from 0 to 50 – 2-stroke 50s or 4-stroke 125s – who is faster?

Hello to each other, I had a conversation with a few friends the other day. Unfortunately, none of us had experiences with 125 scooters and we wondered if 50’s 2-strokes are faster. At traffic lights, we all had the experience that up to 50, who could rarely keep up with 125’s four-strokes nearby. Can anyone confirm that?
