250cc

Superkarts represent the ultimate expression of kart racing with 250cc engines producing approximately 95-110 horsepower. Modern superkarts feature motorcycle-derived 250cc two-stroke engines with 6-speed sequential gearboxes. Weighing approximately 340 pounds including driver, superkarts achieve extraordinary power-to-weight ratios approaching 650 horsepower per tonne. Superkarts reach 0-60 mph in approximately 3 seconds with top speeds exceeding 160 mph. Advanced features include aerodynamic bodywork generating significant downforce, disc brakes, racing slick tires, and sophisticated chassis design. Superkarts compete on full-size road racing circuits, achieving lap times comparable to GT3 cars despite minimal power, demonstrating extreme cornering capability exceeding 3g lateral acceleration.
