A 125cc go-kart typically reaches speeds between 50 to 70 mph (80 to 113 km/h), depending on factors like weight, engine tuning, and track conditions. Racing models may be designed for higher performance, while recreational models might be slightly slower. The specific speed can also vary based on the go-kart's design and intended use.
