Briggs LO206 Junior

The Briggs & Stratton LO206 Junior class is designed as a middle-tier four-stroke category for drivers aged 12 to 15. Using the same factory-sealed 206cc engine found in Cadet and Senior classes, the Junior configuration incorporates the blue restrictor slide (0.850") and class-specific weight limits to balance performance across the age range. Known for reliability, affordability, and skill-based racing, the LO206 Junior is featured in major national series like CKNA and USAC Karting, as well as club-level championships across the country. The emphasis remains on driver development, with minimal mechanical tuning. In KartSim Pro North America, the LO206 Junior package is accurately recreated, including slide-based airflow restriction, clutch behavior, and realistic rev-limited power curves — allowing racers to fine-tune their lines and habits in a true-to-life virtual environment.
