KartSim Esports vs KartSim Pro – What’s the Difference?
KartSim Esports and KartSim Pro are both built on our advanced simulation platform, but they are designed for very different purposes.
KartSim Esports – Entry-Level Version
KartSim Esports is the basic version of our software. It includes limited content, simplified settings, and restricted setup options. This version is primarily used for select online esports competitions, where equal performance and simplicity are prioritised for competitive fairness and accessibility.
Ideal for: Esports participants and casual sim racers
Limited kart and track selection
Fewer setup adjustments and tuning options
Restricted telemetry and data tools
KartSim Pro – Full Training Suite
KartSim Pro is our flagship software, designed specifically for real-world karting drivers, teams, and coaches. It offers a much wider range of karts and UK tracks, along with advanced setup capabilities, detailed telemetry, and full access to all simulation features. This version is built for those looking to train, test, and improve using a highly realistic environment that mirrors real-world kart dynamics and data.
Ideal for: Club, national, and professional karters
Full access to all kart and track content (including Lidar-based tracks)
Advanced setup adjustments (suspension, gearing, tyre pressures, etc.)
Realistic telemetry tools for performance analysis
If you're serious about improving your performance on real circuits, KartSim Pro is the ultimate simulation solution. KartSim Esports is great for competition and entry-level virtual racing—but it's just a starting point.
