Simply put I think Tim and TJ Koyen hit the nail on the head. Watch the OTK Factory video and that should tell you why karts are so expensive. I don’t even want to guess how much those robots cost.
That and there are people that will pay that kind of money to have the best stuff available and win races.
I’m learning in racing if you want to run up front, a top of the line chassis helps a tremendous amount. There is a reason why OTK brands are so popular and until people stop buying them the price is not going anywhere.
Which I don’t see happening anytime soon and unfortunately I think that is one of the reasons why you see karting numbers so low at the club levels because people starting out don’t want to pay $5500 for a new chassis.
