train virtually with confidence and realism. Ideal for developing advanced control, braking technique, and competitive racecraft in a controlled, standardized environment.
