Kart owners must meet a dB noise limit that is measured from a set ‘sound station’ with an industry standard measuring device.

• 2-stroke kart engine noise limit: 95dB
• 4-stroke kart engine noise limit: 85dB

There is no set tech inspection that karts must pass. However, K1 Circuit reserves the right to deny entry onto the track if a kart is deemed unsafe, too loud or has the potential to damage the track surface.

Kart owners must have gloves, close-toed shoes, and a homologated kart racing suit in order to use our facilities.
