Ew, they took a nice open kart frame and put a **** seat and engine on it. I don't know where you guys race those at, but any raceway around me would laugh. I assume it isn't a real raceway and just race against friends. I used to race against money at a local raceway, which required a seat belt (cage kart) change every 4 years, certified seat, etc.
This is what I am referring to.

That is a nice frame. It is a frame we use there.
