IAME Junior X30 US

The IAME X30 Junior is a restricted version of the senior X30 engine, used in top-level Junior classes across the U.S. such as SKUSA, USPKS, and WKA. It delivers high performance with limited output via a junior-specific exhaust and hardcoded RPM limiter, creating a tightly controlled spec racing environment focused on driver ability. With liquid cooling, an electric start system, and digital ignition, the X30 Junior package combines reliability with modern engine tech — ideal for competitive drivers aged 12–15 making the leap from cadet ranks. In KartSim Pro North America, the IAME Junior X30 is digitally modeled with complete accuracy, including rev limits, throttle response, powerband behavior, and clutch dynamics. This makes it an essential tool for training, track familiarization, and setup refinement at the national level.
