If you’re new, chassis brand isn’t going to matter. The chassis is just what’s under you to get you around the track. The most important part of a kart is the squishy thing in the seat.
My first chassis was an 8 year old Haase Monte Carlo. After a while, when we got an OTK 7 years newer, I’m not even sure we ran half a second quicker. Don’t worry about chassis, just make sure it’s supported by a shop in the area. You can throw a 206 on anything right now, just grab that and go.
