That why there's a weight limit in karts. Different classes different limits. Kart and driver combined.boggysv said:driver weight difference plays ALOT in karting.
one of my friend(big american, has alot of autoX experience, but weights about 250lbs)..was lapping the same pace as my 10yo brother who just started karting. A few laps later, my brother overtook him.
100cc was 120kg ,Rotax Max is 140kg , or was it 160kg.
Damn long never hangout with karters forgot aredi.
