Why would the top speed be lower? Because of increased friction with the ground due to the weight? Ignoring friction, I think what I said would be true.
I hadn’t actually thought about it before but as an incredibly skinny person what you said lines up with my experience in a kart. I could seemingly go slightly faster than others but more easily span off and lost control.
Actually, I'm talking rubbish since without friction there wouldn't even be a top speed. It's true that having a high top speed is only useful if you have enough time to accelerate up to it!
