The top half and front bumper of this kart are stainless steel. I had another made ENTIRELY from stainless steel drag links axles and all.. This has to have been made by the same person as the first one I owned. Both were bought three years apart in two different junkyards 25 miles from each other. They both well built, used actual racing kart brakes axles and sprockets and steering wheels, and most of all, both were made from STAINLESS STEEL!!!
